What matters most
Pick Travel eSIM
Solo or two, 5 days: a travel eSIM is close to the right answer. Install it at home, it connects as you land, and it is usually the cheapest per GB.

Mobile networks in Vietnam
ViettelVinaphoneMobiFone
Vietnam has three main networks — Viettel, Vinaphone and MobiFone. Viettel, run with military-grade ambition, is the largest and has the strongest rural footprint; the other two are solid in cities and towns. Which network a travel eSIM uses matters more here than in most countries, precisely because of that rural gap.
Hanoi, Ho Chi Minh City, Da Nang and every provincial city are well covered with fast data. The differences show up in the mountains and the countryside: the Ha Giang loop, Sapa's valleys and remote stretches of the central highlands are where Viettel keeps a bar or two while others fade. On the classic north–south route the populated corridor is fine on any network.

Doing the Ha Giang loop, Sapa treks or other mountain riding? Prefer a plan on Viettel's network and still expect dead zones on the passes — download offline maps.
Will an eSIM work on my phone?
Two things must both be true: the phone supports eSIM, and it is not locked to a carrier. A locked phone can install an eSIM and still never connect.
Most iPhones from the XS and XR on support eSIM; of those sold in mainland China, only a few recent models do, and inside mainland China an eSIM from abroad cannot be installed. Lock status: Settings → General → About → Carrier Lock should read “No SIM restrictions”.
Menu names differ by maker, and the same model can lack eSIM depending on the country it was sold in. No menu? Use the EID check above.
Answer the two questionsAn EID plus an unlocked phone means a travel eSIM will work.

What to look for in a Vietnam plan
- Days first, data second — a plan that expires mid-trip is worse than one that runs a little low.
- Hotspot/tethering allowed, if you travel with a laptop or share with a partner.
- Which local network it uses — see above; coverage beats a small price difference.
- A top-up option, so you can extend without installing a new eSIM.
- Data-only is normal: most travel eSIMs come without a phone number, and calls happen over WhatsApp or FaceTime anyway.
Good to know in Vietnam
- Grab (rides) and a translation app are near-essential in Vietnam, and both are useless without data — get connected before you need your first ride from the airport.
- Buying a physical SIM locally means passport registration at the counter; an eSIM bought before the trip skips the paperwork entirely.
- Hotel and café WiFi is everywhere and genuinely fast in cities — your data plan mostly needs to cover the hours in between, so mid-sized plans go further than you might expect.

Frequently asked questions
Will WhatsApp and my phone number still work?
Yes. Keep your home SIM installed and WhatsApp stays tied to your usual number while data flows through the travel eSIM.
Can I share the data with my laptop?
Usually yes, via your phone's hotspot — but some plans block tethering, so check the plan details before buying.
When should I buy and install it?
A few days before departure, on home WiFi. Enable it when you land — unless the plan starts at install, which is why you check the activation rule first.
My phone doesn't support eSIM — now what?
A physical tourist SIM on arrival or a pocket WiFi rental still works fine — the comparison above applies the same way.
Why are there no prices on this page?
Because they change weekly. A price table would mislead you within a month, so we link to live pricing instead.
