GulfData eSIM Data Plans for Vietnam

GulfData does not provide a true unlimited high‑speed data eSIM for Vietnam. The plans that carry the “Unlimited” label actually allow 1 GB per day of high‑speed data; once that daily limit is reached the speed drops to 512 kbps. Therefore, these plans are capped, not unlimited.

GulfData offers several fixed‑data alternatives that cover Vietnam. For example, a 20 GB plan lasts 30 days and costs $25.50, while a 50 GB plan is valid for 180 days and costs $87.50. These fixed‑data plans may be more cost‑effective, especially for travelers who need a large amount of data.

GulfData does not offer a Vietnam eSIM that includes a phone number or SMS capability. Travelers who purchase a GulfData plan for Vietnam will receive a data‑only eSIM that provides internet access but no native voice or text messaging service. They can still perform calls and send messages using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection; however, some destinations may restrict certain services, so users should check the accessibility of the apps they rely on in Vietnam before buying a plan.

There are 12 single‑country plans available when you select Vietnam, and 34 multi‑country plans that include Vietnam in their coverage. The plans span a price range from about $3.50 to $179.50 and a data allowance between 1 GB and 50 GB. Some plans lock a fixed amount of data for the entire validity period, while others provide a daily data cap that resets each day; choosing a fixed‑cap plan gives you a set volume for the plan’s duration, whereas a daily‑cap plan limits you to a certain amount each day, which can be useful for predictable usage.
