Hi Sue -- I have posted a video overview of my trip to the BVIs in Mid-December. SAILING CHARTER - BVI REOPENING VIDEO DEC 2020

I worked the whole trip. I got a simple Google Fi Sim for $80/month which gave me 23GB of 4G/5G data for my video conference meetings and VPN. I disabled the card when I got home. Also my boat and the other charter vessels at TMM have WiFi onboard which gives 30GB for basic browsing, phone and e-mail (Though in a pinch you can stream on it speed is actually very good). It worked everywhere including Anegada.

Hope this helps!
