Indian international roaming packs are expensive and often have tiny daily data limits. A local airport SIM means standing in a queue, showing your passport and losing your Indian number while it's swapped out. An eSIM solves all of this — it's a digital SIM that downloads straight onto your phone. If you're new to the technology, here's a quick primer on what an eSIM is and how it works.
- Instant activation — set it up at home before your flight; no kiosks in Vietnam.
- Far cheaper than Indian roaming for the same amount of data.
- Keep your Indian number active — your physical SIM stays in for calls and OTPs while the eSIM handles data.
- No physical SIM to lose or fiddle with at the airport.
- No bill shock — you pay a fixed price upfront. (More on how to avoid roaming charges abroad.)

Mobile Networks & Coverage in Vietnam
Vietnam has three major mobile networks: Viettel (the widest coverage, including rural and mountain areas like Sapa), Vinaphone and Mobifone. Our Vietnam eSIM connects to these top networks automatically, so you get strong 4G/5G in cities like Hanoi, Ho Chi Minh City, Da Nang, Hoi An and Nha Trang, plus solid coverage in tourist spots such as Ha Long Bay and Phu Quoc.
How to Set Up Your Instant eSIM for Vietnam (Step by Step)
- Buy your Vietnam eSIM plan on our website and complete payment.
- You'll instantly receive a QR code by email (and in your account).
- On your phone, open Settings → Mobile/Cellular → Add eSIM and scan the QR code.
- Label the eSIM (e.g. "Vietnam") so it's easy to find.
- Set the Vietnam eSIM as your data line and turn on data roaming for that line only (this is normal and required for travel eSIMs — it won't charge your Indian number).
- Land in Vietnam, and your data connects automatically.
Tip: Install the eSIM at home on Wi-Fi before you fly — but don't worry, your plan's validity usually starts when you first connect in Vietnam. See our full eSIM setup guide for international travel.
