My wife and I will be going on a Caribbean cruise soon. Our ports of call are:

San Juan (Puerto Rico)

Oranjestad (Aruba)

Willemstad (Curaçao)

Castries (St. Lucia)

Basseterre (St. Kitts)


My mother-in-law has offered her T-Mobile hotspot. Will we have coverage in those places and what speeds are we likely to get?
