Your eSIM picks between these networks on its own. If you see bars and nothing loads, you can pick one by hand.
Your Anguilla eSIM runs on one network: FLOW. Other local networks won't carry your data: if you see signal bars and nothing loads, turn off automatic network selection (iPhone: Settings → Cellular → your eSIM → Network Selection; Android: Settings → Network & internet → SIMs → your eSIM) and pick FLOW by hand.
Anguilla has two carriers: Digicel Anguilla and Flow Anguilla (Liberty Latin America). 4G covers the entire island (90 km², very small) including The Valley (capital), Sandy Ground, Shoal Bay, and Meads Bay. Plugs are Type A and B (American format, voltage 110V — atypical for British territory, legacy of USVI proximity). Coverage extends several kilometers offshore, useful for snorkeling and short excursions.
Clayton J. Lloyd Airport (AXA) receives connecting flights via Sint Maarten (SXM, 15-min ferry) or Saint Kitts. The currency is the Eastern Caribbean dollar (XCD, pegged at 2.7 XCD/USD); USD accepted everywhere. National Bank of Anguilla and Scotiabank ATMs accept foreign cards. Tips are 10-15%. Anguilla is a British Overseas Territory but uses American plugs and drives on the left — confusing at first. Beaches are among the Caribbean's finest (Shoal Bay East regularly in world top 5) and tend to be empty.
