Mexican telecoms services regulator Cofetel has proposed fines for three of the country's mobile phone operators for failing to advise customers when they will start being charged for calls that go to voicemail, the watchdog said in a statement.
In a joint press release along with the consumer protection agency Profeco, Cofetel said the proposed sanctions are against Telcel, Movistar, and Unefon, which is part of Grupo Iusacell. The regulator said tests showed that the three operators failed to implement a mechanism that allows users whose calls are not answered to hang up without charge before being forwarded to voicemail.
Cofetel also said the proposals were sent to the country's communications and transport ministry (SCT) for approval.
