Viettel and travel eSIM in Vietnam

Viettel in brief

Viettel is a mobile network operator in Vietnam, and one of the networks a travel eSIM may reach through roaming. From the information we track, it runs 4G and 5G.

The plans on our shelf that name Viettel

From the supplier record behind each package, 63 of the 78 plans we currently sell for Vietnam declare Viettel as a network the profile can reach, at 4G and 5G. The figure comes from the same catalogue that prices the plan pages, not from marketing copy, and it moves when the supplier revises the record.

Why plans do not name a fixed network

Nearly every travel eSIM is a roaming product. The supplier holds agreements with one or more networks in the destination, and your profile picks between them by a priority order set inside the profile, not by the buyer. Two travellers on the same plan can end up on different networks in the same city.

The other networks in Vietnam

Alongside Viettel, the market also has MobiFone, Vinaphone, any of which your plan may use depending on the supplier.

• If signal is weak in one spot, try manually selecting another network your plan supports
• This market has 5G in parts of it, mostly in larger cities
• Leave data roaming on for the eSIM profile: roaming is how the travel plan works, not an extra charge
