Relying on your home SIM card for international travel, especially in Greece, can lead to significant unexpected costs. Post-Brexit, many UK carriers like O2, EE, and Vodafone have reintroduced daily roaming fees, which can quickly accumulate. Similarly, US and Canadian providers typically charge premium rates for international data, calls, and texts. Opting for a WestESIM plan for Greece provides transparent, cost-effective, and high-speed data, allowing you to avoid these exorbitant roaming fees entirely and stay connected without worry.
