First i want to hello i am new here and have a question just recieved new cell phones today from Cingular got the L2 yea cheap phone but free was wondering if I needed to upgraded to the new 3g sim that came with them before i just kept my old sim.
No the 3g card is sim memory and the only advantage I can see you getting is more contacts I would hang on to the card though, in case in the future you lose your current sim, as a new one isn't free.
