Using the iPhone 4 with AT&T as a GoPhone

Updated: October 15, 2010





Who is this guide for?
  • iPhone 4 owners (activated or not)
  • 4.0 or 4.0.1 firmware (all features)
  • 4.0.2 (no FaceTime, MMS or tethering)
  • 4.1 firmware (all features)


If you read my other article on using alternate SIM cards in the iPhone 4, then you'd know I was able to purchase a GoPhone and use the SIM to activate a freshly restored iPhone 4. While you can do this and also have a data plan that uses 3G all without being jailbroken, you gain the ability to use FaceTime, MMS, and tethering if you do jailbreak. Visual Voicemail is only for those under contract so you will not get this feature.

If having an expensive contract with AT&T is not for you, then this is the tutorial for you! This all came about when I received this text message not long after activating my iPhone 4 with a new GoPhone SIM card.

There are two methods for activating (and I don't mean just getting past the emergency call only screen, I mean receiving the actual iPhone is activated message) the iPhone with a GoPhone SIM:
  • You use an active (with working phone number) SIM from another AT&T account to activate your iPhone. Doing this will allow you to use your GoPhone SIM in other phones besides your iPhone right away.
  • Not having acces to another AT&T activated SIM, you use the GoPhone SIM to activate with, and your iPhone is bonded to that SIM for an unknown period of time (I've read six months).

Step 1.

Once you have your GoPhone SIM, cut it down to micro SIM size and place it into the iPhone 4. You can even do this from the slide for emergency screen. After a few seconds it will activate. It is best if you have your iPhone plugged into iTunes during this process.

Don't be misled by the 3G icon appearing, you don't have 3G connectivity yet. Even if you go into your network settings and turn on 3G and cellular data, you still won't be able to load a webpage.

Step 3.

Connect your iPhone to your Mac via the USB cable. The iPhone Configuration Utility will be installed in your Mac's Applications/Utilities folder. Launch it. Here's the default screen. Note: I've blurred out a lot of personal information.

Go to the Devices menu and click on your iPhone. Look to the right and click the Configuration Profiles tab. You should see the profile you just created. Click the Install button.

Step 4.

Your iPhone will now prompt you to install the profile you just created. Press the Install button. Then press Install Now.

Once it has finished installing, press the Done button. If you go to Settings and press General you'll see a new menu there for Profile.

If you want to remove this profile just press the Remove button. Launch Safari and it will connect to a website on 3G!

It is very important that once you are done surfing you shut off your 3G and cellular data services or it will bleed your account dry!

I noticed the next time I synced with iTunes I was prompted with this.

Step 5.

If you want FaceTime, MMS and tethering to work, then you must complete this tutorial: Tethering (without a tethering plan).
