Cambodian mobile telecoms operators have been ordered to submit to their cost data to the country’s telecoms regulator from this month, following a move to remove minimum pricing. The government nullified a law in November which set minimum prices on telephone calls - following protests from customers on social media. A statement said: ‘All telephone operators have to submit to the TRC  their cost base calculations every six months,starting from January 2014, for the regulator to have a basic principle to track honest competition.’
