Activating service with eSIM
Activating with eSIM is a great way to bring over your own device to experience T-Mobile's 5G network. Begin your journey here:
- On your computer or device, go to prepaid.t-mobile.com and click the banner to activate service with eSIM.
- Follow the steps to check for device compatibility by selecting which make and model of device you have. When finished, select Continue to plans.
- If you don't see your device listed, select My device is not listed and then select Get a SIM Card.
- Your device will require a physical SIM card to activate service. Follow the additional screen prompts to begin activating your T-Mobile service with a physical SIM card.
- Scroll and select from the list of available Prepaid rate plans. When finished, select Continue to payment.
- Enter your personal information (name, email, zip code, payment method), then select Continue to review.
- If your email is already in use with a T-Mobile account, you'll need to use a different email.
