A South Korean court acquitted the country’s three mobile operators – SK Telecom, KT and LG Uplus – of charges of violating a ban on excessive subsidies, Yonhap news agency reported.

The Seoul Central District Court said the mobile operators were not guilty of violating the Mobile Device Distribution Improvement Act, saying the prosecution failed to provide sufficient evidence.

Three operators and former board members of the companies who were indicted were cleared of all charges, Yonhap said.

Prosecutors indicted the three companies in April for paying subsidies over the limit to retail stores to attract customers when the iPhone 6 was launched in late 2014.

It was the first time the operators have faced charges and a trial since the new law, which limits subsidies to KRW300,000 ($258), went into effect in October 2014. The country’s operators have repeatedly fallen foul of subsidy regulations.
