A:AnswerThis Apple Watch model has the capability of setting up optional cellular service. Please check your carrier for compatibility and plan availability.
A:AnswerMy wife and daughter just bought the 40mm ones and they both came with a large/longer and small/shorter band with each one! It’s a good thing to as both of them have very small wrists!!!!
A:AnswerNo separate band purchase is required. The watch comes with a S/M band, and also a L/XL band. I initially wore the S/M but it was too tight, so I switched to the L/XL. I’m glad you know your husband’s band size in advance.
A:AnswerCellular requires you to pay for a monthly data subscription via your cellular carrier. It allows you to connect to your watch using Bluetooth and listen to Apple Music, otherwise with GPS, you need to have your phone nearby to do so. You can answer and make calls with the cellular watch without your phone needing to be nearby. Granted, this would not allow FaceTime, as the watches do not yet have a camera, but even when a FaceTime call is received you can still answer on your watch as a voice speaker call.
