Is the wifi reliable enough for video calls in Ahangama.

Yes, the wifi in Ahangama is highly reliable for video calls, provided you stay at a dedicated coworking space or a modern boutique hotel. Places like Focus Hub and Mellow Hostel have invested in high speed Sri Lanka Telecom fiber optic connections. However, you should not rely on the free wifi at small beach cafes for important Zoom meetings, as those connections frequently drop.
