Hi 
my mum recently gave me her iphone 4 while she got the iphone 5 as an upgrade , ive never been on vodafone before but since i got a new sim card its been rubbish! I can only get signal in my house when im connected to our bt thing , when im out i cant do anything , surely there must be a way where i can get signal wherever i go?? When im at work on my break i want to go on my phone but it doesnt work , can someone help please?
