Almost forgot- White Bay JVD there is a very good chance your phone will be getting a good signal from your US carrier coming off a cell tower at STT. I had a 4 bar signal with LTE data from ATT for the two days we were in White Bay. You won't get this in Great Harbor or Little Harbor, but White Bay is a good bet.
I have some friends with a mooring at sopers hole. They received a bill for approximately $6,000 accumulated over a few months. They told their US carrier that we were on a US tower. The carrier told them, you were in the bvi. We’re obligated to charge and share per our agreement......
Im told that we will have a wireless receiver on our catamaran that we are bareboating from BVIYC. We will apparently have our own hot spot so I am assuming that if we are within reach of a tower we will have WIFI available unless this is a satellite connection. Some of our crew need a connection for work related stuff occasionally. I would expect that wherever the local internet users are able to get it, we should too.
On a sailboat that I was on from BVIYC last year it was equipped with a cellular data hot spot that those onboard connected to via wifi. There was a daily charge for the data. Since there were only two of us on board I just used my cell company roaming services. The islands are well covered by cell service. I would think the free wifi signals from shore would be very limited
