Thailand's telecoms regulator has ordered all of the country's telcos to stop providing broadband and mobile Internet connections to Cambodia.

As reported by the Bangkok Post last week, the National Broadcasting and Telecommunications Commission (NBTC) has given the orders as part of plans to clamp down on call center scammers and cybercrime.

As part of the measures, the telcos are required to report their SIM card sales to the NBTC every 15 days.

It comes amid heightened tensions at the border between Thailand and Cambodia.

Earlier this month, Cambodia's PM Hun Manet told officials to cut Internet and electricity services to Thailand.

But last week, Thailand hit back. The Bangkok Post reports that the Thai regulator has focused its campaign in the border area around the Khlong Luek crossing in Aranyaprathet district of Sa Kaeo.

The regulator has noted that all data and voice communication would be cut off in areas near the border within 15 days, with services reduced or restricted in areas farther away.

In total, 14 Thai companies offer broadband Internet in Cambodia.

Following a meeting last Thursday (June 26), regulators made the decision to order operators to cut off all signals to Cambodia.

If telcos do wish to provide services to Cambodia, they must produce evidence of the purpose and indicate the nature of the business involved, said the regulator. This includes the bandwidth that is used.

Earlier this year, the NBTC told telcos that base stations within 50 meters (164 ft) of the border must remove their antennas, again in an effort to combat the issue around call center scams.

For base stations within 1,000 meters (3,280 ft), antenna height is limited to 15 meters (49 ft), while any base stations within 3,500 meters (11,482 ft) are limited to 30 meters (98.4 ft) in antenna height.
