Missed calls and unknown calls.

TRC Warns About Unknown Calls. “We have received a fair number of complaints from telephone subscribers in Sri Lanka, of missed calls received from unknown international party. When subscribers returned the calls, the call charge for such calls have been excessive more than the normal call charges.

Some groups from certain countries are misleading in this manner to induce local subscribers to return such calls.
Furthermore, since interconnection charges for International calls are high, call charges for such calls by their nature are more.
We have made inquiries from telephone services providers in Sri Lanka and their responses were as follows: Mobitel (Pvt.) Ltd. Informed TRCSL that similar acts had happened previously and actions have been taken to block these number series before this event.

Sri Lanka Mobile Phone users.

Dialog Axiata PLC informed TRCSL that on receiving customer complaints, immediate steps were taken to block such international numbers. Mobile phone carriers like, Hutch, Airtel and Mobitel stated that they had not received many complaints from their subscribers, of such calls.

Telecommunications Regulatory Commission of Sri Lanka hereby notify all telephone subscribers in Sri Lanka.
Refrain from redialing calls to such unknown telephone numbers.
