We use to buy the sim, but switched to WIFI calling
and Whatsapp.

We do have the $10 international plan with AT&T, but can't remember, do we have to take it off Airplane Mode
if we need to use it in a non-WIFI area? I don't think the problem ever came up.

I've dialed local numbers and was automatically charged a very small amount, since they aren't included
in WIFI calling. I'm guessing that if we called out of a WIFI area, to the states, the plan would automatically kick in to the emergency plan.

It's been a while...senior moments, lol---- rereading what Boucharda wrote, I have the answer,
but would like to know if there is a directory
of Whatsapp numbers for local businesses in SXM?
