Roamify eSIM Data Plans for Vietnam

Yes, Roamify sells several unlimited data eSIM plans that work in Vietnam. The plans range from 1 day to 30 days in validity, with prices from $3.00 USD for a 1‑day plan to $26.00 USD for a 30‑day plan. All of these plans include tap‑to‑tethering and allow use on 4G, 5G, and LTE networks, but the speed may be throttled after exceeding normal usage levels.

Because an unlimited plan is subject to a Fair Usage Policy, speeds can be reduced after heavy use. If you are concerned about how much data remains at normal speed, contact Roamify directly to confirm the specific FUP limits and typical data allowance at full speed.

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.

The data set provided lists overall ranges for all eSIM plans but does not break down prices or data caps by individual provider or country. Because the information for Roamify’s specific offerings in Vietnam is not included, the exact count of single‑country and multi‑country plans available from Roamify for that country cannot be determined from this data set.
