Using Apple Watch 5 on Consumer Cellular's AT&T network sim card?
I've read other answers that say Consumer Cellular is not on the list of approve carriers but I don't know why it wouldn't work since Consumer Cellular uses AT&T's network.
My iPhone 11 uses AT&T's network through Consumer Cellular.
I want to take advantage of AT&T's current $18 a month payment offer for the GPS+Cellular Apple Watch 5 and want all the features supported.
A T-Mobile network sim card is available too and which one you get usually depends on who has the better coverage in your area. I requested the AT&T sim card and so got that.
