Simsima for Vietnam FAQ
Does Simsima offer unlimited data eSIM for Vietnam?
Simsima’s eSIM plans that use the word “Unlimited” are not truly unlimited – each gives 3 GB of high‑speed data per day and after that limit the speed is throttled to 1000 kbps. Those plans are valid for 7, 10, or 30 days, so there is no continuous unlimited‑data option for Vietnam. Travelers who need a larger, sustained amount of data can choose from Simsima’s fixed‑cap plans, such as the 100 GB plan valid for 180 days or the 50 GB plan valid for 90 days; both maintain full speed throughout their duration.
Does Simsima offer Vietnam eSIM with phone number and SMS?
Simsima does not provide eSIM plans with a phone number or SMS capability for Vietnam; all of its offerings for the country are data‑only. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection, but it is advisable to confirm that these services are accessible in Vietnam before purchasing, as some destinations may restrict or block certain apps.
How many data plans does Simsima offer for Vietnam?
Simsima lists 10 single‑country data plans and 19 multi‑country plans for Vietnam, giving travellers a range of choices. Prices span from about $0.40 to $84.53, while data caps vary between 100 MB and 100 GB.
