Billion Connect does not currently offer an unlimited data eSIM for Vietnam. All available plans list a specific data cap, such as 100GB for the Orange World eSIM 1 Day 100GB or 50GB for the Vietnam eSIM 30 Days 50GB. Travelers can choose from these fixed‑data options, which provide a hard limit but can still be topped up if more data is needed.
For most users, a fixed data plan can be more cost effective, especially if the data usage is moderate to high. A 50GB 30‑day plan, for example, offers good coverage and speeds on the 5G network, while the 100GB 1‑day plan provides a large burst of data for short stays. Unlimited plans are not available from Billion Connect for Vietnam at this time.
