iRoamly eSIM Data Plans for Vietnam

iRoamly does not provide a truly unlimited data eSIM plan for Vietnam. All of iRoamly’s listed plans for the country have a fixed data cap of 500GB. Because the plans carry a “Unlimited” label but have a finite data allowance, the speed will be throttled once the 500GB limit is reached.

Travelers can choose from several fixed‑data options instead. For example, iRoamly offers a 500GB plan that is valid for 1 day for US $4.00, a 500GB plan that is valid for 3 days for US $10.00, and a 500GB plan that is valid for 30 days for US $91.00. These 4G plans give a predictable amount of high‑speed data and can be more cost‑effective than an unlimited‑cap‑style plan if a user’s data needs are not extremely high.

iRoamly does not provide Vietnam eSIMs that include a phone number or SMS capability. Only data‑only plans are offered for Vietnam, so travelers cannot receive phone calls or text messages directly on their local number. To communicate while in Vietnam, popular VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection and can be used for calls and messaging without a phone number.

The provider offers 73 single‑country plans and 57 multi‑country plans for Vietnam. Prices range from free to about $257, while data caps span from 500 MB up to 500 GB. Plans are offered in two basic styles: a fixed data amount and a daily data cap; the former totals 76 plans, while the latter consists of 54 plans.
