Several iPhone 3G users have reported an issue in which their own numbers are not displayed on the devices. Generally, the subscriber's own number is displayed at the top of the contacts list (above the search function). The simple answer to this issue: the number was never properly saved to the iPhone's SIM card.
This problem can be solved in one of three ways:
- Insert the SIM card in another phone (such as a Motorola RAZR) that allows you to manipulate SIM card contacts directly and enter your number.
- Call AT&T customer support at 1-800-331-0500, explain the issue, and ask them to send you an over-the-air SIM update with your number.
- Go to an AT&T store and ask them to program your SIM card appropriately.
