For the 4 week of back to back cruising I have booked starting on August 9th I upgraded my cellular plan to one that gives me 2G per day high speed in Canada and Mexico, plus free calling in and to Mexico, the US and Canada all the time. . The remainder of my term includes 6 days of global pass that I can activate in Honduras. It was only $40 for the rest of my annual plan which expires December 29th. I use Visible which is subsidiary of Verizon and pay annually. I sail from Galveston on the MSC Seascape with port days in Cozumel, Cost Maya Mexico and Roatan Honduras. I won't have Wi-Fi on Sea days but that OK with me. 4 days a week, Including the day in Galveston each week should be ample coverage for a month. I considered adding GigSky but it would require a new phone as mine is not E-sim compatible. I used this phone and global pass (international roaming) in Mexico last November. As long as it works I'll put off buying another phone till I actually need it.
