eSIM for Hoi An
Hoi An's lantern-lit Ancient Town and the nearby beaches are among the most charming destinations in Vietnam, and they are well covered on every network. Signal is dense in the old town and along An Bang beach, with Viettel the steadiest if you cycle out to the rice paddies or ride the rural road between Hoi An and Da Nang.
An eSIM Vietnam gives you access to the same plans in Hoi An as in the rest of the country. 5 GB is generally enough for maps, messaging and social media, while video streaming and hotspot use require more data. The plans shown range from 1 to 20 GB and start at $1.90. They are fully refundable within 30 days provided the eSIM has not been used on a network at the destination. The activation link is sent by email after purchase.
Getting connected in Hoi An
Hoi An has no airport of its own; most visitors arrive from Da Nang, about 45 minutes north, often by private transfer or Grab. The road in is covered, and the town itself is well connected, so with an eSIM active you arrive ready to navigate to your hotel and book a bicycle. Since much of Hoi An's charm is cycling the surrounding rice paddies and back roads, download offline maps so navigation works even where signal thins.

Coverage in Hoi An
Hoi An has good coverage. The Ancient Town with its lanterns and tailors, the riverside, and the An Bang and Cua Dai beaches all hold strong 4G on every network, with 5G expanding. The famous lantern-lit old town gets congested in the evening when crowds peak, but signal generally holds. Coverage thins slightly on the cycling routes through the rice paddies, the back roads to the Tra Que herb village and the rural lanes toward My Son, and Viettel is the most reliable there. The coastal and rural road to Da Nang is well covered on Viettel.

Where to stay and connect in Hoi An
Ancient Town
The UNESCO old town of lanterns, tailors and riverside cafes. Dense coverage, with only brief evening congestion when the night crowds peak. Walkable and well connected.
An Bang beach
The main beach a short ride from the old town, with beach clubs and guesthouses, well covered. A relaxed base combining beach and connectivity.
Cam Thanh / rice paddies
The green countryside of coconut palms and paddies, with eco-stays and the basket-boat tours. Coverage thins here; Viettel is the steadier network.
Cua Dai
A quieter beach south of An Bang with resorts. Reliable on Viettel, thinning on other networks toward the quieter stretches.
Staying online while you move
Hoi An is best explored by bicycle or scooter, and the old town and beaches stay well covered. The change comes on the rural rides that define the area: cycling the rice paddies to Tra Que herb village, the basket-boat tours in the water-coconut groves, and the lanes toward the My Son Cham ruins all thin out, with Viettel holding best. The coastal road to Da Nang is well covered on Viettel. For a day of cycling the countryside, an eSIM on Viettel plus offline maps keeps navigation working where the signal fades.
How much data in Hoi An
A few days in Hoi An run on 5 to 7 GB, most of it in the well-covered old town and beaches. If you rent a bicycle or scooter for the rice paddies, Tra Que and My Son, a Viettel-based eSIM and offline maps cover the weaker rural stretches. Use the strong town coverage for uploads, and budget a little more if you tether, since Hoi An has a relaxed remote-work scene.
