The Telecommunication Regulator of Cambodia (TRC) has warned mobile operator Smart Axiata that it could face legal action for attempting to entice customers away from rival Cambodia Advance Communications (CadComms, operating under the brand qb), The Cambodia Daily writes, citing a letter from the watchdog to Smart. The letter, dated 19 May and signed by TRC chairman Mao Chakrya, was sent the same day that the Phnom Penh Municipal Court ordered Smart employees and partners to cut off contact with qb customers, and to cease advertising aimed at persuading subscribers to move away from qb. The smaller operator has accused Malaysian-owned Smart Axiata of damaging its reputation and financial interests, after the two firms agreed to terminate a long-standing agreement that allowed qb customers to roam on Smart’s network. Prior to the termination of the agreement, qb began receiving calls from customers stating that Smart was contacting them to switch to its own network. The letter tells Smart to immediately stop moves to poach qb customers and says it must resolve the issue with its rival. However, an unnamed source with direct knowledge of the proceedings said that qb will pursue civil and criminal charges against Smart because the larger operator had ‘jeopardised qb’s total shareholder investment… If they succeeded in what they set out to do, then qb would be [left] with no customers and no revenue’.
