A short FAQ for visitors
What devices work with an eSIM?
Most newer smartphones support eSIM, but it’s worth a quick check of your device’s settings or manufacturer site before your trip to confirm compatibility.
Will coverage hold up outside the city center?
Travel eSIMs run on established national networks, so coverage tends to stay solid across Brno and into the surrounding countryside for typical browsing and navigation.
Is it cheaper than paying for roaming through my home provider?
In most cases, yes. Roaming packages from home carriers are usually priced at a premium compared with a dedicated travel eSIM plan built for short visits.
