The US government claims that mobile phone network, T-Mobile has agreed to pay $40 million fine over false ringtone accusation when calls couldn’t connect in rural areas. The Federal Communications Commission stated that the mobile network approved that it had inserted false ring tones into millions of calls.

The Federal Communications Commission also requires T-Mobile to implement a “compliance plan” to improve address the issues. The company stated that the issue was accidental and had been fixed in last January.

The Federal Communications Commission Chairman, Ajit Pai said, “It is a basic tenet of the nation’s phone system that calls be completed to the called party, without a reduction in the call quality—even when the calls pass through intermediate providers.” Further, he added, “The FCC is committed to ensuring that phone calls to all Americans, including rural Americans, go through.”

The agency banned false ringtones in 2014. The problem of false ringtone seems like a person trying to call someone in a rural area, would hear different rings and inopportunely assume the other party was just unable to answer the call. The agency was examining T-Mobile for violating rules it introduced in 2013 to improve phone coverage for rural areas.

T-Mobile said in the statement, “Our actions have always been focused on better serving our customers and the ringtone oversight, which was corrected in January 2017, was unintentional.” Further, it added, “We have settled this matter and will continue to focus on our mission to change wireless for good for consumers everywhere.”
