US telco AT&T is pushing to sell its Mexican unit and exit the market just over a decade after entering the country.

As reported by Bloomberg, the US carrier is in talks with advisers to sell the unit for more than $2 billion.

The company wants to exit the market after struggling to take market share from Carlos Slim's Telcel.

AT&T entered the market back in 2014 after acquiring Grupo Iusacell SA for $2.5bn, before snapping up the Mexican business of NII Holdings a year later for $1.9bn.

Despite this, the carrier's market share in the country is around 18 percent, which is significantly behind Telcel, which commands around 64 percent.

Bloomberg reports that AT&T has invested more than $10bn in the market in the past decade.

The company hasn't commented on the reports, but has publicly outlined its fiber ambitions in the past 12 months in the US.

Following its announcement that it will acquire Lumen's mass market fiber business for $5.75bn, AT&T increased its fiber rollout to approximately 60 million total fiber locations by the end of 2030.

CEO John Stankey initially said the telco plans to reach more than 50 million fiber locations by 2029.

AT&T isn't the only telco pushing to exit the Mexican market. Spanish giant Telefónica also wants to leave the market, and is reportedly in exclusive talks with Beyond ONE, the owner of Virgin Mobile Mexico, to sell the unit.
