Apple Watch on a different carrier than the iPhone
My carrier (Mint Mobile) do not support Apple Watch. Getting a Watch LTE tied up to the same phone number, I would need to switch carriers for the whole family. That would be both expensive and a huge hassle.
Can I have the watch on a different carrier? T-mobile offers $5 / month watch only plan. If I would sign up with that, what are the downsides compared to having the watch on the same operator?
