Vietnam eSIM questions
Which networks does Roamy use in Vietnam?
Roamy plans for Vietnam run on Viettel Mobile, Vinaphone and MobiFone, with speeds up to 5G where the network offers it.
How much data do I need for a week in Vietnam?
About 1 GB a day covers maps, photos and the odd video call. For a week we recommend 10 GB for 30 days at $21.00.
When does my Vietnam plan start?
The validity period starts when the eSIM connects to a supported network. Install it before you fly; it waits until you land.
Is there a plan for Vietnam and other countries?
Yes. Asia and Global plans include Vietnam along with other countries. Each plan lists exactly which countries it covers.
Can I add more data later?
Yes, on most plans. Add data in the Roamy app and it goes onto the eSIM you already have, with nothing new to install.
