T-Mobile will almost certainly take the checkered flag for wireless growth this quarter as consumers continue to flock to the Un-carrier. 

The nation's third-largest wireless carrier said it added 1.6 million net total customers, with 774,000 critical postpaid phone subscribers, or customers who pay at the end of the month. Verizon added 295,000 such customers, while AT&T nabbed 69,000 customers. Sprint, which traditionally follows the pack, reports its results tomorrow. 

The results come amid a relatively quiet period for T-Mobile, which isn't looking to rock the boat as it awaits regulatory approval for its acquisition of Sprint. The combination of the two could shake up the industry, and potentially light a fire under its 5G deployment, but it's not a slam dunk that the deal gets the OK. 

"We continue to drive our business beyond expectations and despite the work underway to close the merger, we delivered our best financials ever in the third quarter," CEO John Legere said in a statement. 

T-Mobile's results come after its larger peers, Verizon and AT&T, reported a mixed bag of results. Both companies padded their numbers with a surge in connected devices like Apple Watch, which generate lower revenue.
