eSIM vs Roaming in Vietnam
Roaming through a home carrier in Vietnam tends to be expensive, making it an unattractive option for most travellers. However, the travel-eSIM market in Vietnam is highly competitive, and travel eSIMs typically offer the cheapest and easiest solution for visitors seeking mobile connectivity during their stay.
Alternatively, travellers can purchase a local SIM or eSIM directly from one of Vietnam's carriers, which offer 3G, 4G/LTE, and 5G coverage. Since major local carriers issue eSIMs, this option is readily available and may also provide good value. For most visitors, comparing travel-eSIM deals with local options will help identify the best fit for their needs and trip duration.
| Option | When it tends to win |
|---|---|
| Home-carrier roaming | Short trips where convenience beats cost; check your carrier's day-pass. |
| Local SIM / eSIM | Longer stays if you can buy and activate locally — local carriers issue esims. |
| Travel eSIM (Airalo/Holafly/Saily) | Easiest all-rounder: install before you fly; works on modern eSIM phones regardless of local-eSIM support. |
