You’ve probably heard the terms locked and unlocked when it comes to cell phones, but many people do not know what that means or how to tell the difference between a locked and unlocked phone. This guide will provide all the information you need on locked and unlocked phones, how to tell the two apart, and what the advantages and disadvantages are of each type are.
Overview of the Differences Between Locked and Unlocked Cell Phones
Locked Cell Phones
Locked cell phones can usually be purchased by a wireless network and generally only work with that specific network.
Unlocked Cell Phones
Unlocked cell phones, however, are not connected to a specific network which means that they have the potential to connect to different networks.
Deciding Between Locked and Unlocked Cell Phones
Although choosing an unlocked phone that can work with different carriers might look like the most obvious choice, the choice between locked and unlocked cell phones can be a little more complicated. Here are some deciding factors that can help you choose between a locked and unlocked smart phone.
Price
Unlocked cell phones are usually much more expensive than locked phones when initially purchasing them, by as much as two or three times. While this may seem surprising, the reason behind this is simple. When you buy an unlocked phone, you are paying the full purchase price of the phone whereas most locked phones allow you to pay less for the phone because they take on some of the purchase price.
Locked cell phones are typically less expensive than unlocked phones because wireless carriers often offer great deals on their smart phones when you commit to a long-term contract. Although in some networks it may seem like you’re getting a great deal on a smart phone by buying one this way, people will end up paying more in the long run because of the monthly contract fees. If you do try to get out of your contract early, there is an early termination fee that helps the phone company cover the cost of the phone.
Basically, buying an unlocked cell phone has a higher upfront cost, but it does allow you to change carriers at your leisure which can help you save money by not being tied to a long-term contract. However, if you are already with a carrier that you love and have no reason to change carriers in the next two years, choosing a locked cell phone can help you save money. Take into account that most phones can be unlocked even if they are tied to a contract.
Technological Differences
Whether a phone is locked or unlocked, it can still only use the two main types of wireless technology that all phones use to connect to a network. These technologies are GSM technology and CDMA technology. Phones that use CDMA technology are not able to connect to wireless networks that use GSM technology, and vice versa. This is an important point particularly with unlocked cell phones because it does limit the types of networks the phone can connect to.
Technology Utilized by Locked Cell Phones
The technology used by locked cell phones will vary depending on the wireless provider that it is connected to. However, the technology is not as important in locked phones as is the provider. Locked phones purchased through AT&T, for example, will only work with AT&T. They are on the GSM network, but because the phone is locked, it cannot connect to towers owned by other wireless providers that use GSM technology. This makes a locked phone’s service a little easier to understand because it’s a little more limited.
Technology Utilized by Unlocked Cell Phones
Each phone will be different in terms of the type of technology it operates on. It will either be GSM or CDMA. If it is a phone that uses GSM technology, it can connect to AT&T and T-Mobile. If it uses CDMA technology, it can connect to Verizon and Sprint. This is important to understand if you are buying an unlocked cell phone to use on a specific network because an unlocked cell phone that uses GSM technology could not connect with Verizon’s networks. If you are purchasing an unlocked cell phone and planning on using a particular network, be sure to check which type of technology it uses before making your final decision.
Dual Technology Cell Phones
There are also unlocked cell phones which can actually use both CDMA and GSM technologies. Many of these are considered dual SIM devices which means you can install two SIM cards of two different wireless carriers. That means that by switching out SIM cards, you could potentially use any network by switching out the SIM cards.
How to Unlock a Locked Cell Phone
Unlocking a phone is quite simple and do not required technical knowledge. In most cases all you have to do is to enter the code provided by UnlockCode4U.com when the phone prompts for it.
What you need to know when it comes to unlocking a phone is that to do so, you can contact UnlockCode4U and we walk you through the necessary steps to unlock your phone.
