No, roaming in the UK with an EU SIM card is generally not free post-Brexit. The UK is no longer part of the EU's 'Roam Like at Home' (RLAH) regulatory framework. Consequently, most EU mobile network operators (e.g., Orange France, Telekom Deutschland, Vodafone Spain) now impose international roaming charges for data, calls, and texts when their subscribers are in the UK. These fees can be substantial. A CoreESIM UK plan offers a cost-effective and predictable data solution.
