No 3G after purchasing a new plan?

I have just recently bought a new plan for my iphone 4 that includes unlimited talk, text, and web but when i put in the new sim card and wait for a few hours, the 3G doesn't work.

Gosmart Mobile is operated by T-Mobile. The iPhone 4 is not compatible with the network. It is not possible to get any data speeds higher than EDGE. You also lose MMS and may lose other functions.

  • Why isn't there more space on iPhone after purchasing the extra GB? Last month I purchased an extra 50 GB for my storage. The money is being taken out but there's still no space. The settings shows that I have 48 GB available but I still can't take pics or download apps. Any suggestions?

  • Trouble purchasing apps on iPhone 4s? I recently got an iPhone 4s. Every time I try to buy an app or a song it tells me I need to sign in first. So I put in my password, then it tells me I need to update my payment method. It gives me a list over credit cards to choose from to pay with. How do I pay with the money I have on iTunes?
  • Queston about purchasing an iphone 5c? I have a Samsung galaxy s2 and want to upgrade to an iphone. However my plan is not up yet so I know I would be paying quite a lot of money. Anyway, I have unlimited texts and internet, would that change by buying a new phone or not?
