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.
