A:Answer Not necessarily! Be careful! I bought an open-box Series 4 Apple Watch, silver stainless, "GPS+Cellular" model that was NOT supported by Verizon. Once I rec'd the watch, I contacted Verizon with the actual IMEI number only to find out it was not compatible. I had to return it today, and there are no more Verizon versions in stock. It was certainly a gorgeous watch. Sigh.
