There are very few reasons why a code will not work.
1: The IMEI submitted may not be the actual IMEI of the phone.
Sometimes the IMEI was simply entered wrong, you may have assumed that one code would work with all phones within a certain make or model. Each phone has an IMEI, and each IMEI has unlock codes that are based on a combination of the make, model, carrier, and sometimes the edition. For instance, some Alcatel phones have one of 8 different “PRD” numbers that effect the unlock code delivered to you.
The best thing to do is to be absolutely certain that the IMEI is correct by dialing *#06# and comparing this to BOTH the IMEI on the back of the phone, or one a label under the battery, AND ALSO comparing that to the IMEI number that you ordered. If all three are the same, then most likely it’s a different issue requiring a factory reset.
Sometimes the IMEI is faked to attempt to overcome blacklisting. And sometimes the IMEI entered was from the hardware, when in fact the circuit board was switched out by a phone repair company.
This may have been done by someone other than you, so it’s best to simply back up all of your data and perform a factory reset, so that everything is erased, and the software on the phone is exactly the way it was the day it left the factory. You can either search Google for factory reset instructions, ask your new carrier for help, or ask our 24 hour live chat team to help you or if they don’t have the information, they can open up a support ticket for you.
2: The phone may not be using original factory installed software.
Sometimes people will “hack / crack / jail-brake” their phone in order to add free versions of paid apps. This may have been done by someone other than you, so it’s best to simply back up all of your data and perform a factory reset, so that everything is erased, and the software on the phone is exactly the way it was the day it left the factory. You can either search Google for factory reset instructions, ask your new carrier for help, or ask our 24 hour live chat team to help you or open up a support ticket for you.
3: Sometimes the phone just isn’t responding correctly.
It could be something as simple as needing a reboot, or simply freeing up internal memory to allow the appropriate update. If the phone has liquid damage (even from a steamed up room) then you may have other issues with your phone that are not related to the unlocking process, but are preventing you from completing the unlock. If this is the case, then be sure to take it to a cell phone repair shop, ask them to inspect your phone for liquid damage, and see if they can have it cleaned for you. Once you have it repaired, then back up your personal data if you haven’t already and perform a factory reset.
In most cases, a “factory reset” will correct the issue. This factory “hard reset” will bring the phone back to the condition it was in the day it was originally unboxed and activated. Be sure to back up all data and contacts before resetting your phone.
Here are some other reasons.
1: The phone was never activated. In some cases a phone is purchased and never activated, or it simply disappears from a stores inventory and for one reason or another, is not reported as stolen. If a phone has never been activated, then most likely, it can not be unlocked, because the activation must happen first.
2: The phone has a PERSONAL SIM PIN LOCK in place. The PERSONAL SIM PIN LOCK is a 4 to 8 digit pin code that has nothing to do with the Carrier / Factory “SIM Unlock” we offer. Our service is only to help people move from one carrier to another by providing a carrier / factory unlock code.
A PERSONAL SIM PIN LOCK can be placed by a phone’s owner, in order to make the phone useless if it is lost or stolen. It locks the phone to the SIM card that is in it, and if that SIM CARD is removed or replaced, the phone will not work.
Since the SIM in the phone is “PIN CODE” locked by that customer to their account, then someone who found or stole a phone, will not be able to use it, and vice-versa. Older phones may have a default pin. The default PIN CODE for a number of phones is usually 1111 or 1234.
However, be warned. If someone enters the wrong PIN CODE too many times, they will get an error asking for a PUK code.
The PUK CODE (Personal Unlock Code) is only available from the carrier of the original carrier, or the carrier of the person who set the PIN CODE. If you are unable to get a PUK CODE, you can try a factory reset, but most likely that will have no effect and the phone is essentially “BRICKED.” If you enter the wrong PUK Code too many times (often 10 times) then the phone is bricked to that SIM, and the account holder of that SIM will have to get a new SIM card from the same carrier.
What’s next? – It is possible to sell it for parts for a fraction of it’s original price. Likewise, it is possible to unlock it through a USB cable with the right software. We don’t provide that service, and the best thing you can do is to take it to a cellular phone repair store and ask them for help. Just be sure to explain that you have multiple types of unlocks that you need for your phone, and not just the carrier / factory sim code.
3: In some cases a phone is HARD LOCKED. This is extremely rare with major carriers. The only carrier that has sold hard-locked phones recently is TRACFONE, which also owns a variety of other brands such as Straight Talk, and Net10. The FCC has ruled that this process is no longer legal, so people who have hard locked phones should be able to return them for credit or a replacement by contacting their original carrier.
4: The phone is APP locked.
So far, only a few phones are app locked.
If your T-Mobile or MetroPCS phone was purchased new from a retail location after July of 2015, then most likely your phone requires an APP unlock.
If you are receiving an error such as “Server Not Responding” or “Device Not Eligible” while using your MetroPCS Device Unlock App, then be absolutely sure of the following:1: Be sure you can connect to Wi-Fi within the U.S.A.
The best way to tell, is to turn off your data, and then try to go to a random web page through a search on Google. If you can, then try the App again.2: You may need to restart your phone.3: Sometimes servers are just busy, or have not yet updated completely.This can be because the server just has too much activity at one time, and other times it is simply because the server needs maintenance. Simply try again in a few hours, and most likely the problem will resolve itself.
4: If the problem continues, then your IP address may not be connecting properly.
According to MetroPCS, if you have a “Server Not Responding” error, then “please try an alternate internet internet connection.”
