Coverage in Sri Lanka

Dialog and Mobitel 5G coverage limited to major urban areas (Colombo, Kandy, Galle, Jaffna). Northern and Eastern provinces have sparser 4G coverage. Band B40 (TDD 2300 MHz) used by Dialog and Mobitel is absent from many North American phone models.

Common Questions

The details worth knowing about your Sri Lanka eSIM

Your eSIM connects to Dialog Axiata, Mobitel, Hutch, and Airtel. Dialog and Mobitel offer the widest 4G, but coverage turns sparse in the Northern and Eastern provinces. 5G is limited to central Colombo, Kandy, Galle, and Jaffna. Outside those cities, expect slower data or signal gaps.

Many North American phone models lack band B40 (2300 MHz), which Dialog Axiata and Mobitel use for 4G. Without it, you may drop to slower bands or lose signal in areas relying on B40. Check your phone’s band support for B1, B3, and B5 to be safe.

No. This eSIM is valid only within Sri Lanka’s borders. It stops working when you cross into the Maldives, India, or any neighbouring territory. You would need a separate eSIM or local SIM for those destinations.

Sri Lanka requires all SIMs, including eSIMs, to be registered with a passport. Our eSIM activation includes this registration using your ID details before travel. Without it, the eSIM will not connect to any local network upon arrival.

No throttling or content filtering is applied beyond standard network management. You get the full median download speed of 21.87 Mbps from local networks, subject to normal congestion. Streaming and VoIP work without blocks.
