Why would I need an eSIMFlyer plan for the USVI if my AT&T, T-Mobile, or Verizon service typically covers U.S. territories?

Even with major US carriers, flying into the USVI can lead to unexpected roaming fees due to "accidental international roaming." The islands are geographically close to the British Virgin Islands (BVI), and your device might inadvertently connect to a BVI cell tower, especially around areas like St. John. An eSIMFlyer plan ensures you're locked into local USVI networks, avoiding those nasty surprise charges that can hit your bill after you've landed back home. It's about smart travel, not costly surprises.
