Wander Hoi An's lantern-lit Ancient Town, the Japanese Bridge and An Bang Beach, always connected.
Hoi An eSIM plans: unlimited, or by the GB.
Every Hoi An eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Hoi An — you can always top up or switch on your next trip.
Unlimited plansHigh-speed data, nothing to count
Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.
- Best for streaming, video calls & hotspot
- Great for longer or open-ended trips
- One price per day — no GB anxiety
A set bundle, brilliant value
A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.
- Best value for lighter, shorter trips
- Clear allowance — pay only for what you need
- Top up any time from your phone
How much data do you need in Hoi An?
A rough, honest guide to sizing your Hoi An eSIM so you're not guessing. Most travellers in Hoi An are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Google Maps, WhatsApp, email and the odd search. Plenty for a city break where you mostly need directions.
Everything above plus social scrolling, music, cloud photo backups and a little video. Where most travellers land.
Netflix by the pool, long video calls home and hotspot for the laptop — go Unlimited and stop counting.
Hoi An eSIM: your local data guide.
Hoi An is made for wandering, from the lantern-strung Ancient Town and the Japanese Covered Bridge to basket-boat rides in the Cam Thanh coconut groves and cycling out to An Bang Beach. A Hoi An eSIM keeps maps, Grab and translation live as you hunt tailors, book a cooking class or find your way back along the unlit rice-paddy lanes after dark.
Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.
Where you'll lean on data in Hoi An.
Look up tailor and workshop reviews, and check the monthly full-moon lantern festival dates before you go.
Pull up the history and photo spots around the 400-year-old bridge, then share pictures across the Thu Bon River.
Order a Grab or map your cycle route out to the beach bars, and check the surf before you set off.
Book a basket-boat tour and use maps to find the launch points among the water-coconut palms.
Getting around Hoi An on your eSIM.
- Grab— Works in Hoi An but with fewer drivers than Da Nang; best for cars to the beach.
- Xanh SM— VinFast's electric taxis and bikes, a growing option for rides around town.
- Mai Linh— Long-established Vietnamese metered-taxi firm; bookable by app when Grab is scarce.
- Google Maps— Essential for cycling routes to An Bang Beach and the Cam Thanh groves; save maps offline.
Most visitors spend two to three days in Hoi An, enough for the Ancient Town, a tailor fitting, a cooking class and a day at An Bang Beach.
A relaxed Hoi An visit is light on data, so 1-3 GB usually covers maps, reviews, translation and lantern-town photos; step up to 5 GB or Unlimited if you plan to stream or work from a beach cafe.
The Ancient Town and central Hoi An have reliable 4G on Viettel, VinaPhone and MobiFone, with 5G growing; coverage realistically thins along the unlit rice-paddy lanes, the coconut groves at Cam Thanh and stretches of An Bang Beach.

Your Hoi An eSIM: data-only, zero bill shock.
Your Hoi An eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Hoi An, no swapping your real SIM out.
The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.
Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.
Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
