According to the Wall Street Journal, AT&T has walked away from a deal to sell China's Huawei smartphones in the U.S. Neither AT&T nor Huawei have commented on the matter, but the news is certainly going to disappoint those of you who were looking forward to picking up Huawei's flagship Mate 10. Prior to this report, Huawei was expected to announce that its flagship Mate 10 will launch on AT&T in 2018. PhoneDog reports: Huawei has a major presence internationally, with recent reports saying that it's the No. 3 smartphone brand in the world behind Apple and Samsung. The company hasn't made much of a dent in the U.S., though, despite the fact that it's been selling its phones unlocked in the U.S. for awhile now. This AT&T deal would've been big for Huawei, helping it to get its phones inside carrier stores and in front of U.S. consumers, the majority of which still buy their phones from their carriers. Now we'll have to wait and see if Huawei can strike a deal with another carrier or if it'll have to continue on in the unlocked market. A Huawei spokesperson only said "Huawei has proven itself by delivering premium devices with integrity globally and in the U.S. market."
