Yes. AeriSIM sells unlimited data eSIM plans for Vietnam that are valid for 1 to 30 days. The 1‑day plan costs $1.97 USD, while the 30‑day plan costs $42.76 USD, with intermediate prices for 3, 5, 7, 10, 15, 20, and 30 days. All unlimited plans use 5G, allow tethering, and have a maximum speed of 10 000 kbps, but data usage may be throttled after a certain amount of consumption in line with AeriSIM’s Fair Usage Policy.
If a traveler wants confirmation of any speed restrictions or the typical amount of data that remains available at normal speed, they should contact AeriSIM directly to discuss the Fair Usage Policy and its impact on their usage.
