[Android Central Question]

My phone says SIM card perm locked-no service. I purchased a code to unlock it, but my phone wont do anything. There isnt a way to enter a code, what do i do?

Welcome to Android Central! Are you talking about the SIM card itself, or is the phone blacklisted? If the SIM is locked, then contact your carrier. Maybe you just need a new SIM. Or is the SIM actually password-locked? If so, then did you just get it from someone else? It's possible to put a lock on a SIM, so if you didn't put the lock on, you might not be intended to use it.

Try to use another SIM to check if the problem persist.

Also, you could check on Check IMEI number / ESN - free checker IMEIpro.info if your device is blacklisted.

And I would also add that you should check if your device SIM counter is zero. If it is, then you can't unlock your phone.
