Is roaming free in Poland with my UK or US SIM card, or would HotelESIM be a better option?

The concept of "free roaming" in Poland, an EU member, largely applies to EU citizens under "Roam Like at Home." However, for travelers from the UK (post-Brexit) or the US, the situation is different. Many UK carriers have reintroduced daily roaming fees, and US carriers typically charge high international roaming rates. HotelESIM offers a transparent, cost-effective alternative, providing dedicated data for Poland. It ensures you have reliable, budget-friendly connectivity, serving as an excellent complement or backup to any hotel WiFi without unexpected charges.
