Pairing an iPhone and Apple watch that have different wireless carriers
I currently have an iPhone and Apple Watch paired and on a cellular plan with the same wireless carrier. Getting ready to switch to a carrier that doesn't support Apple Watch. I will leave the watch with the old wireless carrier and cellular plan, but move the iPhone to the new wireless carrier and cellular plan. Will everything still function seamlessly? Does the iPhone and Apple Watch need to be with the same wireless carrier to function on a cellular network?
