Roaming4You eSIM Data Plans for Vietnam

Roaming4You does not provide a true unlimited‑data eSIM for Vietnam.
The plans titled “Vietnam Unlimited Data – X Days” give 1GB per day of high‑speed data; when the 1GB daily quota is reached, speed is reduced to 1000 kbps. Travelers who need more consistent high‑speed data can choose one of the fixed daily plans that offer 1GB per day for lengths ranging up to 300 days, or they can purchase additional credit as needed.

Roaming4You does not offer any Vietnam eSIM that includes a phone number or SMS capability. The provider’s plans for Vietnam are strictly data‑only. Travelers who need a local phone number for calls and messages can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but some destinations may block or restrict these services, so it is wise to verify that the apps you rely on are accessible in Vietnam before purchasing a plan.

Roaming4You offers 22 single‑country data plans for Vietnam and no multi‑country options. Twenty‑one of these plans are daily data‑cap plans that reset each day, while one plan is a fixed data‑cap plan. Prices run from about $1.20 to $360.00, and each plan provides a 1 GB data allowance that can be used within a validity period of 1 to 300 days.
