RedEx eSIM does not provide a true unlimited data eSIM for Vietnam. All plans listed as “Unlimited Data” give a specific data allowance—such as 1 GB, 2 GB, 3 GB, 5 GB, or 6 GB per day—before the connection speed decreases to a reduced rate (for example, 128 KBPS or 384 KBPS). If a user needs a higher data volume without a strict cap, RedEx eSIM offers fixed plans, such as 100 GB for 365 days or 50 GB for 3 or 5 days, which eliminate the speed throttling and can be more cost‑effective for heavy data users.
RedEx eSIM offers Vietnam eSIM plans that include a local phone number and SMS capability. The available plan contains 20 GB of data, 15 outbound calls, and 50 inbound and outbound SMS for 30 days, priced at $35.89 USD. The phone number assigned to the plan uses the dialing code +61 (Australia) in the first two variants and +971 (UAE) in the third; each number supports both inbound and outbound voice calls and inbound and outbound SMS. Users who need a specific calling or messaging function should confirm the details directly with RedEx eSIM.
RedEx eSIM offers 47 single‑country plans that are focused specifically on Vietnam, and 411 multi‑country plans that include Vietnam as part of a broader region. The single‑country plans vary from a basic 100 MB package to a 100 GB offer, while the multi‑country options range similarly but allow the user to roam across several destinations. Prices for Vietnam‑only packages start around $0.89 for the smallest data bundles and can climb up to roughly $545.92 for the most generous 100 GB, 365‑day plans.
The provider’s catalog also distinguishes between daily data cap plans and fixed data cap plans. Daily data cap packages give a set amount of data that renews each day (useful for short stays or burst usage), whereas fixed data cap packages allocate a total quantity of data to be used over the plan’s validity period (suitable for longer trips). Both types are available within the ranges listed above.
