Cash, payments and connectivity on Lý Sơn

Ask your accommodation, driver and activity provider whether they accept cash, card or a transfer you can actually make. A domestic banking QR code may not work with your foreign banking app. Agree on the total, deposit and balance before paying, and request a record. Carry enough accessible cash for essential purchases without putting the entire trip budget in one wallet.

Check withdrawal options with your own bank and locally for your route, including fees and card compatibility. Do not wait until a boat departure to discover a payment problem. Divide cards and cash sensibly between secure places and keep a small usable amount separate. There is no basis here for claiming that the island has no ATMs or that every merchant rejects cards.

Download tickets, accommodation confirmation, a map of your chosen areas and the port meeting point. Save the host's and carrier's numbers in a format you can dial, not solely inside an app conversation. Carry a charged power bank according to your carrier's transport rules. Keep identification available in the form required for boarding; a photograph is not automatically an accepted replacement.

International visitors should confirm roaming charges, data allowance and whether their SIM or eSIM provides ordinary calls as well as data. If remote work matters, ask the host about the connection at the actual room and a backup arrangement rather than relying on a generic Wi-Fi icon. Download larger files in advance and avoid making an important meeting depend on an unverified connection.
