Vietnam eSIM | Travel Data Plan with Instant Activation

Why use an eSIM in Vietnam?

1
Vietnam is heavily app-mediated for tourists — Grab for taxis, Booking.com for last-minute hotels, Google Translate for menus.
2
ATM-style SIM vending machines at Noi Bai and Tan Son Nhat airports are inconsistent and often out of stock.
3
Crossing in from Cambodia or Laos overland? eSIM works the moment you touch Vietnamese cell coverage.

4G LTE nationwide with very strong urban coverage. 5G is rolling out in Ho Chi Minh City and Hanoi.

Cities & areas covered

✓
Ho Chi Minh City
5G is live in District 1 and District 3. Use Grab for everything — local taxis are notorious for meter scams.
✓
Hoi An lanterns
Full LTE in the ancient town and An Bang beach. The Cham Islands ferry has signal for the first 20 minutes only.

Will Grab and ride hailing work?

Yes. Grab is the standard for taxis, motorbikes, and food delivery throughout Vietnam — it uses normal mobile data.

Can I use it on Halong Bay overnight cruises?

Mostly yes — main routes have LTE. Expect occasional dropouts deep among the islands.

Does the eSIM work overland from Cambodia?

Yes. The eSIM activates automatically when your phone connects to a Vietnamese cell tower.

Is data fast enough for video calls?

Yes, in cities. Viettel's 4G in Hanoi and HCMC is reliable for FaceTime and WhatsApp video.

What if I'm doing a multi-country Southeast Asia trip?

Buy a regional Asia plan in the Beaver eSIM app instead of multiple country plans — one eSIM covers Vietnam, Thailand, Cambodia, Laos.
