I basically lost my phone and had to order a new sim (i'm on contract)..
soo I bought a new phone samsung u800 locked on t-mobile..
But when i use my virgin sim in the phone it keeps saying "call failed" when ever i attempt to make a phone call.. It is picking up a signal.. and im utterly clueless as to why it isn't working..
Anyone have an idea??
Also i recieved the sim this morning and it still ain't working...
any help is much appreciated! :)
