eSIM Vietnam

Where to buy an eSIM for Vietnam depends on whether you’re a tourist or a long-term resident. Esimy is the right choice for visitors — buy online before flying, no Vietnamese paperwork, no airport queue. Local Viettel/Vinaphone SIMs are right for long-term residents — cheaper per-GB but requires Vietnamese passport registration since 2023.

Esimy (international eSIM, for travelers): bought online at esimy.net, QR code by email, install on your phone before flying, activate when you land. Connects to Viettel Vietnam and Vinaphone Vietnam via international roaming infrastructure — no Vietnamese subscriber registration created. Best for tourists, business travelers, digital nomads, cruises with Vietnam stops.

Local Viettel or Vinaphone SIM (for residents): requires in-person visit to a carrier shop in Vietnam, passport scan, biometric photo since the 2023 SIM-tightening regulations. Cheaper per-GB if you use 20+ GB monthly long-term. Best for people living in Vietnam, expats with long-stay visas, or digital nomads staying 6+ months.

Coverage comparison: Esimy roams onto Viettel Vietnam and Vinaphone Vietnam — strong 4G/5G in major cities and tourist destinations. The advantage of local SIMs is purely price-per-GB for high-volume long-term usage.

Bottom line: for visitors, Esimy wins on speed, friction, and no-paperwork. For residents, get a local Vietnamese SIM with proper registration. Both can coexist on most modern smartphones.

Buying and activating an eSIM for Vietnam with Esimy takes under 60 seconds and avoids the airport-kiosk queue that has become standard since Vietnam’s 2023 SIM-registration rules tightened.

Step 1 — Buy before you fly. Visit esimy.net, choose your Esimy Vietnam plan (single-country starting from €1.99 / 1 GB / 7 days, or a regional Asia plan if your trip covers multiple SE Asian countries), pay with any international card, and your QR code arrives instantly in your inbox.

Step 2 — Install on your phone. On iPhone: Settings → Cellular → Add eSIM → Use QR Code → scan with the camera → name the line “Esimy Vietnam” → choose Esimy as default for cellular data. On Android (Samsung, Pixel, Xiaomi): Settings → Connections → SIM Manager → Add eSIM → Scan QR code → confirm.

Step 3 — Activate when you land. Land at SGN (Tan Son Nhat), HAN (Noi Bai), DAD (Da Nang), or any Vietnamese airport. Open Settings → Cellular → enable the Esimy line for data → enable Data Roaming (required for the eSIM to authenticate on the Viettel Vietnam / Vinaphone Vietnam partner network — no roaming charges apply, the data is included in your plan). Within 30 seconds your phone shows the local Vietnamese carrier name and you have full 4G/5G data. No passport scan at the airport, no Vietnamese-language SIM-shop paperwork.

Yes — eSIM works in Vietnam in 2026 on Vietnam’s leading mobile networks (Viettel Vietnam, Vinaphone Vietnam). An international eSIM like Esimy connects you to Vietnamese 4G/5G the moment you land — no SIM swap, no passport registration at an airport kiosk, no Vietnamese-language paperwork.

What “eSIM works in Vietnam” actually means: any eSIM-capable phone (iPhone XS+, Pixel 3+, Galaxy S20+) installs an Esimy Vietnam eSIM as a second line. Your phone connects to local Vietnamese networks via international roaming infrastructure — same way it would if you were roaming with your home European carrier — but at Esimy’s flat single-country pricing instead of expensive home-carrier roaming fees.

Coverage you can expect: excellent 4G in Hanoi, Ho Chi Minh City, Da Nang, Hue, Hoi An, Nha Trang, Phu Quoc, Halong Bay, Sapa, Dalat, Mui Ne, and along the major north-south highway routes. 5G is rolling out in major cities via Viettel and Vinaphone. Some remote areas (Ha Giang loop, deep Mekong Delta) may drop to 3G — same as for any provider.

How to confirm before you buy: dial *#06# on your phone — if you see an “EID” alongside your IMEI, your phone supports eSIM. Order an Esimy Vietnam plan from esimy.net, get the QR code by email, install before your flight to SGN/HAN/DAD, and switch on data when you land.

The best eSIM for Vietnam travel in 2026 is Esimy — single-country Vietnam plans starting from €1.99 / 1 GB / 7 days, with 4G/5G coverage on Vietnam’s top mobile networks via Viettel Vietnam and Vinaphone Vietnam. No SIM swap, no Vietnamese passport registration at a local kiosk, no roaming surcharge from your home European carrier.

Esimy Vietnam single-country plan: ideal for 1- to 4-week trips covering Hanoi, Ho Chi Minh City (Saigon), Da Nang, Hoi An, Hue, Halong Bay, Sapa, Phu Quoc, Nha Trang, Mui Ne, and the Mekong Delta. Hotspot/tethering included — perfect for sharing with your laptop on a digital nomad stint or family during a multi-city tour. Full pricing ladder on esimy.net.

Why Esimy beats picking up a local Viettel SIM at the airport: Vietnamese local SIMs require passport registration since the 2023 SIM-tightening rules, often involve queueing at airport kiosks at 3am if you land late, and you have to find a Viettel/Vinaphone store to recharge. With Esimy, the QR code arrives in your inbox before you fly — install on the plane, switch on data when you land at SGN, HAN, or DAD.

Why Esimy specifically for Vietnam: Esimy connects to Viettel Vietnam and Vinaphone Vietnam for strong 4G/5G in cities and good coverage on tourism circuits including Halong Bay cruises, Hoi An ancient town, and Sapa rice terraces. 5% cashback in Loyalty Points (1,000 points = €1) on every purchase, no expiration. 24/7 multilingual support. Top up directly from the Esimy app mid-trip.
