ARANYAPRATHET, SA KAEO: Representatives of the three largest mobile phone operators on Saturday visited the notorious Chinese "click farm" in this border province in a further attempt to verify the origins of some 300,000 SIM cards used in the operation.

The trip was arranged by telecom regulators who have been asking a lot of questions since the discovery on Monday of an operation used to boost likes and shares in Chinese social media to spur online sales.

For security reasons, especially after bombings triggered by mobile phones mainly in the South, all SIM cards in Thailand must be registered using ID cards or passports once they are activated. However, there is no limit on how many SIMs a person can own.
