It is critical to note that most UK, EU, and Canadian 'USA Roaming' plans explicitly exclude Puerto Rico. Carriers such as Vodafone UK, O2, EE, or Deutsche Telekom often classify Puerto Rico under 'Caribbean' or 'Rest of World' roaming zones, incurring exorbitant pay-per-MB charges. CoreESIM provides a dedicated data solution for Puerto Rico, offering transparent, cost-effective data rates that prevent unexpected roaming fees and ensure reliable connectivity.
