I have tried many options, but nothing works. I have the 10 pounds goodybag which includes unlimited web, but it doesnt work. im getting so tired of this as giffgaff doesnt response to my email. what do i do? i have a blackberry curve 8520 and when i try to open the internet it says: ''This is a WI-FI service. Please ensure your device has an active WI-FI connection and try again.''
