Original iPhone as a GoPhone from AT&T

So perhaps my iPhone 4s is no longer operational and am awaiting a new phone, which may not arrive for a couple more weeks.  To fill in the gaps in between I took my original AT&T iPhone and activated it using a GoPhone Sim Card.   No Jailbreak is needed and you can do from the phone and from a computer with web access (or Phone connected via Wifi).   Here is what worked for me.

1.  Buy a 15$ GoPhone generic Samsung flip phone from Wal-Mart.  I bought ATT because that is what the original iPhone (2007) was.

2.  Open the GoPhone and discard the phone and keep the Sim card (looks like a credit card with a little chip that pops out).

3.  Join your iPhone to Wifi and download this file.  Mobile Config (For US AT&T carriers only)

Your phone will ask you to install the settings, just click install and choose okay.

4.  Now put in the SIM card into the older iPhone (Works with Original iPhone, iPhone3g and iPhone 3gs -with older iOS)

5.  Now follow the GoPhone instructions and activate the phone but using the iPhone and using the web to activate instead of the phone.

Start here.  https://www.wireless.att.com/GoPhoneWeb/goPhoneLanding.do?method=activatePayGo

You will find your SIM number on the card that came with the GoPhone.

 

 

 

You will find the IMEI number on your iPhone under | Settings | General | About – then scroll down to IMEI.

6.  Thats it now just save the phone number and put this into your iPhone settings,  Settings | Phone | My Number

7.  Make sure you add money to your go phone account,  can do it through the phone if you reboot it, or can also put money on account via the web.

After you have money on the account, reboot the phone or just wait few minutes and your iPhone is now a GoPhone.

 

Note:  There is no need to jailbreak or modify your phone whatsoever.

Note:  Do not activate the GoPhone Sim in the generic flip phone that comes with the package.  If you do the SIM gets locked to that phone for 6 months and will not work.  You must activate the SIM first with the iPhone or go to AT&T and get a new SIM.
