Builds the supplier integrations and pricing behind SimFuse, and writes the connectivity news and roaming data here.
I founded SimFuse to sell travel eSIMs that work on arrival, in the countries people actually go to, without the roaming bill that used to follow them home.
Most of my work is the part nobody sees: the integrations with the wholesale networks we buy capacity from, the pricing rules that turn their rates into a plan you can understand, and the provisioning that has to deliver an eSIM in the seconds after you pay.
That is also why I write the posts here rather than commissioning them. When a regulator changes the rules for foreign eSIM sellers, I can tell you which plans are affected because I can see which connections they route over. When I publish a price per gigabyte, it comes from the same catalog the checkout charges against, not from a survey.
What I write about
Regulator decisions, network changes and border rules, when they change what a traveller should buy.
Price per gigabyte across the countries we cover, measured against our own catalog and republished as it moves.
Installing, activating and topping up an eSIM, written from the questions support actually receives.
