AloOui eSIM Data Plans for Vietnam

AloOui does not provide a true unlimited data eSIM for Vietnam. All plans that carry “Unlimited” in their name actually grant a fixed high‑speed allowance—typically 1 GB per day or 2 GB per day—and after that limit is reached the speed is throttled to 512 kbps or 2 Mbps. For travelers who need more continuous high‑speed data, AloOui offers fixed‑data packages such as the 100 GB 30 day plan priced at $102.72 USD and a 100 GB 90 day plan priced at $278.82 USD. These larger fixed‑data options can be more economical for heavy data users compared to the high‑speed “unlimited” plans that include throttling after the daily cap.

AloOui does not provide Vietnam eSIM plans that include a phone number or SMS functionality. All available plans are data‑only. Travelers can still use VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection, but some destinations may restrict access to these services, so it’s wise to verify whether the apps you rely on are accessible in Vietnam before purchasing.

AloOui offers 29 single‑country data plans that cover Vietnam on their own, and 62 multi‑country plans that include Vietnam among other destinations. The single‑country catalogue contains both fixed‑data‑cap options, where a set amount of data is available for the plan’s validity period, and daily‑cap plans that limit consumption each day. Prices for these plans run from roughly $5 to $490 USD, while data caps range from 1‑gigabyte to 100‑gigabyte offers, giving customers a wide range of choices to suit different usage needs.
