- Instant setup — Buy online, scan a QR code, done. No airport queues, no physical SIM cards, no paperwork.
- Keep your home number — Your existing SIM stays in your phone for calls and texts. The eSIM handles data only — no one back home notices you've left.
- Cheaper than carrier roaming — International roaming typically costs $5–$15/day. An eSIM costs a fraction of that — from just $12.50 AUD.
- Works on arrival — Your eSIM connects to the local network automatically when you land in Vietnam. No manual configuration needed.
- iPhone & Android — Compatible with iPhone XS and later, Samsung Galaxy S20+, Google Pixel 3+, and most phones released since 2019.
Mobile Connectivity in Vietnam
Vietnam's mobile networks have improved dramatically in recent years, with fast 4G LTE now covering most of the country. Data is incredibly cheap by global standards, and connectivity in cities is excellent.
Major carriers: Viettel, Mobifone, and Vinaphone.
Coverage quality: Excellent in Hanoi, Ho Chi Minh City, Da Nang, Hoi An, and Nha Trang. Good along the coast and major highways. Coverage weakens in mountainous areas like Sapa and Ha Giang, though main towns still have signal.
Grab for transport and food delivery, Google Maps for navigation, Zalo for messaging with locals, and Vietnam Airlines or VietJet apps for domestic flight management.
Why not just buy a local SIM?
Local SIM stalls cluster around airports and tourist areas but require passport registration. Scams are common with overcharging and fake unlimited plans that throttle heavily. Language barriers make troubleshooting difficult. An eSIM skips this entirely — buy online, scan a QR code, and connect the moment you land.
Travel tips for staying connected
- Grab is the safest and most reliable transport option. Having data means you avoid the hassle of negotiating with taxi drivers who may try to use tampered meters.
- Download offline maps for Ha Giang and Sapa if you're riding motorbikes in the north. Signal drops frequently on mountain passes and you'll need GPS for navigation.
- Vietnam has no significant internet censorship for travellers. Facebook, Instagram, WhatsApp, and YouTube all work fine, though some political content is occasionally restricted.
