T-Mobile's HTC One M7 is set to receive an over-the-air update tomorrow, September 10th, that will deliver Android 4.4.3 along with Wi-Fi calling enhancements. HTC's Mo Versi, the company's Vice President of Product Management, took to Twitter this weekend to deliver the news in his usual fashion.

T-Mobile has long supported Wi-Fi calling, a feature that lets users circumvent a poor mobile connection by tapping into their home network instead.
