Unlimited Data eSIM Vietnam — 30 Days (1 Month)
Daily Limit - 3 GB at Full Speed
Your plan is unlimited, but you get 3 GB per day at full 4G/5G speed. Once the 3 GB is used, your connection doesn't cut out - speed simply drops to 1 Mbps (still plenty for messaging apps, social media and navigation). The 3 GB quota resets automatically the next day.

Why Travelers Choose an eSIM for Vietnam
Heading to Hanoi, Ho Chi Minh City or a Ha Long Bay cruise? A Vietnam eSIM connects to Viettel, Vinaphone or MobiFone the moment you land at Noi Bai (HAN), Tan Son Nhat (SGN) or Da Nang (DAD) — no Viettel Store queue, no passport check at a mobile kiosk. Activate a plan in two minutes, scan the QR code, and you're online for Grab motorbike rides through Old Quarter Hanoi, booking Ha Long Bay overnight cruises, or uploading Golden Bridge photos from the Ba Na Hills cable car. Choose a 7-day 3 GB plan for a Hanoi + Ha Long weekend, a 30-day 10 GB plan for a full North-to-South Vietnam tour through Hue, Hoi An and the Mekong Delta, or Vietnam eSIM unlimited data if you're settling into a Da Nang coworking scene.
eSIM vs Vietnamese Tourist SIM — Which Works Best on Arrival?
Vietnamese carriers (Viettel, Vinaphone, MobiFone) sell tourist SIMs at Noi Bai and Tan Son Nhat airports, but a Vietnam eSIM activates before you land and skips the passport registration the physical Vietnamese SIMs require.
| eSIM | Viettel Tourist SIM | |
|---|---|---|
| Setup time | ≈ 2 minutes (QR scan) | 15–30 minutes (counter + passport) |
| Cost | from ~$0.50/day | 200,000–500,000 VND (~$8–20) tourist pack |
| Passport register | none | required at all Vietnamese carrier counters |
| Coverage | Viettel / Vinaphone 4G/5G | same carriers |
| Top-up | instant online | Viettel store or app |

Which is the best eSIM for Vietnam?
The best eSIM for Vietnam depends on your trip — a 7-day 3 GB plan covers a Hanoi + Ha Long Bay weekend, a 30-day 10 GB plan fits a full Vietnam North-to-South tour through Hue, Hoi An and the Mekong Delta, and Vietnam eSIM unlimited data suits digital nomads in Da Nang or Ho Chi Minh City. Our Vietnam eSIMs run on Viettel and Vinaphone, Vietnam's biggest networks, so 4G/5G coverage is strong in cities and reliable on the main train lines.
Does Vietnam support eSIM and how do I activate?
Yes — Vietnam fully supports eSIM, and all three Vietnamese carriers (Viettel, Vinaphone, MobiFone) operate eSIM-compatible networks. To activate our Vietnam eSIM, buy online, scan the QR code on your phone (iPhone: Settings → Cellular → Add eSIM; Android: varies by maker), and the profile is installed. Turn on data roaming for the new profile and you're online — no store visit, no passport check needed.
Can I use a Vietnam eSIM for a full month including Ha Long Bay and the Mekong?
Yes — our Vietnam eSIM 30-day plans cover full-month stays from Hanoi to the Mekong Delta with options from 5 GB up to unlimited data. Ideal for travelers doing the classic Vietnam circuit (Hanoi → Ha Long → Hue → Hoi An → HCMC → Mekong) or digital nomads settling in Da Nang or Ho Chi Minh City's District 1. The eSIM stays active as long as your plan is valid.
