T-Mobile's Android 5.0 Lollipop update for Sony Xperia Z3 will reportedly be rolled out before the end of May and will come with LTE Band 12 (700 MHz) support.

T-Mobile’s official website has listed both Sony Xperia Z3 (model No. D6616) and Xperia Z1s (model number C6916) as “T-Mobile Testing Software Version: Android 5.0 Lollipop.” Notably, in March, the handsets were reportedly showing a status of “Manufacturer Development,” writes Xperia Blog.
On the other hand, T-Mobile had stopped selling the Sony Xperia Z3 temporarily in April, indicating the arrival of the 2015 flagship. However, now, the Xperia Z3 is back and T-Mobile is offering it at a discounted price of $499.92. It's also available for $20.83 per month with a two-year contract. The Xperia Z1s can also be purchased as a certified pre-owned handset for $229.92, or $9.58 a month with a two-year contract.