This process happens most often when a customer is planning on leaving the country and want to be able to use their phone in places where they won’t be able to use their regular service provider. They can then use their phone to connect to the networks in the country they are visiting, and then are able to quickly re-connect to their own carrier when they return.
How to Check if a Phone is Unlocked or Locked
Since most cell phones don’t have “locked” or “unlocked” written across their screens, it might take a little detective work to figure out which one they are. However, there are a few simple tricks that you can use to figure out if a phone is locked or unlocked.
Branding
Most locked cell phones will have the brand of the specific carrier they were built for, so finding a brand name or a carrier’s logo is usually a good indication that it is or was a locked phone. While nearly all phones will have the logo or name of the manufacturer, unlocked phones will rarely carry any additional brandings.
If there is not an obvious wireless carrier logo on the outside of the phone, you can also check for branding by turning the phone on. Most locked phones will have the carrier’s logo appear while the phone is turning on.
Duel SIMs
Phones that have duel SIM card ports are nearly always designed to connect to different types of technologies or at least different types of wireless providers. This is a very good indication that the phone is unlocked and was originally sold as an unlocked phone because if it was locked for just one carrier, there would be no need for an additional SIM card port.
Model Number
To confirm whether the phone is locked or unlocked, you can search for the model number online. This can be found on the back of the phone, usually beneath the battery or on the battery door. After you locate the model number, search for it online and you will soon discover if the cell phone was originally sold as unlocked or locked. You can also discover what type of technology the phone uses by doing a model number search.
Insert a Different SIM
The best test to find out if the phone is locked or unlocked is to try a SIM card for a different network. Once you’ve done the model number search to confirm the type of technology it uses, place a SIM card from a different carrier that has the same technology. If the phone is unlocked, it will quickly connect to the new service provider and you shouldn’t have any other problems. If the phone is locked, in most cases it will prompt for the Network Unlock Code.
Benefits and Downfalls of Unlocked and Locked Cell Phones
Benefits of Unlocked Cell Phones
- Freedom to choose between different wireless carriers
- No long-term contract so you can change carriers whenever you want without penalty.
- Unlocked phones don’t come with any extra bells and whistles that the carrier installs so you can just add the apps and programs that you want.
- These can save money in the long run because of the extra expenses that come from being locked into a long-term contract, and by being able to choose a wireless company that offers better pricing options.
- Unlocked phones typically have a higher resale value if you decide to sell your phone. This is because they are sought after by a larger audience of people and are preferred by people who travel overseas as well as people around the world who don’t have access to the wireless carrier in your area who are looking for a good smart phone.
- It’s also great if you travel out of the country because you can easily switch out your SIM card when you arrive and then begin using the foreign wireless carriers until you get back to your homeland.
Downfalls of Unlocked Cell Phones
- The only real downfall is the upfront cost is a lot higher for unlocked cell phones. However, by doing some math, you should be able to figure out whether or not an unlocked cell phone will actually save you money in the long run based on the total cost of monthly phone bills combined with monthly phone payments.
Benefits of Locked Cell Phones
- The initial cost of a locked cell phone can be a lot less expensive, particularly if you are already planning on using a particular wireless network carrier, and are not worried about committing to a long-term contract.
- There are also a number of warranty options that usually come with locked cell phones that you can choose from because many wireless carriers have their own warranty programs that allow you to work directly with your carrier if there are any problems with your phone. This avoids the need for sending your phone off to the manufacturer if there are any problems and could save you money if there are specific problems that are covered by the warranty.
- Locked cell phones may be found in a much wider variety than unlocked cell phones because the wireless carriers stock a number of different phone options whereas manufacturers do not put out as many varieties of unlocked phones. This can let you more freely choose from the many types of phones that are available to you.
- Most phones from GSM Carrier networks can be easily unlocked by unlock code without voiding the phone's warranty.
Downfalls of an Locked Cell Phone
- You are not able to choose which wireless carrier to work with, and if you do decide to change carriers in the future and you will either have to go through the process of unlocking your phone or buy a new phone.
