How Unlimited Data Works in Vietnam
Vietnam Unlimited Data Plans provide unlimited mobile data in Vietnam with a high-speed data allowance for each 24-hour period. The amount of high-speed data is based on the selected plan level.
After the high-speed allowance is used, unlimited data remains available at reduced speeds until the next 24-hour period begins, when the high-speed allowance becomes available again. For full details, review the Fair Usage and Expiry Policy.

- Add a Vietnam Unlimited Data Plan. Choose the available plan duration that fits your trip. Most plan assignments are completed within minutes during business hours, but please allow up to 12 hours in rare cases.

Using Mobile Data During Your Vietnam Trip

- Business travel: Stay connected to email, browser-based services, messaging, video meetings, and other online tools while travelling.
- Hotspot and router use: Share your mobile data connection with another device or use the SIM Card in a compatible unlocked travel router.
Your Vietnam SIM Card can connect to supported partner networks including Mobifone [2G/3G], Viettel [3G/4G/5G], and VNPT (Vinaphone) [2G/3G/4G]. Network availability depends on your location, device, and local network conditions.
