AT&T has been rumored to be using Verizon towers for some time now, but the company has never confirmed or denied the claims. It is possible that AT&T is using Verizon towers in some areas, but it is also possible that the company is using its own towers.
AT&T has not commented on the issue.
If AT&T is using Verizon towers, it would make sense because the two companies are partners. Verizon owns a large part of the wireless infrastructure in the United States, and it is possible that AT&T is using Verizon towers to get better coverage in some areas.
However, it is also possible that AT&T is using its own towers. The company has invested a lot in building its own infrastructure, and it may not want to use Verizon towers.
It is also possible that AT&T is using Verizon towers in some areas and its own towers in others.
Overall, it is difficult to say for sure whether AT&T is using Verizon towers or not. However, it is possible that the company is using Verizon towers in some areas.
