Greece-specific troubleshooting
Things that can go wrong in Greece.
- Ferry routes between islands have coverage within 8 km of shore — open-water stretches are offline.
- Meteora monastery interiors have weak signal due to stone construction.
- Santorini and Mykonos experience network congestion in August peak — this is a crowd issue, not carrier.
