I want to be able to FaceTime the U.K. from Mexico so I’d like to buy a SIM card and put it in my unlocked U.K. iPhone (there’s no WiFi where we’re going).
Will this work and is there somewhere in Cancun airport I can get one when I arrive? Alternatively, is there somewhere near Riviera Maya I can go to get one? (Preferably one that doesn’t cost a fortune for data).
