hey ppl,
kinda new to all this,i have recently bought an iphone 4
,i went to an o2 shop and got a micro sim and swaped my old number onto that online,since then my old sim card has no service,and my micro sim will let me browse the internet and app store (with out a wifi conection),but i cant make or receive calls or texts messages,any help would be great.
thanks, mike
