3 GB
Light: maps and messaging
Around 3 GB covers about a week of Grab rides, Google Maps, WhatsApp and the odd photo. If you lean on hotel and cafe Wi-Fi and just need data on the move, this is plenty.

How much data do you need for Vietnam?
Pick the band that matches your trip. Top-up is available on most plans if you run low.
5 to 10 GB
Typical: social, browsing, some photos
Most travellers are comfortable on roughly 5 to 10 GB for a one to two week trip. That handles daily social, translation apps, booking and sharing photos from Hoi An or Ha Long Bay without watching the meter.
20 GB
Heavy: video, hotspot, remote work
For streaming, tethering a laptop or working as you travel, choose 20 GB or an unlimited plan with a daily full-speed allowance. Standard plans top up on the same eSIM if you run low, so you are not left stranded mid-trip.

Why Simzora for Vietnam
No hype, just how the service actually behaves once you land.
Roams on local partner networks
Your eSIM hands between Vietnam's two widest networks to hold the strongest signal, so you stay connected across the cities and along the main tourist corridor from Da Nang out to Ha Long Bay.
Honest per-GB pricing
Every plan is a plain amount of data at a visible per-GB price. No fake unlimited and no surprise charges, just the data you paid for.
Instant delivery, data-only
The QR arrives by email in minutes and installs over home Wi-Fi before you fly. It is data-only, so keep your own SIM in the phone for bank OTP codes while WhatsApp runs over the data.
Best eSIM for Vietnam, FAQs
Straight answers to the questions travellers ask most.
Which eSIM is best for Vietnam?
For most travellers, Simzora is a strong pick: it roams on local partner networks for wide coverage, prices data honestly by the GB, and delivers instantly. Choose the data size that matches your trip rather than paying for a headline unlimited plan you will not use.
How much data do I need for Vietnam?
Light users on maps and messaging get by on about 3 GB a week. Typical travellers doing social, browsing and photos are comfortable on 5 to 10 GB, and heavy users who stream or tether should look at 20 GB or an unlimited plan with a daily full-speed allowance.
Will an eSIM work in places like Sapa or the Mekong Delta?
In the towns and along the main roads it works well on the local partner networks that reach furthest across Vietnam. On the mountain trails around Sapa and in the narrow Delta backwaters the signal weakens, so expect patchy data or the odd dead spot away from built-up areas.
