Ok so, my mum used to have a Samsung Galaxy S2 and then she got a Samsung Galaxy S4 when her contract ran out. She got a new SIM so I used her old one in my iPhone 4 and it worked. My dad gave me the £10.00 goodybag from GiffGaff which includes 1GB of internet. Whenever I am at home I always use Wi-Fi but I wanted to use my 1GB of internet whenever I am in the car or somewhere that doesn't have Wi-Fi. I thought whenever I would use the internet and I wasn't connected to Wi-Fi, it would automatically start eating up my 1GB of internet but that doesn't happen. Whenever I am not connected to Wi-Fi and search something on the internet my iPhone says, 'You are not subscribed to a cellular data service.' Do I have to do something settings? How can I use internet on my phone? Help!
