This is excellent! I hadn't really considered that the car might get better reception than my phone (or have access to other towers). Since we have AT&T for our phones I was hoping that the Rivian would be on a different network. We have WiFi-calling enabled on our phones to allow us to make/take calls when in VRBO's with internet but no cellular coverage. That should work in the R1S too!Multiple factors here -
I frequently use the car's wifi to get service when my phone is at the ragged edge of reception, it's quite handy.
- The car's LTE could be using multiple providers (e.g. via an MVNO) to get the best available coverage
- The car has virtually unlimited power for the antenna and a much larger antenna than your cell phone, in a much more ideal position, so it should be able to get reception even when your phone cannot.