- Most phone companies are able to offer great deals on their locked cell phones because you have to sign a long-term contract which will last either one or two years.
- Many carriers include extra apps and features installed onto all of their locked phones, all of which pertain directly to their company. These usually cannot be easily uninstalled which means you are stuck with these programs whether you want them or not.
Other Information on Unlocked and Locked Cell Phones
When it comes to unlocking a GSM phone versus a CDMA phone, there are a couple of notable differences. Because most phones that use GSM technology also have removable SIM cards, they are usually more easily unlocked when compared to CDMA phones. Many CDMA phones have built-in SIM cards which means they cannot always be unlocked, even with an unlocking code directly from the manufacturer. To unlock a phone that uses CDMA technology, you may have to bring them in person to the wireless network you are trying to connect to once you are able to get them unlocked.
Worldwide Cell Phone Technologies
While the United States almost exclusively uses either GSM or CDMA technologies, most of the rest of the world uses GSM. Industry experts predict that the world is headed toward exclusively using GSM technologies. If you are looking for an unlocked cell phone in order to travel, it is best to find one that uses GSM technologies since it is more readily available around the globe.
Does your Android phone keep displaying the “Emergency Calls Only” screen? Is it no longer in service? Are you no longer able to receive or make phone calls or messages? When your cell phone has become about as useful to you as a brick, it’s time to start troubleshooting to get an answer as quickly as possible. This guide was written specifically to help you get your Android phone off of “Emergency Calls Only” mode and back to good working order.
Software or Hardware Issue?
The first thing to consider is whether this may be a software issue, a hardware issue, or a problem with the network. Hopefully, it is a software issue as these are usually the fastest and easiest to fix. Software issues mean that there is something wrong with the programming within the phone. Hardware issues arise from wear and tear or other damage to the actual physical components of the phone, and are often the most difficult and expensive to fix. Network problems can be difficult to pinpoint and although they can be easy to solve, they are also difficult to find simply because the problem may not be with your phone.
As you go through this guide, be sure to follow every piece of advice even if you think it may not apply to your situation.
Restart Your Device
The first step is to simply restart your devise. This forces your phone to completely drop the network connection and then reconnect once the phone is back on so many minor software glitches can be fixed this way. To restart your Android, power down your phone and then wait 30 seconds to a minute before powering it back on. Allow it to completely turn on before you try to check if it’s working again.
Second Level Restart
If a simple restart didn’t work, the next step is to try a second level restart. This is also known as a soft reset and is also helpful for fixing minor software glitches. To do the second level restart, begin with your phone turned on but not plugged in. Then, remove the battery from the phone. Wait 30 seconds to a minute, then replace the battery and power the phone on.
Note that there are some Android phones that do not have removable batteries. If you have one of these types of phones, then you will have to skip this part since you will not be able to remove your phone’s battery.
Check the SIM Card
Not all Android phones have SIM cards that you can remove or that you have access to. If yours does not have a removable SIM card, then you won’t be able to do any troubleshooting with it, so feel free to move onto the next section. However, if you do have a removable SIM card, keep reading carefully as there are a number of problems that can arise with SIM cards.
SIM stands for Subscriber Identity Module, and is what all cell phones use to communicate with its wireless network provider. However, SIM cards are not exclusive to a phone and contain information such as your phone number and contacts although it is not the same as a memory or SD card. Because your phone’s SIM card is what is connecting you to the network, it is an important thing to consider when getting Emergency Calls Only error messages. In fact, if you take the SIM card out of a phone that is working fine, that phone would also display and Emergency Calls Only message and would no longer be in service.
To check your phone’s SIM card, carefully remove it from its slot and check it for any damage or dirt. Make sure that the connections are also clean and dirt-free. To be certain, you can use a pink pencil eraser to clean off the connector parts of the SIM card. In addition to checking for dirt or damage, you will also want to make sure that the SIM card is fitting properly in its slot.
