- Order a Starter Kit: You have already completed this step by acquiring the kit.
- Universal SIM: The included SIM cards are 3-in-1, meaning they can be adapted to fit standard, micro, or nano SIM slots. Carefully punch out the correct size for your device. Newer phones may support eSIM, which US Mobile also supports.
- Activate your SIM: Download the US Mobile app from your device's app store or visit usmobile.com/activate to activate your line. You will be guided through the process of selecting a plan and setting up your account.
- Insert the SIM: Power off your phone. Locate the SIM card tray, usually on the side of the device. Use the provided SIM ejector tool (or a small paperclip) to open the tray. Place the correctly sized SIM card into the tray, ensuring it is oriented correctly. Reinsert the tray and power on your phone.
Once inserted, your phone should detect the new SIM card and connect to the network. You may need to restart your device after insertion.
