File this one under rumor, with little else to go on, but @evleaks is reporting that T-Mobile is getting the Lumia 1525.
What is the Lumia 1525? That's a good question but no details were given in the diminutive tweet. It should seem obvious at this point that a 1525 would be a variant of the 6-inch 1080P Lumia 1520 that has been on the market for months now.
Seeing as the Lumia 1520 is exclusive to AT&T in the US, T-Mobile may be exercising their prerogative of getting their own exclusive version to differentiate themselves. Everything from a slightly redesigned body to more (or less) features are on the table, though if the rumor holds accurate, a six inch phablet Windows Phone should be gracing the budget friendly T-Mobile service.
Unfortunately, no time frame was given either for this Lumia 1525.
T-Mobile is no stranger to Nokia, often taking their own exclusive devices in the past e.g. the Lumia 810 and Lumia 521. T-Mobile has also taken off-the-shelf versions of the Lumias, including the Lumia 710 and Lumia 925.
Speaking of the Lumia 925, T-Mobile has recently halted new sales of that device, only offering refurbished ones instead. They have also announced the Lumia 635 as a new budget friendly Lumia, but that leaves a high-end Windows Phone missing from their lineup. Could the Lumia 1525 fill that void? We have not heard of a Lumia 1525 in the works from our sources, but anything is possible in these fast times. We'll just have to wait and see.
