All four of Ghana's mobile network operators have been fined a total of $7m (£5.4m) for failing to meet benchmark service requirements.

Frequent call drops, calls taking a long time to go through and poor sound quality were among the reasons Ghana’s National Communications Authority punished Vodafone, MTN, Glo and Airtel/Tigo.

The biggest fine of $2.4m was handed to Airtel/Tigo, Joy Online reports.

Consumers have told the BBC they have faith that the sanctions will result in improved services.

Worst affected are residents of rural Ghana who even have to climb trees or walk several kilometres to find sufficient network reception to make and receive calls.
