• The PUK (Personal Unblocking Key) code is entered incorrectly multiple times. This can inactivate the SIM card. If inactivation appears to be permanent, contact your operator or service provider for a new SIM card.

Helpful?

if you are getting this error then that means may be you bought new sim and the sim is not activated. It will done by dealer. Or your sim is inactivated.

Check your Band setting on your phone. 900mhz/1800mhz or 1900mhz/850mhz

just change the sim card,

A. Turn on phone with full battery and non-T-Mobile SIM in place.
Allow phone to completely boot up to Wrong SIM screen. B. Enter from Wrong SIM Screen *#7465625# to confirm lock status C. Scroll through Interrogate Screen 1. Network lock - Active (this is the one you'll be deactivating)
2. Subset lock - inactive
3. SP lock - inactive
4. CP lock - inactive
5. SIM Card lock - inactive
6. Activa lock - inactive
7. Auto network lock - inactive

10. Auto CP lock - inactive
11. Auto SIM Card lock - inactive

screen E. From the Wrong SIM screen enter the following: *7465625*638*00000000*00000000# Those are two series of eight zeros. The phone will not show the zeros but will show dashes in their place. Phone may make a small tone and at the bottom of the screen it will read "Network Personalized" or perhaps "Network Already Personalized" F. Now input the following from whatever screen shows up: #7465625*638*00000000# (again this is a series of eight zeros) Phone may make small tone and will read "Network Lock Deactivated" G. Turn off phone

That's it. Your phone is ready to accept SIM cards from just about any GSM mobile telephone service provider in the world. If you received a "wrong password" message you will need to insert a working SIM and reset the password to the default 8 zeroes "00000000". After that you may try this process again and it should work.

I have the same problem, i have tried putting the sim card into another phone on that network, and swapping it back, and it does work, but not for very long! :(

inactive sim means the sim is disconnect or need to be activated so call your mobile service provider and have them assist you with the issue.

you gotta wait for your provider to activate it if nothing it 2 days call them with your dilemma

u shuv it up ur ***!! thats wat i done it now works :D
