Vietnam rewards travelers who stay connected. You will want Grab to cross Hanoi or Ho Chi Minh City at a fair price, Google Maps to find that bánh mì stall down an alley, and a translator for menus and markets. Mobile data in Vietnam is fast and cheap, so there is no reason to go without it.
This guide covers how to choose the best eSIM for Vietnam, the egoViet plans that fit different trips, when a Southeast Asia eSIM makes more sense, and local tips from the team that is based right here in Hanoi.

Why Get an eSIM for Vietnam?
- Skip the airport SIM counter. Arrivals halls at Noi Bai and Tan Son Nhat often have queues, and tourist SIM cards need passport registration.
- Book a ride straight away. With data from the moment you land, you can order a Grab instead of haggling with taxi touts.
- Keep your own number for bank codes and messages from home.
- Pay a fraction of roaming prices. Vietnam has some of the cheapest mobile data in Asia, and a local eSIM passes that on to you.
How to Choose a Vietnam eSIM
Trip length
Many visitors spend two to four weeks in Vietnam, traveling north to south. Pick a plan that covers your whole stay plus a spare day. egoViet plans can't be topped up, and if your high-speed data runs out, you stay online at around 128 kbps.
Your route
Vietnam-only trips are best served by a Vietnam eSIM. Adding Cambodia, Laos, or Thailand? See the regional options below.
Your data habits
Maps and Grab use little data. Video calls home, Instagram stories from Ha Long Bay, and working from cafés in Da Nang use a lot more. Here is a guide to how much data you need.

How to Set Up Your Vietnam eSIM
- Check your phone is eSIM-compatible and carrier-unlocked. See our eSIM compatibility list.
- Buy your plan. The QR code arrives by email within minutes.
- Install it at home on Wi-Fi with our installation guide.
- When you land, switch the eSIM on, set it for mobile data, and turn on data roaming for that line. Keep data roaming off on your home SIM.
Tips for Staying Connected in Vietnam
- Get the local apps. Grab is the go-to app for rides and food delivery in Vietnam's cities, and Zalo is how many hotels, homestays, and tour operators chat with guests.
- Download offline maps for the mountains. Coverage is good in towns, but it can drop on remote stretches of the Ha Giang loop or deep in Phong Nha's caves.
- Expect weaker signal on some boat trips. Ha Long Bay and Lan Ha Bay cruises usually have coverage near the shore, but not everywhere between the islands.
- Plan around Tết. During Lunar New Year (late January or February), networks and transport get busy. Book rides and trains early.
- Need to call? egoViet eSIMs are data-only, so use Zalo, WhatsApp, or FaceTime. Here is how calling works with a data-only eSIM.
FAQs: eSIMs for Vietnam
What is the best eSIM for Vietnam?
For a Vietnam-only trip, a Vietnam eSIM on a major local network is the best value. egoViet's Vietnam eSIM uses the Vinaphone and Viettel networks and comes with fixed, daily, and unlimited plans.
Do I need to register my passport for a Vietnam eSIM?
Not for egoViet's Vietnam eSIM. Physical tourist SIM cards bought in Vietnam do require passport registration.
Does the Vietnam eSIM include a local phone number?
No, it is data-only. Use Zalo, WhatsApp, or FaceTime for calls and messages, and keep your home SIM active for SMS codes.
Does mobile data work across all of Vietnam?
Coverage is strong in cities, beach towns, and along the main north-south routes. It can be weaker in remote mountain areas, caves, and some offshore spots, so download offline maps before you go.