If there are obvious signs of damage to the SIM card, particularly on the connectors, head out to the closest service center for your network to get a new won. AT&T stores will be able to provide replacement SIM cards for AT&T users, and T-Mobile will provide replacements for T-Mobile customers, and so on.
If you’ve had your SIM card for a while, it might simply have worn out, particularly if you have switched it a few times from phone to phone. SIM cards that are more than a year or two old may need to be replaced simply because they are older, so replacing your card will help you have the most up-to-date SIM card available.
Testing SIM Cards
If you suspect it might be the SIM card but aren’t sure, there is an easy way to test them without having to trek all the way to the phone store. Simply find someone else who has the same type of service as you and slip your SIM card into their phone. If their phone also loses service and begins to display an Emergency Calls Only error message, than it is definitely your SIM card, and a quick replacement will get your phone back up and running.
Location Problems
Does your phone only display the Emergency Calls Only message in certain locations or is it a constant problem? If you find that it only happens in certain places, then it may simply be a signal problem with your network provider which means you’ll just have to keep moving to find an area that has signal. When you find your phone loses service, ask other people who have the same service provider as you to see if they are having the same problem. If they still have service, it may be your phone.
Try Searching for Networks
Sometimes the problem is that the phone is not connected to the network. To manually search for networks, go into settings and then tap on “Wireless and Networks.” From there, tap “Mobile Networks,” then “Network Operators,” and then choose to “Search Networks.” Next, restart your phone and see if you have service again.
If you are not able to tap on “Network Operators” because the phone has it grayed out, then your phone is already set up correctly to connect to the networks and it’s time to move on to the next step.
Lost or Stolen Phones
If phones have been blacklisted (reported as lost or stolen), many service provides will put a block on the phone's IMEI to cut it off from service and prevent it from making and receiving calls. This is meant to discourage theft, and could possibly be causing your phone to have lost service.
Typically, only you or other people who have access to your account can report a phone lost or stolen, but mistakes are sometimes made, so although it’s not likely that this is the problem, checking the status of your phone is as easy as calling your wireless service provider to ask them about your phone’s status or requesting your IMEI Status Report with us.
Although cell phones no longer have visible antennas, these antennas are no less important today as they were in the past. Now, they are often built into the phone’s back plate. This means if the plate is removed, damaged, or not properly attached you may find yourself without service.
If you know the back of your phone has been damaged or the back battery cover no longer fits correctly for some reason, this may be causing the Emergency Calls Only error message. You can usually get into contact with the phone manufacturer to get a replacement back plate.
Physical Damage
If your phone was dropped or otherwise received some type of physical damage shortly before the error message showed up, it could be that your phone was damaged and you will need to replace it. However, before shipping it off to the manufacturer, keep reading through this guide to check other issues just in case.
Water Damage
Most phones will have something known as an LDI, a Liquid Damage Indicator. This strip on the inside of the phone is designed to change colors if the phone gets exposed to enough water to do damage. Find the LDI and check its color. If it is white or white with X’s on it, then this is not likely the cause of the problem. However, if it is pink or red, then the phone has received water damage which means you have probably found the source of the problem. The bad news is that this also means the warrantee is void.
Replacement Phones
If you do end up getting a replacement phone and you find yourself facing the same Emergency Calls Only error message, it is likely that the problem is not related to your phone’s software or hardware, but the network itself. In this case, there’s really nothing you can do except switch wireless providers.
Timing and Environment
Sometimes, you will find yourself with very poor service if you try to make phone calls at certain times of the day and in certain environments. For example, trying to get a phone call to go through while stuck in rush hour traffic near a big city will likely be difficult because of the sheer number of people that are also using the same cell tower as you. Although this doesn’t normally cause the Emergency Calls Only error, it can cause you to lose cell phone service at times.
