Meet the expert writers behind HelloRoam Blog
Every guide on HelloRoam Blog comes from a writer who has used the eSIM, the carrier, and the country first-hand. Our authors are travel writers, expat residents, and connectivity researchers who test plans on the ground in the destinations they cover. Bios list each writer's home base, the countries they specialize in, and the publications they have written for. We update articles as carrier coverage shifts, prices change, or rules around tourist data plans evolve, and every update notes what was changed and why.
We do not run sponsored posts and we do not list affiliate links from carriers or competitors that we have not tested. When a writer recommends a plan, the recommendation is based on real network performance, real activation experience, and real travel use cases. If a plan disappoints, we say so. Browse the authors below to find a writer covering your destination, your travel style, or your home region. Each profile links to the articles the writer has published, so you can review their work and professional background before you trust the advice.
