Replacing your old device with a new one is pretty simple. Open your My Vinli app, tap menu, then tap My Devices. Tap on the device you are replacing, scroll to the bottom and tap Replace Device. Locate the 7-digit Case ID found on the back of your new device and enter it at the prompt. Then tap Continue. That's it. All of your historical vehicle data has been transferred over to your new device and it's ready to be plugged in to your vehicle.
If you are a T-Mobile account holder, once you tap Replace Device, you will be promoted to call T-Mobile in order to change your SIM. You will need both the MSISDN number and the SIM number displayed on this message to continue. Once T-Mobile confirms the activation, your new device will appear under My Devices.
