10 Best eSIM for Vietnam 2026 (Viettel Tested Plans)

Stepping off the plane at Tan Son Nhat with no data means no Grab ride, no Google Translate, and no idea how to reach your hotel in District 1. Vietnam welcomed a record 2.5 million international visitors in January 2026 alone, up 18.5% from the previous year.

That flood of travellers is landing in a country where street wifi is unreliable and physical SIM counters at airports charge 200,000 VND for plans you can get digitally for half the price. A good eSIM for Vietnam fixes this before your boarding call.

Vietnam's three major carriers now collectively run over 31,000 5G base stations. Viettel leads with 90% outdoor 5G coverage and 12 million 5G subscribers.

I have activated eSIM profiles across all three Vietnamese networks on trips through Hanoi, Da Nang, and Ho Chi Minh City. These are the ten providers that performed best.

The platform offers data only plans with hotspot sharing included on every tier. Activation takes about three minutes through a QR code scan, and you can install the profile days before your flight.

For travellers arriving at Noi Bai or Tan Son Nhat who want guaranteed data the moment they land, Amigo delivers that reliability without fuss.

2. GigSky

GigSky stands apart with a genuine free 100MB trial plan for Vietnam, letting you test network speeds before spending anything.

The paid catalogue includes 12 Vietnam specific plans and 38 multi country bundles covering wider Asia Pacific. Plans scale from 1GB at $7.99 all the way up to 100GB for $161.99 over 180 days.

That 180 day validity is ideal for anyone doing multiple Vietnam trips in a single year. Auto renewal keeps your data flowing if a plan expires mid trip.

3. Saily

Saily offers dedicated Vietnam unlimited plans starting at $34.99 for 10 days with 5GB of high speed data per day before throttling to 1Mbps.

Fixed plans begin at $3.99 for 1GB over 7 days, and the 20GB option costs $28.99 for 30 days. The eSIM profile is reusable across 200 destinations, so the same profile works if you continue to Cambodia or Laos.

Digital nomads working from cafes in District 1 or Da Nang will find the unlimited daily allowance covers video calls and cloud syncing without worry.

4. Airalo

Airalo routes Vietnam data through Viettel and VNPT (Vinaphone), giving you access to the two strongest networks in the country.

The Xin Chao local plan starts at $4.50 for 1GB over 7 days, with the best value sitting at 20GB for $32 over 30 days, which works out to $1.60 per GB. Top up packages let you add data mid trip without buying a new profile.

For backpackers travelling from Hanoi to the Mekong Delta, Viettel routing means consistent signal even in rural stretches between cities.

Why Airalo for eSIM for Vietnam: Viettel network access is the single biggest advantage any provider can offer in Vietnam. Airalo's Xin Chao plans run on Viettel and VNPT, covering both urban and rural Vietnam with consistent 4G LTE. The top up feature adds flexibility that most competitors lack.

5. MobiMatter

MobiMatter aggregates Vietnam eSIM plans from multiple wholesale providers, consistently surfacing some of the lowest per GB pricing available.

The platform lets you compare plans by data amount, validity, and carrier quality before purchasing. For travellers who treat data like a commodity and want the cheapest possible rate for a two week trip through Vietnam, Mobimatter delivers on price.

6. Maya Mobile

Paid plans start at $4.99, and the unlimited option gives 3GB per day of high speed data before dropping to 1Mbps. Every plan includes wifi sharing and comes with a 100% money back guarantee.

The 10 day unlimited plan at $29 suits digital nomads or travellers who stream content heavily during their Vietnam stay.

7. Lotso Travel

8. Instabridge

Instabridge offers 4 dedicated Vietnam plans ranging from 1GB to 20GB, priced between $2.50 and $68.

The 10GB plan for 30 days sits at a sweet spot for two week trips through Vietnam. Where Instabridge adds real value is the 8 multi country bundles that include Vietnam alongside Cambodia, Laos, and Thailand.

Backpackers running the classic Indochina route will find one Instabridge regional plan covers the entire journey without buying separate eSIMs in each country.

9. iRoamly

iRoamly starts Vietnam plans from just $1.20 with unlimited hotspot sharing on every tier. The provider connects through local Vietnamese networks and offers both daily data cap and total data plans.

The unlimited option throttles to 1Mbps after 3GB per day, while a second tier drops to reduced speed after 2GB daily. Groups and couples travelling Vietnam together benefit most because one person can buy a plan and share the hotspot connection across all devices without any data penalty.​

10. Billion Connect

Billion Connect provides prepaid Vietnam eSIM plans through their BC eSIM app with quick activation and flexible short term data bundles.

The platform covers 200+ countries, and their Vietnam plans suit business travellers on 3 to 5 day trips who need reliable data without committing to a 30 day plan. The app lets you keep your home number active for calls and texts while using the eSIM for data.