Weather Conditions
This happens much less frequently and is not likely to be the cause of your problems, but it is something that can cause interference with cell phone service. Everything from rain, snow, wind, and hail can cause poor phone service. Severe weather conditions and natural disasters can even knock out cell phone towers that leave people without service for a period of time.
If you have had a natural disaster or severe weather in your area, a little research can usually uncover whether or not there are any towers down in your area. If there are towers down in your area that are going to be down for a while, you may consider cancelling your service for a time or switching service providers. In most cases, these towers are replaced rather quickly because service providers don’t want to lose customers, so it’s usually best to just wait it out for a couple of days.
Software Issues
Once you have ruled out some of these hardware issues and other environmental factors, you can begin to go through this list to check for any possible software issues that you can easily fix yourself.
Applications
Many of the software issues that happen with Android phones are related to third-party applications that you downloaded and installed. If you had recently downloaded or updated an application before the error message started showing up, uninstall the app and see if that was causing the problem. In some cases, you can reinstall the app at a later time without problems, but in the case of bad apps, you will encounter the problem again if you download it again.
Updates
There are a number of firmware and software updates that your phone needs in order to function properly. Check to make sure that you have your phone fully updated to see if that solves the problem. Applications that need to be updated could also be the cause of the Emergency Calls Only message.
Check Your Phone’s IMEI
Problems with the IMEI number are extremely rare, but it’s worth checking into if nothing else has worked so far. If your phone’s IMEI is not correct, it can prevent you from making phone calls. To find your phone’s IMEI number, open up your dial pad and dial in *#06# which should cause the IMEI number to pop up automatically.
You then need to compare the number on the display with the printed number on a sticker which you can find either under the battery or in the SIM compartment. Since that usually requires you to remove the battery, be sure to write down the number on the display before removing the battery. Sometimes, the displayed IMEI number has a couple extra digits when compared to the printed number, but the numbers should match up until that point.
If the numbers to not match or you keep getting an ERROR message when trying to pull up the digital number, then this indicates a serious defect and the phone is not being properly identified by the network and is therefore not in service. This type of defect does result in needing to have the phone replaced. The good news is that this problem is usually covered by a warrantee. Again, this is something that happens very rarely, but if nothing else is working, it’s worth looking into.
On rare occasions, a bad app will cause a glitch that leads to your phone having no service. Unfortunately, if that app has already placed a bug or virus on your phone, deleting the app itself does not solve the problem. Although viruses for the Android operating systems are not common, it is important to keep in mind that phones are small computers and do need the occasional maintenance.
To completely clear the phone of viruses and other malware that might have made its way onto your phone, you will need to do something called a hard reset or a factory data reset. This will reset everything on the phone and return it to its default factory settings. While this is great for removing glitches and viruses, it also erases all of your user data, so make sure you backup all of your contacts and other information before beginning the hard reset so that you don’t lose anything.
How you perform the reset will vary slightly depending on the type of phone you have. On some phones, you will have to go through “Settings” and then “Privacy” to find the “Factory Data Reset” option. Others require you to go through “Settings” and then “SD and Phone Storage.” Once there, the phone will warn you about losing all of your information.
If your information is safe, then you are free to proceed with the factory data reset which your phone will do automatically. It will power down and may take a few minutes to start back up. When it does start back up, you will usually have to redo all of your phone settings and can begin putting your user information back onto your phone.
Additional Tips and Tricks
Here are a few more tips and tricks that you can try when you have an Emergency Calls Only message on your phone. Many of these are not permanent solutions, but they may help get your phone working long enough to make a call or send a text while you work on finding a more permanent solution. Despite the low chance of these being permanent solutions, they might help you anyway.
Airplane Mode
Sometimes, by turning your phone’s “Airplane Mode” on and then back on will get it to reconnect to the network again long enough to make an actually phone call.
SD Card Trick
SD and other memory cards hardly ever cause problems with cell phones, and even more rarely cause problems that are network-related. However, since they do occasionally mess with your phone, it is something that you can easily check to rule out as a possibility.
