RoameSIM eSIM Data Plans for Vietnam

RoameSIM lists several plans under the “Unlimited” label for Vietnam, but each of these plans actually provides 3GB of high‑speed data per day. After that daily 3GB limit is reached, the connection speed is reduced to 1000kbps. Because the high‑speed data allowance is capped, these plans are not truly unlimited in the sense of offering continuous high‑speed data without restrictions.

For travelers who need a higher data budget without daily limits, RoameSIM offers fixed data plans such as the 100GB plan valid for 180 days at $124.60 USD or the 20GB plan valid for 30 days at $40.60 USD. These alternatives can be more cost‑effective for users who expect to consume large amounts of data during their stay in Vietnam.

RoameSIM offers eSIM plans for travelers in Vietnam that include a phone number and SMS capability. The plans range in price from $21.00 USD for a 1 GB data allowance valid for 7 days up to $124.60 USD for a 20 GB data allowance valid for 365 days. Each plan provides a local dialing code of +1 and allows both inbound and outbound voice calls as well as inbound and outbound SMS messages. For the most accurate details on specific features or requirements, users should confirm directly with RoameSIM.

RoameSIM offers 12 single‑country data plans that cover Vietnam exclusively, and 34 multi‑country plans that include Vietnam as part of a larger region bundle. Across the entire catalogue the plans range from about $2.40 to $208.60, with data caps spanning from 200 MB up to 100 GB. The single‑country options include both daily data‑cap variants—where a fixed amount is allocated each day—and fixed data‑cap variants that grant a set amount for the entire validity period. The multi‑country set similarly mixes daily‑cap and fixed‑cap choices, allowing travelers to choose a plan that fits whether they need predictable daily usage or a larger bulk amount over a longer stay.
