yaySIM for Vietnam FAQ
Does yaySIM offer unlimited data eSIM for Vietnam?
No. yaySIM does not provide any plan that offers unlimited high‑speed data for Vietnam. Travelers can choose from fixed data plans that allow large amounts of data, such as the VN_50_180 plan which gives 50GB for 180 days on 5G, or the AS‑7_50_180 plan that also offers 50GB for 180 days but covers Vietnam and six additional countries. These fixed‑data options are typically more cost‑effective for most users, unless a traveler expects to consume data far beyond the plan’s allowance.
Does yaySIM offer Vietnam eSIM with phone number and SMS?
yaySIM does not provide Vietnam eSIM plans that include a phone number or SMS capability. All available plans from yaySIM for Vietnam are data‑only, and travelers will use the data connection for internet access rather than traditional voice or text messaging.
Travelers who need to make calls or send messages can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to confirm that the apps you intend to use work in Vietnam before purchasing a plan.
