We used to have Verizon as our cell provider, but have switched to Consumer Cellular.  I'm wondering if anyone has had experience (good or bad) using Consumer Cellular's international coverage while on a southern Caribbean cruise?  I was told that I'll need to switch my sim card-- currently AT & T (...they have a partnership with Consumer Cellular) to T-Mobile (also, a partner).  We will be sailing on RC Freedom of the Seas.
Thank you for any input you might provide.

My advice is for simplicity sake, forget the sim card ideas and simply activate WiFi calling before your cruise and then once onboard put the plane into airplane mode, then enable WiFi and use WiFi calling on any island you visit where WiFi is available.
Here's the info on how to use WiFi calling with Consumer Cellular: https://www.consumercellular.com/blog/asked-answered-using-wi-fi-save-money/
I've tried the "swap out sim card" plan and it's a huge pain in the butt and not worth the effort (or cost).
