New sim received for phone (blackberry 9300). After power-up, progress bar shows for "security software verification", then message "Your current sim card requires an unlock code. Would you like to unlock it?"
If enter no then phone works but with "Invalid SIM card" message at top of screen.
If enter Yes, then get prompt "enter network MEP code (n left)"
Entered the 16 digit unlock code from the letter that came with the new SIM, but it is not is not accepted.
I tried the SIM in an old unlocked Nokia, and it appears to work fine (welcome message and be ready for mms activation messages)
Back in the blackberry, still asking for MEP code.
My online VM account shows that they know I have the blackberry, but there's no imei recorded against it.
I've tried the method you've posed elsewhere for unlocking, but the blackberry (qwerty keyboard) insists on converting the initial "#" to a Q when i enter the "p", so I can't enter the code in the format you've suggested.
