📱 Physical SIM vs eSIM in Antigua and Barbuda: Which Should You Choose?
When traveling to Antigua and Barbuda, you have two main options: a physical prepaid SIM card from local providers like Digicel or Flow, or an eSIM from international providers like Holafly. Physical SIM cards are widely available at the airport, stores, and Digicel/Flow shops. They require inserting a nano-SIM into your phone and typically come with local phone numbers and generous data bundles. However, you may need to show your passport to register, and you'll have to swap out your home SIM. eSIMs, on the other hand, are digital SIMs that you install before or after arrival via a QR code. They work with eSIM-compatible phones (iPhone XR and newer, Google Pixel, Samsung Galaxy S20+, etc.) and allow you to keep your home SIM active for calls/texts. eSIMs are more convenient, often cheaper for short trips, and can be purchased online instantly. For Antigua and Barbuda, Holafly offers unlimited data eSIM plans starting at $19 USD for 7 days. If you value convenience and quick setup, an eSIM is the better choice; if you need a local number or have a non-eSIM phone, go with a physical SIM.
