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
- 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).
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.
Download the iPhone Configuration Utility 3.0 from Apple here: http://support.apple.com/kb/dl851
You should now have this file on your computer. Double click it.
Double click the pkg file.
Continue with the installation process.
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.
Under Library, click the Configuration Profiles entry. Click the New button in the top left
Click the General icon toward the middle of the screen. Enter information for the name, identifier,
organization and description.
Scroll down to the Advanced icon and click it. Then click the Configure button toward the right.
Go to the Access Point Name field and enter wap.cingular Go to the Access Point User Name
and enter WAP@CINGULARGPRS.COM Go to the Access Point Password field and enter cingular1
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.
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.
If you want FaceTime, MMS and tethering to work, then you must complete this tutorial:
Tethering (without a tethering plan).
