Will my UK or US SIM card incur roaming fees in Spain, or is HotelESIM a better choice?

When traveling to Spain, understanding your home SIM card's roaming policy is crucial. For guests from the UK, most carriers have reintroduced daily roaming charges post-Brexit, even within the EU. Similarly, visitors from the USA or other non-EU regions will almost certainly face significant daily roaming fees from their providers. HotelESIM offers a straightforward, pre-paid data solution, eliminating the guesswork and preventing unexpected charges. It's a reliable option to ensure continuous connectivity, serving as a perfect backup to your hotel's Wi-Fi while exploring Barcelona or Madrid.
