Can my son use Apple Watch SE without a cellular plan?
Can my son continue to use his Apple Watch SE without a Celular Plan? We set up his watch with his own Apple ID and phone number, managed by my iPhone, while we were on Verizon. We recently switched to Mint Mobile, knowing that they don't support Apple Watches, but hoping he would still be able to use WiFi for iMessage with friends (or us) who also had Apple IDs. That doesn't seem to be the case -- if he texts me it's as a green SMS and it (of course) doesn't go through).
Anyone have any sunshine to shed on this? We'll be switching back to Verizon next year, but in the meantime shouldn't he be able to use his Apple ID, which I thought wasn't tethered to a specific cell phone?
