Roamify eSIM Data Plans for Vietnam

Yes, Roamify offers unlimited data eSIM plans for Vietnam. The plans range in price from $3.00 USD for a 1‑day pass up to $26.00 USD for a 30‑day subscription, with validity periods that span from 1 day to 30 days. Each plan is marketed with a “Unlimited” data cap, available in several regions of Vietnam.

All unlimited options include a fair‑usage policy, meaning that while high‑speed data is provided initially, speeds may be throttled after heavy usage. Tethering is allowed on these plans, and the maximum speed offered is 4G, 5G, or LTE depending on local network availability. If you have concerns about potential speed reductions or about how much data remains at normal speed after a certain threshold, it is advisable to contact Roamify directly for confirmation.

Roamify does provide eSIM plans for Vietnam that include a phone number and SMS capability. The plans range from $10.00 USD for a 5‑day, 20GB data package up to $105.00 USD for a 365‑day, 20GB data package, with intermediate options available for 7‑day, 10‑day, 15‑day, 30‑day, 60‑day, and 180‑day validity periods. All Vietnam‑specific plans use a dialing code of +1, which is a U.S. code; thus the phone number assigned to travelers will be a U.S. number rather than a local Vietnamese number. Calls and messages can be made and received because the voice and SMS services are marked as inbound/​outbound. Travelers may wish to confirm any specific requirements with Roamify before purchase.

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.
