How much data do I need in Vietnam?

Light
1–3 GB
Maps, messaging, the occasional email. Great for short trips.
Standard
5–10 GB
Social media, navigation, sharing photos, some music — for 1–2 weeks.
Heavy
20 GB+

Not sure? Use the plan finder to find the right plan by trip length and data needs in seconds. If you run low, many plans can simply be topped up.
Network coverage & good to know
In Vietnam your eSIM automatically connects to the strongest available partner network — typically 4G/LTE or 5G in cities and tourist areas. Coverage can vary in very remote regions. After installing, enable data roaming for the eSIM profile (this is normal and incurs no extra cost — you're using your booked plan). Tip: install the eSIM over Wi-Fi before departure so you're online the moment you land.
In cities and tourist hubs 4G is strong; in the highlands (Sapa, Ha Giang) the signal can dip. Budget extra data for Grab ride-hailing and translation apps.
