We build the eSIM we wished we'd had.
Six co-conspirators. Twelve carrier deals. One stupidly simple promise: land in Europe, already online.
Born from a €97 roaming bill.
In 2023, one of us took a five-day work trip from Amsterdam to Athens. The phone bill came back at €97. For checking email.
That night we sketched out an eSIM marketplace on a napkin. Eighteen months later, Domintra was live across 30 countries — built by travelers, for travelers, with prices that don't punish you for crossing a border.
We're independent, profitable, and proudly registered in Estonia. No VC pressure to charge you €0.04/MB after your “unlimited” plan runs out.
A small team doing big distance.
Three rules we won't break.
No "from" prices that triple at checkout. No surprise overage. The price you see is the price you pay.
We only partner with Tier-1 carriers — the same towers your local friends use. No grey-market roaming hops.
eSIM didn't install? Wrong country? Phone too old? Full refund within 30 days, zero questions.
Come roam with us.
Get an eSIM for your next trip, or just say hi. We answer every email, usually within an hour.
