Common Questions

The details worth knowing about your Vietnam eSIM

The eSIM connects to Viettel, Vinaphone, Mobifone, and Vietnamobile. The first three offer 4G and 5G; Vietnamobile lacks 5G and has no 3G, so it may be slower in fringe areas. In rural and mountainous northern or central highland areas, 4G may be intermittent or unavailable on any network.

Vietnam's 5G uses band n78. If your phone lacks n78, you will get 4G at most. On 4G, bands B1, B3, and B8 are used. Most modern phones support these, but check your device specs before departure if you rely on 5G.

No, this eSIM is for Vietnam only. Coverage stops at the border. If you cross into Cambodia or Laos, you will lose service. You would need a separate eSIM or a regional plan for those countries.

No, local regulations do not throttle or filter eSIM data for foreign visitors. You get full, unfiltered internet access at the median download speed of 53.87 Mbps across local networks. No VPN blocking has been reported for this eSIM type.

Yes, Vietnam requires foreign visitors to register their passport or ID with the network for any SIM, including eSIMs. This registration is handled automatically during activation by your provider, so you do not need to visit a store, but your details must match your travel documents.
