Is roaming free in countries like Albania with my European or US SIM card, or is a WestESIM a better option?

Generally, no. Since countries like Albania are not part of the European Union, the 'Roam Like at Home' policy does not apply for most UK, EU, or US carriers. Relying on your home SIM card in such regions can lead to substantial and unexpected roaming fees. For cost-effective and reliable connectivity in destinations like Albania, a dedicated WestESIM is the optimal choice, ensuring you stay connected without incurring exorbitant charges, whether you're in Tirana or along the coast.
