Oh no! I have a SyncUP Drive myself and I love it. I actually named my Wi-Fi "The BIG truck next to you" that way when someone is looking for Wi-Fi while driving they will look at me haha.
From what it sounds like, the device is connected to your vehicle and it’s getting power as you are able to see the Wi-Fi but there is something going on with its permissions to access the T-Mobile network. Have you ever been able to use the Wi-Fi with this device or has it never worked? If it has never worked, you may want to Contact Us so we can make sure everything is good to go on the account side.
