Apple Watch SIMM card?
Hello, purchased the Apple Watch Series 4 from T-Mobile as a Christmas gift and they gave me a SIMM card to install in the watch, there is a slot cover on the side of the watch. Do I need to install the SIMM card? If so how do you get the door open, I have tried repeatedly with one of the little tools they have and cannot get it to open. Any help would be appreciated.
