These eSIMs cover Vietnam and more countries on one plan.
Will my eSIM have signal in Vietnam?
Your eSIM works on MobiFone, Viettel Mobile and Vinaphone, and your phone picks a network by itself. These networks run 5G, so you'll get it wherever it's on offer. Cities, towns and main tourist areas are well covered; signal can drop in remote mountain areas.
Your data reaches the internet through Hong Kong, a normal setup for travel eSIMs. You can read more about why your IP address shows another place. Daily plans slow to the fair-use speed once you've used that day's allowance.

Using your phone in Vietnam: data tips
- Arriving: Install your eSIM at home on Wi-Fi, so there's little to do on arrival. Land at Noi Bai in Hanoi (HAN), Tan Son Nhat in Ho Chi Minh City (SGN) or Da Nang (DAD), switch it on, and turn on data roaming for the eSIM line.
- Getting around: Pin your pickup, book with Grab, Be or Xanh SM, and watch the car roll up. Your maps keep you on track between stops, and you'll find the same apps in Hanoi, Ho Chi Minh City, Da Nang, Hoi An and Ha Long Bay.
- Staying in touch: Zalo and Messenger are the messaging apps to have ready. Your home number stays on for calls and texts while you travel, so people at home can still reach you.
- Blocked services: Telegram is blocked in Vietnam. Your eSIM can give you a Hong Kong IP address, which may help with some blocked services.
