Roamify eSIM Data Plans for Vietnam

Roamify offers several unlimited‑data eSIM plans for Vietnam. The plans range from 1 day to 30 days of validity and cost between US $3.00 and US $26.00, depending on the chosen duration. Each unlimited plan uses 4G, 5G, or LTE networks and states that speeds may be throttled; normal speed could be capped at the maximum rate listed.

If you need certainty about how much data you can use at full speed, contact Roamify to confirm whether a Fair Usage Policy applies and what the typical data allowance is before heavy throttling.

Roamify offers several eSIM plans that include a phone number and SMS capability for use in Vietnam. The plans data cap from 1GB up to 20GB, with validity ranges from 5 days to 365 days. Prices start at $10.00 USD for a 20GB 5‑day plan and go up to $105.00 USD for a 20GB 365‑day plan, giving travelers a range of options depending on their travel length and data needs.

Each of these plans provides a phone number that uses the +1 dialing code, which means the number originates from the North American Numbering Plan rather than a local Vietnamese number. Voice services allow both inbound and outbound calls, and SMS services allow both inbound and outbound messages. Travelers should confirm the exact features and any potential restrictions with Roamify before purchasing.

Roamify lists 36 single‑country data plans that cover only Vietnam, while there are 111 multi‑country plans within which Vietnam is included. The single‑country options begin at about $3 USD for 1 GB and go up to roughly $160 USD for unlimited data, with validity periods ranging from 1 day to 365 days. The multi‑country plans cover the same price and data ranges and also include the same one‑to‑year validity, though they are tailored for travel across several destinations and may offer additional features such as tethering support.
