Will my existing UK (O2, EE, Vodafone) or US (AT&T, T-Mobile, Verizon) SIM card still offer free roaming in Greece, or should I use HotelESIM?

It's important to note that many home SIM cards, particularly from the UK post-Brexit, have reintroduced daily roaming charges for Greece, often ranging from £2-£6 per day. Similarly, US and Canadian carriers typically charge premium rates for international roaming, making incidental usage quite costly. HotelESIM offers a predictable and cost-effective alternative. Our plans are designed specifically for travelers in Greece, providing transparent data allowances without unexpected roaming fees, making it an ideal complement or backup to your hotel's Wi-Fi, or even a primary connection.
