Ghana's regulator has ordered American Tower's Ghana unit (ATC Ghana) to reconnect the power supply to the network equipment of Telecel Ghana.
It follows a dispute between ATC Ghana and Telecel, Ghana's second-largest carrier.
Connecting Africa reported network disruption last week for Telecel after ATC Ghana disconnected some of its sites.
ATC Ghana accused Telecel of failing to meet payment obligations for access to the sites.
"The non-compliance with the agreed obligations is such that ATC Ghana no longer has the capacity to buy electricity and diesel to maintain Telecel's equipment, especially when its agreements with Telecel have expired," ATC Ghana said in a statement.
This led the National Communications Authority (NCA) of Ghana to step in and instruct ATC to reconnect all Telecel Ghana sites by midday on July 6, and retract its statements about Telecel Ghana in the media.
In response to ATC Ghana's claims, Telecel hit back.
"Telecel Ghana reserves the right to use all lawful means to protect its brand and claim damages it will suffer as a result of the publications and any unlawful actions taken by ATC Ghana," the telco warned.
The NCA plans to hold future talks with both parties to ensure there's no repeat.
Telecel, which acquired a majority stake in Vodafone Ghana last year, has around nine million mobile customers in Ghana.
ATC has had similar disputes in other markets, notably in Kenya with Telkom. In December, ATC Kenya demanded payments of $3.26m and $978k per month from Telkom Kenya to turn back on mast sites it switched off last year.
