Best eSIM for Vietnam
Best eSIM for VietnamOur verdict: For most trips to Vietnam, a mid-size data plan on Simzora is the best balance of price and coverage. You get Viettel and Vinaphone reach across Hanoi, Ho Chi Minh City and Da Nang at an honest per-GB price, delivered to your phone in minutes.
How much data do you need for Vietnam?
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.
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.
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.

Best eSIM for Vietnam, FAQs
Which eSIM is best for Vietnam?＋−
For most travellers, Simzora is a strong pick: it roams on Viettel and Vinaphone 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, mostly on Viettel, which reaches furthest of the Vietnamese networks. 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.
