Will I incur roaming charges in Czechia if I'm using my UK or US SIM card, or is roaming free?

The situation with roaming in Czechia depends on your home country. For EU citizens, 'Roam Like at Home' generally applies as Czechia is an EU member. However, if you are traveling from the UK post-Brexit, many UK carriers (like O2, Vodafone, Three) have reintroduced daily roaming fees, which can quickly add up. For travelers from the US, international roaming charges are typically quite high. HotelESIM offers a transparent, prepaid data solution, allowing you to avoid these potentially expensive roaming fees and enjoy predictable costs.
