I recently stumbled across a very interesting article on HubPages , written by info4all. The article, titled “Secret iPhone Service Codes,” provides a short list of some of the “codes” Apple and AT&T have integrated into the iPhone, allowing phone service information to be accessed using the phone application’s keypad.
To use these “codes” (if they can be called that,) open up your iPhone’s keypad, and type one of the codes listed below. Hit the call key to execute the command.
Basic iPhone Information
Use these shortcuts to view information about your iPhone’s core functionality:
*3001#12345#* : Enter Field mode. Field mode reveals many of the inner settings of your
iPhone, specifically up-to-date network and cell information.
*#06# : Displays your iPhone IMEI, the unique identifier for your cell phone hardware.
(No need to tap Call.) Together with your SIM information, it identifies you to the provider
These shortcuts provide quick access to information about your account:
*225# : Bill balance. (Postpaid service only; the acronym is BAL for balance.)
*777# : Review account balance for prepaid iPhones on the GoPhone plan.
*646# : Check remaining minutes. (Postpaid service only; the acronym is MIN for
*3282# : Check your data usage. (Postpaid service only; the acronym is DATA.)
*729 : Make a payment. (The acronym is PAY.)
611 : Connect to customer service.
While you can undoubtedly use your iPhone to its fullest without ever having to enter one of these codes, I just thought it was pretty cool that items such as bill balance can be accessed straight from the iPhone.
