AT&T GoPhone SIM for iPhone 4S? Would be appreciated?

I just ordered an AT&T GoPhone SIM card from Walmart.com. It will arrive in a few days. I plan on using my iPhone 4S as a go phone. I already know how to cut it when sissors. But I heard that once you activate the SIM, there are many "Hoops" to jump through to get the 3G Data working. What do these hoops mean? How do I get the 3G Data working?

Take to a radioshack ask if they can activate or to att… If done right through att system should work fine

Unlockit.co.nz its very simple to use all you have to do is pick the carrier an select it

I think the 3G/4G can be activated by creating the custom APN settings. Here is the link on how to do it.

  • Will my ATT gophone sim card work in a old iphone 3gs? If i buy an unlocked ATT iphone 3gs off of ebay can i put my att sim card in the iphone and make calls and such
  • Will att gophone sim work in iphone 4? I'm looking into buying an iphone 4 but I have a question before I buy it. If I cut my ATT gophone sim card to a micro sim will it work in the iphone 4 the same way it worked in my gophone?
  • Prepaid gophone sim card in iphone? Okay so I have an iPhone 5S, I previously had an old iPhone 4. I will be giving away my old i4 to someone who is currently phoneless, so my question is if I buy a prepaid phone from AT&T and try to use its sim card in the old AT&T iPhone 4, would it work? Or would the phone still need to get unlocked before any other sim card is able to work in it.
  • I accidentally got in the pool with my iPhone 5. All help appreciated? Is it better to just get a new iPhone preferably another 5 or 5s, or get the water damage repaired? Is one option cheaper or better than the other?
