FAQ
Can I use my eSIM as a hotspot in Greece?
It depends on the provider. BNESIM and Nomad generally allow tethering. Holafly limits hotspot to 500MB/day on some plans. Airalo varies by plan. Check before purchasing.
What about "unlimited" data plans?
No travel eSIM offers truly unlimited high-speed data. Holafly's "unlimited" may throttle after ~5GB/day fair use. For most travelers, a 10-20GB fixed plan is more predictable and cheaper.
Which provider for island-hopping in the Cyclades?
BNESIM on Cosmote is the best choice for the Greek islands. Holafly unlimited is good for heavy users. Avoid providers with limited island coverage if visiting remote islands.
Do I need a VPN in Greece?
Greece has no significant internet restrictions. A VPN is generally not needed for travelers.
