Apple Watch Ultra 3 won’t work on Verizon LTE?

I have US Mobile using Verizon‘s network. Although they offer an Apple Watch plan, the ultra three doesn’t seem to work because Verizon‘s network is only LTE for watches. I thought the ultra three would do LTE or 5G. Does anybody know what’s going on with this? Is anyone else having this problem?

US Mobile is NOT a supported cellular carrier for the Apple Watch. It doesn't matter if they are using Verizon's network or someone else's. US Mobile is NOT the same as Verizon.


If you want cellular service on your Apple Watch, you will have to switch your phone and watch to a supported carrier.


You can find a list here: Apple Watch - Carriers - Apple


Note that US Cellular is a supported carrier. US Cellular and US Mobile are NOT the same company.
