Nokia troubleshooting instructions:

For AT&T Nokia Lumia 900 Invalid Code Message:
If the Unlock Code provided is asking saying error, please continue to enter the unlock code provided until the phone asks for the “PUK” code.  Please do not worry about the attempts remaining.  Once you have diminished all your tries, the phone will ask for the PUK code and this is where you enter the Unlock Code

Your Nokia phone displays “Code Error” or “Sim Network Unlock Unsuccessful” after inserting the unlock code

Never enter more than once the Nokia unlock code,if you know you wrote it correctly but was not accepted.

If the code is not accepted do a factory reset and try to reinsert it. If you have a custom firmware that might be the cause why is not accepted so should restore to stock firmware and try again.

If still not working contact us and will send you a program to insert the Nokia unlock code using that, or will insert it online for you.

The Nokia device asks for  “Sim PIN”  or “PUK”

Those are codes specific to your SIM card and should be written on your SIM package if is a new SIM.The SIM pin is either set by the Sim owner or if is a new card should be written on the SIM instructions papers. For most Sim cards the default PIN is either 0000 or 1234 ,but you only have 3 tries so would recommend to try finding the exact Pin before trying those.If asks for PUK you can find it by calling to your carrier support or look on the original SIM package.

Your Nokia asks for  “Phone Password”/”Security Pin”/”User code” or another user lock like pattern lock/Gmail account

Most likely your Nokia has a user lock. To be sure that’s the problem turn on the phone without a SIM inside or with the original SIM. If asks the same thing then for sure the user lock is the problem.  The fix for this is a hardreset.

After turning on your Nokia smartphone with the new sim inside it displays “No SIM”

It means the Nokia mobile cannot detect the sim card at all.The most usual reason is that the SIM card is not inserted correctly, so verify what’s the right way to insert the SIM card and reinsert it.If you still you get the same message there may be a problem with your SIM card, either SIM is broken or not supported by the phone at all , so verify if you get the same message with other SIM  card or there might be a problem with the sim card reader.

The Nokia phone accepted the code but still displays “No service”

This can be caused by many things, here are the most common reasons :

-The SIM card is not registered, not activated or not supported by the phone. So should either try with other SIM, or should verify to see if this SIM works in another phone to exclude this possible issue
-Your phone can be blacklisted because was declared lost/stolen or for not played contract. To verify if that’s the problem try with the original sim to see if works or contact the network help service. If the phone works fine with the original SIM that this is not the problem
-A settings or firmware problem. Can fix that by selecting the network manually ,doing a factory reset, update or firmware restore
-The phone has a hardware problem. If any of the above fixes do not work your phone may have a hardware problem and should send it for repairs, hopefully using the warranty if still available
