Hello Djnyc2468,

Well your best bet is to contact your service provider the one whom originally provided service for your phone (AT&T).

They will have to help you unlock that phone as that model is not covered by the cell phone unlocking program that I would normally use to generate a code.

If its the new tmobile sim card that has been blocked you will need to contact Tmobile to help unlock it.

Post back if you have any further question's or comment's. I will be happy to assist you further. Thank you for choosing Fixya!

This password or pin is unique and should be kept secret and should never share it is burned inside the chip by the company like Tmobile that issue it. For you the best approach is to contact Customer Service of Tmobile and explain them everything they are the only ones to help you.

you actually need to unlock your phone to use the simcard not just a code. boost mobile and tmobile run and different networks to its not as simple as putting in a different sim card.

It doesn't recieve or deliver mms I have t mobile


im really sorry about that! i have delt with this issue myself. alot of times it can be an issue on tmobiles side. if the phone is unlocked (i.e. not a tmobile phone) you need to get the mms settings or apns from tmobile. if it is a tmobile phone delete as many sms & mms as you can memory can cause major issues. if you have deleted all your messages and you have turned your phone on and off (if it is a tmobile phone) call tmobile and let them know. 9 out of 10 times its just a setting on the network and your be up and running in minutes! i hope this helps!!!

The Nokia is locked to the Tmobile and you must get teh unlocking codes from your Service provider to allow it to use other networks.
So call your toll free service provider 's call centre.

I don't know the service provider


You would need to unlock it, so that it works with any network. Problem is It can't be done over the internet for that model. You would need the dongle and software to hook it to, so you could generate an unlock code.

There is one known process you can try but don't give your hopes up.

==UNLOCK TO NETWORKS==
Unlock service provider: Insert sim, turn phone on and press vol up(arrow keys) for 3 seconds, should say pin code. Press C,then press * message should flash, press * again and 04*pin*pin*pin# \
*#7328748263373738# resets security code.
Default security code is 12345

Good luck and thank you for trying Fixya!

This will also bring the phone to default settings 1. First do a CUSTOM reset: *2767*2878# (star 2767 star 2878 hash)
turn off the phone 2. take out the battery and sim and put wrong network SIM and insert a half of it,
so it won't ask for network password and shows "Insert SIM" message.
Now put the battery ,and switch the phone on .(phone shows "Insert SIM" message.) 3.With out turn off the phone push the sim fully in. At this stage the phone is still asking to "Insert SIM" 4.

Believe them. If there is a network issue, then a tower may be down and cause signal problems.

One solution requires you to call in, ask for PDA support and have them refresh you on the network.

You must contact tmobile with the phones information. The sim is registered but Network does not reconize your phone as an authorized device.
