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.
Frequently Asked Questions
Does ByteSIM offer unlimited data eSIM for Vietnam?
ByteSIM does not provide a truly unlimited data eSIM for Vietnam. The plans named “Vietnam Unlimited Data” are capped at 1 GB each day; once that daily limit is reached the speed is reduced to 10240 kbps. Because of this restriction the coverage is only considered “unlimited” in name, not in actual data allowance.
For travelers who need larger data allowances, ByteSIM does offer fixed‑data alternatives. For example, a 50 GB plan is available for 3, 5, 7, 10, or 15 days, giving a consistent high‑speed experience without the daily cap and throttling that applies to the “Unlimited” plans. These fixed plans can be more cost‑effective for most users who are not extremely heavy data consumers.
Does ByteSIM offer Vietnam eSIM with phone number and SMS?
ByteSIM does not provide a Vietnam eSIM that includes a local phone number or the ability to send or receive SMS. The provider offers only data‑only eSIMs for the country, so travelers cannot use traditional voice or text services on the Vietnamese network. If messaging or voice communication is needed, popular VoIP applications such as WhatsApp, Telegram or iMessage can be used over the data connection, allowing calls and messages without a Vietnamese phone number or SMS capability.
How many data plans does ByteSIM offer for Vietnam?
ByteSIM currently offers 89 single coverage data plans specifically for Vietnam. These plans range in price from approximately $2.90 to $69.90 and provide data allowances from 500MB to 50GB. They also offer a variety of plans with differing validity periods, from 1 to 30 days. Within these options, 56 plans feature a daily data cap, while 33 plans offer a fixed data allowance. No multi-country plans covering Vietnam are currently available from this provider.
