What's the deal?

The T-Mobile Network Test Drive app is an iOS only based app that gives potential customers using a compatible unlocked iPhone the option to test our amazing network out before joining. T-Mobile Network Test Drive offers you up to 30 days or 30GB of high-speed data along with unlimited talk and text for free, all while keeping your current carrier and phone number. This gives you the ability to try our network on your iPhone, risk free.

  • Use your current phone and phone number.

    • Once the trial expires, you will not be able to keep the temporary number that you were assigned.
  • At the end of the trial, your current provider remains active on your device and the deactivated T-Mobile eSIM profile can be safely removed.
  • You'll receive emails and text messages from T-Mobile throughout your trial to notify you of instructions, and status.

What's an eSIM?

Embedded SIM cards (eSIMs) are SIM cards built into the device. If the manufacturer allows it, they may also support multiple profiles.

What's cool about eSIMs?

  • eSIMs can be used in multiple devices such as tablets, watches, IoT, and smartphones.
  • Smartphones with eSIMs can support multiple profiles that can be downloaded and changed as needed. You can have two lines from the same provider or different ones!
  • A physical sim is not required in order to use a device's esim.
  • A profile defines all the settings to connect to the T-Mobile network. We identify a profile by the ICCID and pair it to the device EID.
  • For devices that support multiple eSIM profiles, such as Dual SIM with eSIM, only one eSIM profile can be enabled at a time. Not all eSIM smartphones can support multiple profiles.
  • 5G compatible devices with eSIM will also receive the benefits of 5G if customer's choose to use their eSIM profile on the device.
