eSIM Vietnam | Unlimited Data & No Roaming Fees | Simify

You can buy a Vietnam eSIM online from Simify in a couple of minutes — choose your plan, pay securely, and your eSIM QR code arrives by email within minutes. Because you buy your eSIM for Vietnam before you fly, you can install it at home on Wi-Fi and simply connect when you land.

As a trusted Vietnam eSIM provider, Simify connects to major Vietnamese mobile networks — Viettel, Vinaphone and MobiFone — and automatically selects the strongest available signal, and you can switch networks manually any time. You get the reliability of the country’s top networks without having to compare a long list of Vietnam eSIM providers yourself.

We offer flexible Vietnam eSIM plans to match your trip: a fixed-data plan for shorter or lighter stays, and an Unlimited plan for heavier users. Every plan is data-only and supports hotspot and tethering — just note that sharing uses data faster, so the Unlimited plan suits heavy hotspot use best. There’s a Vietnam eSIM plan whether you’re visiting for a weekend or a month.

Yes — Simify offers an Unlimited Vietnam eSIM, so you can stay connected for the whole plan period and use your phone freely for maps, social and messaging without watching a data meter. Choose the plan length that suits your trip, from short stays up to 180 days — it’s the easy, stress-free choice for day-to-day travel.

Simify is one of the most cost-effective ways to stay connected in Vietnam. A prepaid Vietnam eSIM avoids the expensive per-day roaming the big carriers charge, with clear upfront pricing and no surprise bills. Plans are priced by trip length and data, and first-time customers can unlock a discount by signing up to the Simify newsletter — so it typically works out far cheaper than telco roaming.

Yes — every Simify Vietnam eSIM is prepaid, so it works on a simple pay-as-you-go basis: pay once up front, with no contract and no postpaid bills. If your trip runs long, you can top up an eligible Unlimited eSIM with extra days in the Simify app, or choose the unlimited option up front. No surprises, no bill shock with our prepaid Vietnam eSIM.

Definitely. Our Vietnam tourist eSIM is built for travellers and short-term visitors — no passport, no local address and no shop queue required. It’s a popular choice among Vietnam eSIM providers for tourists because you can set it up at home before you fly and connect the moment you land.

A Vietnam eSIM is a digital SIM — there’s no physical eSIM card to insert. Your phone downloads the profile from a QR code. If you’d prefer a physical Vietnam SIM card as a backup for an older device we offer that too, but most modern phones only need the digital e-SIM.

No — Simify Vietnam eSIMs are data-only, so they don’t include a local phone number or traditional calls and texts. The eSIM runs alongside your home SIM so you keep your existing number, and you can call and message over data using WhatsApp, iMessage or FaceTime. Keep your home SIM switched on if you still want to receive standard calls or one-time passcodes (SMS).

Yes — Simify is a purpose-built travel eSIM for Vietnam. It gives Aussie travellers fast internet and data the moment they land, with no roaming fees and no SIM swapping. Whether it’s a city break or a month exploring the country, our Vietnam travel eSIM keeps you online.

Yes. Your eSIM has nationwide coverage across Vietnam including Hanoi, Ho Chi Minh City, Da Nang and Hoi An. Signal may briefly vary on remote coastal stretches or out on Ha Long Bay but reconnects quickly — you can check routes and timings on Google Maps or the Baolau app throughout the journey.

Absolutely. Turn data roaming on when you land and you’ll have an immediate 5G/4G connection — open Grab, Be or Xanh SM and book your ride while you’re still walking to arrivals, no airport Wi-Fi queue needed.

Vietnam-only plans cover the whole country. If your trip includes Cambodia, Laos or Thailand, choose our Asia eSIM — data works across Vietnam and neighbouring countries with no profile switching. For a bigger trip, our unlimited Global eSIM keeps you online across dozens of countries.

Installing your eSIM doesn’t start your plan — validity begins when it first connects to a supported network at your destination, so you can buy and install up to 180 days before you travel. Keep the eSIM line switched off until you arrive, then turn it on and enable data roaming to connect. That way your plan won’t start early.

An e-SIM (or “e sim”) is a digital SIM built into your phone — there’s no plastic Vietnam e-SIM card to insert or swap. For Vietnam it simply means you download your plan and connect while your normal SIM stays in place. Every Simify Vietnam e-sim is data-only and runs alongside your existing SIM.

The best-value Vietnam eSIM depends on your trip: shorter or lighter trips suit a fixed-data plan, while longer or heavier trips suit the Unlimited plan. First-time customers can unlock a discount by signing up to the Simify newsletter, and multi-trip or multi-country bundles can save more again — so it works out cheaper than telco roaming either way.

Every Simify Vietnam eSIM is a data-only plan — great for maps, social and staying in touch over WhatsApp, iMessage or FaceTime. Fixed plans come with a set data amount for your trip, while the Unlimited plan gives you high-speed data throughout your plan period. Just pick the Vietnam data eSIM that matches how much you expect to use.

Yes. Alongside our Vietnam-only plan we offer an Asia eSIM covering Vietnam plus Cambodia, Laos, Thailand and other Asian countries, and an unlimited Global eSIM — handy when Vietnam is one stop on a bigger trip. One eSIM covers multiple countries with no reinstalling at the border, and all plans are data-only.

Yes — your Vietnam eSIM provides mobile internet right across the country on major Vietnamese networks, from Hanoi and Ha Long Bay to Hoi An, Da Nang and Ho Chi Minh City. Coverage is near-total in cities and towns; speeds can dip in the northern highlands around Sapa and Ha Giang or the Mekong Delta backwaters, so it’s worth downloading offline maps for those stretches.

For a short city break, a smaller fixed Vietnam eSIM data plan is usually plenty; for longer trips or heavier use, the Unlimited plan won’t stop mid-trip and is better value. Match the plan’s data and validity to your travel dates — and if you’ll hotspot a laptop or tablet, the Unlimited plan handles that best.

Simify is an established travel-eSIM provider used by over 1,000,000 travellers and rated Excellent on Trustpilot. Instead of scrolling a long Vietnam eSIM providers list, you get one trusted provider on major Vietnam networks, with friendly human support and a 100% money-back guarantee if your eSIM doesn’t work and you’ve contacted our team.

After you buy, your QR code arrives by email. Install it on Wi-Fi before you fly (installing won’t start your plan), keep the eSIM turned off until you arrive, then switch it on and turn data roaming on to connect. Setup takes a couple of minutes — no shop visit and no passport needed.
