I Just topped up £5 on my Vodafone pay as you go. I wanted to buy a game for £3.06 But when i pressed "Buy" my phone said it don't have enough credit WTF? I think it has somthing to do with the price of the internet per minute. So i want to ask. Where can i get a Vodafone sim card that can give me FREE internet so i dont run low on credit. thank u.
