From 1 February 2016 Sri Lanka will enforce a common minimum retail voice call rate for on-net and off-net domestic voice calls, to support competition between large and small network operators. As reported by the Sri Lankan Daily Mirror, the Telecommunications Regulatory Commission (TRC) has scrapped an existing dual-rate structure for on-net and off-net voice calls, by raising the on-net rate and lowering the off-net rate. The TRC said the floor rate revision was made in response to submissions made by the [smaller] telcos and would only be applicable for new connections issued from the effective date.
For end-user tariffs with per-second basis billing, the new unified minimum voice call rate will be LKR1.80 (USD0.01) per minute for calls within Sri Lanka regardless of making on-net or off-net calls; previously the on-net rate was LKR1.50 and the off-net rate LKR2.50.
For end-user tariffs with per-minute basis billing, the new common floor rate is LKR1.50 for calling all domestic phone numbers (previously LKR1.50 on-net, LKR2.00 off-net).
The SMS/MMS minimum charge was already a unified on-net/off-net LKR0.10 per message, but the TRC is raising this to LKR0.20 from 1 February.
Five mobile network operators are active in Sri Lanka, although the market leader Dialog Axiata accounted for more than 44% of all users at end-September 2015.
