About Viasimo
We sell data, not surprises.
Viasimo is a travel eSIM shop. Buy a data bundle for the country you are flying to, install it before you leave, and use your phone abroad at a price you agreed to in advance.
Why we started
Roaming bills are written to be discovered after the trip. A week of maps and messaging can cost more than the flight home, and the only way to find out is to open the statement.
An eSIM removes that. The price is fixed before you leave, nothing renews on its own, and your own number stays where it is. We built the shop we wanted to buy from: a country, a data size, a total, done.
What we promise
The price you saw is the price
One payment, shown as a total with tax before you confirm. No activation fee, no top-up trap.
Nothing renews on its own
When the data runs out, the bundle ends. You decide whether to buy again.
Your number keeps working
Calls and texts stay on your normal SIM. Viasimo only carries the data.
We say no when it will not work
If your phone or destination is not supported, support tells you before you pay.
How the price stays low
Same networks as the expensive options. Less overhead in between.
Local networks
We buy where you land
Bundles run on the same local networks the big carriers roam onto. You are not on a slower lane.
A light shop
No retail, no app to install
A web checkout and an email. That is most of the product, and it costs us very little to run.
Plain pricing
One price, passed on
No introductory rate that doubles later, no fees added at the last step. What we save, you pay less.
Editorial standards
How we keep our guides accurate
Our magazine exists to answer real traveller questions clearly, not to chase keywords. Every guide is written and reviewed by the Viasimo editorial team, leads with a direct answer, and carries a published and updated date because networks, devices and prices change. When something depends on your specific phone or plan, we say so rather than guess.
