Besides cctbvi has a location on VG, what other company has a store that I can buy a physical SIM card for 7 days? My flight arrives at EIS, then I am taking the ferry to VG. Can I find SIM card in EIS airport?
While we've used mrsimcard on several trips and overall been happy with them, be sure to read the notes about what calls are free and what is charged. Incoming are free but you do get charged for outgoing calls and texts and there are data limits.
Our Verizon plan for $10 a day (only when used) let us get covered by our home plan.
