Quick facts

For an overview of which plans are available, see the Mobile Share Value overview page. For help choosing the right plan for you, use the Planner.

When you purchase a SIM card, you must also purchase a new rate plan and, in some cases, a data plan. A long-term service commitment is not required. All smartphones require data. If you do not add a data plan to a smartphone, AT&T will add it for you upon activation.

To use data services on the AT&T network with a device from another carrier or purchased directly from the manufacturer, you may need to program the data settings. If you are using an AT&T branded device, it should already be programmed with the correct settings. For a step-by-step guide to changing your data connection settings, please visit our Programming non-AT&T devices article.

To find out if your device uses a SIM card, a micro-SIM card, or a nano-SIM card, enter your device and brand, or the IMEI number, above. All versions of the iPhone® 5 use a nano-SIM card. iPhone 4/4S uses a micro-SIM. Most 4G LTE Android™ phones use a micro-SIM.

A SIM (subscriber identification module) card is embedded with a specially programmed microchip that inserts into a compatible Global System for Mobile Communications (GSM) mobile device. The SIM card encrypts transmissions and identifies the user to the mobile network. Without a SIM card inserted into the mobile equipment, only emergency calls to 911 can be made.


No. Like current Mobile Share plans, Mobile Share Value plans do not require a smartphone on your account.
