Simsima for Vietnam FAQ
Does Simsima offer unlimited data eSIM for Vietnam?
Simsima does not provide a truly unlimited eSIM plan for Vietnam. The plans titled “Unlimited” give a daily high‑speed allowance of 3 GB; once the daily threshold is reached the speed drops to 1000 kbps. Travelers who need more high‑speed data can choose from fixed‑data plans offered by Simsima, such as a 100 GB plan valid for 180 days or a 50 GB plan valid for 90 days, among other options. Fixed plans can be more cost effective unless a user requires very heavy data usage.
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. Some plans use a fixed data allowance that lasts for the full validity period, whereas others reset each day, offering a daily data cap; this difference allows customers to select a plan that fits either short‑term bursts of usage or longer, consistent consumption.
