Last year it was announced that the Surface 3 would be sold by companies like Verizon and, you guessed it, T-Mobile, by as soon as August of 2015. Well we're well into the year 2016 and I haven't heard a word about the Surface 3's on T-Mobile. I'm guessing that the relationship between T-Mobile and Microsoft isn't very good right now, for whatever reason, so I'm not counting on Surface 3's to be popping up in T-Mobile stores anytime soon, unless there's someone here more informed about this than I am.
So since I want (or is it "need") a Surface 3 with LTE capability I was wondering if it would work to use an unlocked Surface 3 with LTE with a T-Mobile data plan? I know that the new Microsoft Lumia phones (which I covet) such as the 950 and 950XL (did I say covet?) have issues with the T-Mobile network (or is it the other way around), and one of those problems is with a certain band of LTE. I think it was band 12 if I'm not mistaken. I don't know what all that means, so this is why I'm asking. I'd hate to spend hundreds of dollars on a product and begin a data plan that's all doomed to failure.
I was tempted to just buy an iPad Pro from T-Mobile. But I need to replace my 11 year old laptop, and something as portable as a tablet would be nice. There are several reasons why I can't use the iPad Pro. For one, I need to be able to manage my files. Hence, I need a file manager. So Android? Well I also I need to be able to use thumb drives and be able to connect to printers and other computers and cameras and external hard drives. The Apple and Android devices just wouldn't work for my line of work, no matter how good they be. If I buy an Apple or Android tablet I'd have to buy another laptop. And if I have to buy another laptop and am seeing I now need mobile 4G LTE data, I'd have to buy two plans. And since I wouldn't be able to do everything I want on an Apple or Android tablet, I'd be wasting money getting one.
On the other hand, I was thinking of just getting a Surface 3 with perhaps a mobile Wi-Fi device from T-Mobile. But that's not quite as handy since I only need internet for one device. My Lumia 925 from T-Mobile already has 4G LTE. So with the hot-spot device I'd have to worry about charging and carrying around two devices. Add my phone and that now becomes three devices. Not that it can't be done, but is this really my best choice?
So can you help me? Would there be any issues using one of Microsoft's unlocked Surface 3's with LTE on my favorite network, T-Mobile? Many thanks in advance!
