I didn't apply the update however. Popped in my T-Mobile SIM card and it won't recognize the card. Not sure if I did something wrong or it just doesn't work. Is there a way to unlock the SIM?
I'm soryy but I tought was already clear that the phone must be sim unlocked.
There are two kind of locks on the D3
the sim lock, that blocks any sim different from the verizion one
and the band lock, that blocks the gsm in the US (no matter the sim inserted).
The first kind of lock is easy to remove with a code provided from both verizion (for free if you are entitled) or third party companies (for a price, usually 10$).
The second kind of lock is the one talked about in this thread.
P.S. I'm afraid that if you have the unlock code you must be on the verizon rom to input it.