Begin by turning the phone off. Then, remove the memory or SD card and turn the phone back on. Test the phone to see if you are able to make normal calls of if it is still displaying the Emergency Calls Only message. If the phone does work normally after that, you can double-check that this was the problem by putting the SD card back into the phone and trying again.
Prepaid Phones
If you are using a prepaid phone or have a prepaid phone service, then you need to be sure that you still have days or minutes to use. Most prepaid phones that no longer have usable time or money will display the Emergency Calls Only message because they can only be used for emergency calls at that time. While these can make great emergency phones to leave in your vehicle, if you want to use them as a regular phone, you do have to recharge and pay for regular service.
How to Contact Your Service Provider
Once you have gone through this entire list and had nothing work, including the factory data reset, the problem is likely network-related and nothing you do to your phone will help in this case. Sometimes, this just means a problem with a nearby tower, but other times, it could be a problem on your account or a specific phone line on your account.
Call the customer service number for your wireless service provider and explain the situation to them. Tell them what happened and what you did so far to troubleshoot. Make sure you have your phone with you while you are on the phone with them so you can work with it as they talk to you, and be ready with your phone’s IMEI number.
While calling customer support can be frustrating, it’s important to be patient as they work to solve your problem. You may find yourself getting bounced from one department to another as they need to check or change different parts of your account settings and find out about your warrantee options. Try to remain patient and polite throughout the process since it is difficult for them to troubleshoot over the phone if the solution is not obvious.
If you are sure that the problem is network-related, then try to remain firm that the problem is on their end to avoid them simply sending you a replacement with which you encounter the same problem. Sometimes, your best chance of getting the problem worked out without getting passed around from department to department is to go directly to a store to talk to a representative there.
When you go to a store, you may find that the representatives there are not the best at troubleshooting, but they will be able to help you rule out some possible causes of the problem such as the SIM card. They will also have a much better chance of getting the right person on the phone if they need to call support for more answers.
As you talk with the representative, be polite and reasonable while you remain firm. If possible, don’t leave the store until your problem is solved or they are clearly actively working on it, such as when a replacement part is being sent to you. In the cases of replacement parts being shipped, always be prepared for the possibility of that part not being the issue in which case you may have to start the process all over again.
Conclusion
When you have a phone that keeps losing service or has the Emergency Calls Only error message coming up, it can be extremely frustrating because there’s no point to having a phone that can’t make and receive phone calls and text messages. It is also hard because if you’re like most people, you use your Android phone for a number of things other than calls and text messages. Hopefully this guide was able to help you troubleshoot your phone and get it back up and running normally again.

Unlocking a phone with UnlockCode4U implies that you will use it with any service provider, no strings attached.
It is a good incentive to optimize your expenses when you choose the company that is most convenient for you.
However, you must remember that if your phone has something pending with the original network provider, you will need to resolve the issue with them so that your phone is working once you unlock it.
Unlocking through UnlockCode4U does not eliminate this type of IMEI block. Additionally, this blocking can be activated by the original carrier in case of losing the phone, lack of payment or phone theft.
This IMEI block is an additional security mechanism. It is only removed when the original owner of the phone clears the situation with the phone company.
A common sign of IMEI blockage is that your phone allows you to navigate the internet and send SMS, but does not allow you to make phone calls. In some other cases the phone will only be useful with WIFI.
So does UnlockCode4U unlock your blacklisted phones or not?
Yes, but it does not eliminate the IMEI block. The phone will be unlocked to be used with any network but it is imperative that you speak with the original network provider, that you pay any pending balance, or that you resolve the phone loss/theft situation.
When you eliminate this IMEI block the phone will work permanently and will remain unlocked.
UnlockCode4U is a transparent and secure company whose object is to improve the user experience with everything related to mobile phones.
For this reason, we try to keep you updated with everything relevant, on top of taking care of your phone’s health.
