How to Get eSIM in Vietnam: A Guide to Mobile Data

You can get an eSIM for Vietnam online in less than ten minutes before your flight departs. Buying an eSIM online from international providers like Airalo or Nomad is the fastest way to secure mobile data. These digital cards activate immediately upon arrival when your phone connects to a local network. Prices start from $5 (approximate) for basic data packages lasting seven days. However, these international eSIMs usually only provide data, not a local phone number. If you need to make voice calls to local businesses or taxi drivers, you will need a local SIM card instead. Ensure your smartphone is carrier-unlocked before purchasing any digital card.

The choice between a physical SIM and an eSIM depends on your phone's compatibility and your need for a phone number. eSIMs offer convenience because you do not have to swap physical plastic cards. This keeps your home SIM active for receiving emergency security codes from your bank. On the other hand, physical SIM cards sold at airports include a local phone number. This number is useful for registering on local ride-hailing apps like Grab. Buy physical SIM cards at airports like Nội Bài in Hà Nội or Tân Sơn Nhất in Hồ Chí Minh City. Prices for physical tourist SIMs start from $10 (approximate) and include generous data limits.

Viettel and Vinaphone offer the widest and most reliable network coverage across Vietnam. Viettel is the largest state-owned telecom provider. It offers strong signals in remote regions like Sa Pa or Hà Giang. Vinaphone also provides excellent high-speed coverage in major cities like Đà Nẵng, Hội An, and Nha Trang. Mobifone is another major provider, though its signal can be weaker in deep rural areas. If you plan to travel off the beaten path, choose an eSIM or SIM card that utilizes the Viettel network.
