Does anyone have the same problem? I have received instructions from T-mobile USA with the Sim unlock code. I never see the "P" or "w" displayed when i enter these instructioins:
1. Press # (pound)
2. Press * (star) three times = P
3. Press * (star) four times = W
4. Press * (star) twice = +
5. Enter the unlock code
6. Press * (star) twice = +
7. Press 1 (one) = 1
8. Press # (pound), phone should display "SIM Restriction Off"
Does the 3650 need to be in a certain mode? I've tried it with another carrier sim card, but get no response. I believe the phone thinks I'm dialing a phone #. No error message, etc.
After screaming at T-mobile USA and Nokia support. I discovered that "KeysticK App" was the reason I didn't see "P" and "w" when entering the commands for sim unlock. If all else fails delete all your apps and work backwards.
