We got sick of paying
roaming bills.
So we built something better.
BoldSIM started with one traveller who got fed up.
Fed up with roaming bills that arrived weeks after the trip. Fed up with wrestling a SIM ejector tool at the departure gate. Fed up with queuing at a phone shop in a city where nobody spoke the same language, burning time that should have been spent exploring.
eSIM technology existed, but the services built on top of it felt clunky, overpriced, or just unreliable. So the decision was made to build the product that should have existed all along.
The idea was simple: pick your destination, get unlimited data, land and connect. No contracts, no SIM cards, no drama.
Today BoldSIM covers 190+ countries. The mission hasn't changed — build for the traveller who wants to be present in the world, not wrestling with their phone plan.

What we stand for
A few things we refuse to compromise on.
Built by travelers
Every feature we ship comes from a real frustration we've had on the road. If it doesn't make travel easier, it doesn't ship.
Instant everything
No waiting for a SIM in the mail, no hunting for a phone shop at the airport. Your eSIM is ready the moment you check out.
Fair pricing
Local rates, no surprise charges, no contracts. You pay for what you need and nothing more.
Always reliable
We partner with top-tier local carriers in every country so you get real coverage, not a best-effort signal on a third-tier network.
