Every eSIM can be installed within 180 days of purchase. Plan validity starts when you first connect.
Your eSIM picks between these networks on its own. If you see bars and nothing loads, you can pick one by hand.
Your Bahamas eSIM runs on one network: BTC. 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 BTC by hand.
Bahamas has two main carriers: BTC (Bahamas Telecommunications Company, historic state operator with largest nationwide coverage) and Aliv (recent market entry, strong in Nassau and Grand Bahama). Plugs are Type A and B (American format, 120V — same as the US, no adapter needed). 4G coverage reaches Nassau, Paradise Island, Grand Bahama (Freeport), Bimini, and Eleuthera. On less-populated islands (Exuma, Andros, Inagua) coverage follows inhabited areas.
Nassau's Lynden Pindling Airport (NAS) offers free WiFi limited to 30 min. The currency is the Bahamian dollar (BSD, pegged 1:1 to USD); USD is accepted everywhere with no penalty. Use Royal Bank of Canada Bahamas, Scotiabank, or Commonwealth Bank ATMs. Tips are 15-18% (sometimes already included as "gratuity"). Driving on the left — British legacy. Beware cruise ports in Nassau: dock taxis have fixed fares (verify first). Paradise Island beaches are Atlantis private but neighboring resorts have public access.
