3g not working on my iphone 4?

3g is turned on in my settings, I have the 3g sign in the left hand corner. But every time I go to get on the internet it says it can't connect to server. Can anyone tell me what I need to do to fix it? I have tried just about everything.rebooting it and resetting network settings and nothing seems to work… Please help.

Added (1). How am I going to use all of it if it won't let me use it? The only time I can use the internet on my phone is when I have Wi-Fi.

Maybe you used up all your data

Have you tried a hard boot? Removing the battery while its still on? Call tech support. It may be an issue in your area with the 3g network. I worked for ATT and we would get so many angry calls from those who bought a 3g phone but the 3g would not work. It was because most were NOT in a 3g area. So they would blame us saying why the hell are they paying for a service then that doesn't get 3g? I told them that they are paying for the same package and price 2g gets, it was their choice to buy the 3g phone.

If its not being able to connect to the server, perhaps it is the website that is down from a simplified perspective.

Otherwise, try turning on airplane mode for a while, then off it again. If not, maybe the signal in your area is too weak to properly connect to the web.

  • TWITTER NOT WORKING ON iPHONE So, everytime I go to the home page on twitter, on my iPhone, it says, "Error loading tweets (400) tap to retry" it was working perfectly fine before, so why is this happening now? Even when I try going to people's twitter pages it doesn't let me see their tweets, or who they follow. I tried deleting the app and re-installing it again, but it still pops up like that.
  • Switching from 3G to 4G, Internet not working.iPhone 4S? I had an iPhone 3G with Rogers pay-as-you-go plan then I recently upgraded to a 4S. My data plan seems to work fine with making calls and texting, but the Internet won't work at all, just says it can't connect? Do I maybe need some sort of 4G plan?
