While Gibraltar is a British Overseas Territory, it is not considered part of the United Kingdom for cellular roaming purposes. Post-Brexit, many UK carriers, including major providers like O2, EE, and Vodafone, have explicitly excluded Gibraltar from their free-roaming zones. Expect to incur expensive 'Day Pass' charges or pay per MB for data usage. DataESIM provides a more cost-effective and predictable data solution for your time in Gibraltar, avoiding these punitive roaming rates.
