Sorry to hear about your problem.
Have you tried your default code i.e. 00000000?

Best Regards

Yes, I did try(NNN) NNN-NNNNbut it doesnt work. I changed it and like I said before I forgot it. Also its only 4 numbers.
Expert:  PramitP replied 8 years ago.

Here I am giving you the second option. Try this.
1. Remove SIM card and switch on the phone.
2. Using the keypad, enter *2767*3855#.
3. Wait for 10-15 seconds.
4. Phone will reboot and the settings will be resetted to factory settings again.

If they won't work then you have to go to your service provider as they will be able to give you the unlock code.
If you need any assistance then I would be glad to help you.

Kind Regards.

It is a Sprint phone there is no sim card. Does that matter?Theres one more thing. A prompt pops up if, I try pressing send saying "Emergency or special dialing only". I don't know if that helps any!Laughing

Sorry for the late reply Ma'am.
I don't think it is possible to unlock a CDMA phone.
But I would suggest you to try it first and then inform me what happens.

Note: In my previous post please mark Step 2.
I would like you to type in *2767*637# XXXXX of *2767*3855#.
I am sorry for typing it wrong in the previous post ma'am.

The Emergency call is meant for special numbers only like 911.

Best Regards.
Good Luck
