hi,

i have a nokia 5110, version 5.22, which came with my car, as a car phone.

the problem is it wont work when i put a t-mobile sim card in?

it just says no network coverage, but
when i put a vodafone or O2 card, it works...

i tried using the free unlok software, but every code i have inputted just shows a message saying "sim card was not restricted",

can anyone please help?

thanks
