With Maya eSIM, travelers can access unlimited data in more than 165 countries (and across 20 cruise lines) with one easy download and no SIM card swapping. How a Maya eSIM works is beyond simple. You purchase a plan through the Maya app or website, follow the two-minute installation steps, and when you land, turn on the Maya eSIM for an immediate connection. From Paris, you take the train to Amsterdam, crossing through Belgium, and your unlimited service continues uninterrupted. Starting at $49.99 for three days, Maya eSIM covers both onboard and at-port destinations, providing connectivity beyond the ship's Wi-Fi network.
