eSIMโOn Shop does not provide an unlimited data eSIM for Vietnam. Travelers who need a large data allowance can instead choose from the fixedโdata plans that are available. Example options include the 50GB 180 days plan priced at $112.50 USD, the 20GB 30 days plan for about $44.00โ$50.00 USD, and the 10GB 30 days plan, which costs roughly $26.83โ$30.50 USD. While these fixed plans provide a clear data budget, they may be more costโeffective for most users unless a very heavy data user requires continuous data use without a cap.
