“Bought their Vietnam eSIM with Viettel number. Was extremely good. I believe it's exactly the same as prepaid Viettel SIM product available to tourists at the airport, just in eSIM form. Excellent Ping (below 50ms), fast speeds. Solid choice.”
“Super easy to purchase and activate eSim. Works great. Very affordable.”
ByteSIM does not have a truly unlimited data eSIM for Vietnam. The plans that include “Unlimited” in their name give 1GB per day; once that daily quota is reached the speed is throttled to 10240kbps. All other plans are fixed‑data packages. Travelers can instead choose from the available fixed‑data options. For example, a 50GB plan for 30 days costs $47.90, and a 20GB plan for 10 days costs $20.90. These plans may be more cost‑effective for most users, although very heavy data consumers might need to purchase additional or longer‑validity packages.
ByteSIM does not provide Vietnam eSIMs that include a local phone number or SMS capability; only data‑only plans are offered. Travelers can rely on VoIP applications such as WhatsApp, Telegram, and iMessage to make calls and send text messages over the data connection, removing the need for a local phone number or SMS service.
ByteSIM offers 80 single‑country plans for Vietnam, with no multi‑country options available. The plans range from about $2.90 to $69.90 and provide data between 500 MB and 50 GB over a validity period of 1 to 30 days. Some plans use a daily data cap, giving a specified amount of data each day, while others use a fixed data cap that applies for the full validity period. Tethering is allowed on applicable plans.
