eSIM, short for Embedded SIM, is a digital version of a traditional SIM card. With eSIM, there's no need to wait for a physical SIM card as you can simply download it over Wi-Fi. It allows you to connect to the T-Mobile network within minutes, providing a convenient and efficient way to activate your device.
Apple iPhone:
During the initial setup, you will be prompted to activate an eSIM. If you have already set up your iPhone and are connected to Wi-Fi, your iPhone will notify you when the T-Mobile Cellular Plan is ready to be installed. If you didn't receive a prompt or chose to activate later, you can activate your eSIM by going to the device Settings > Cellular.
Samsung
During the initial setup, you will be prompted to activate an eSIM. If you have already set up your Samsung device and are connected to Wi-Fi, follow these steps: Go to Settings > Select Connections > Choose SIM manager > Tap on Add eSIM to initiate the activation process.
For Google Pixel 7 and Pixel 7 Pro devices, ensure that you are connected to Wi-Fi during the setup process. You will be given the option to download your eSIM. However, for other Google Pixel devices, you will need to insert a physical SIM card.
