Does CoreESIM confirm free roaming in Poland for UK or US physical SIM card holders?

CoreESIM clarifies that Poland, as an EU member state, applies "Roam Like at Home" (RLAH) regulations exclusively to EU citizens. For UK and US physical SIM card holders, the situation differs significantly. Post-Brexit, many UK carriers (e.g., O2, Vodafone UK) have reinstated daily roaming charges. US carriers (e.g., AT&T, Verizon) typically offer international roaming packages or charge high pay-as-you-go rates. CoreESIM offers a predictable, cost-effective data solution that bypasses these variable and often expensive roaming fees, providing clarity on your connectivity expenses in Poland.
