We’ve been wondering exactly which US carrier was going to be first to snag the Sony Xperia Z. No, we’re not talking about the Sony Xperia ZL , its less attractive younger brother which doesn’t feature Z’s weatherproofing or all-glass body. We’ve got our sights locked dead on the uber sexy Sony Xperia Z and according to this recent FCC filing, looks to be headed, where else, but T-Mobile.

The FCC documentation revealed the Z sporting T-Mobile specific AWS LTE bands, and even pentaband HSPA+ (meaning this should also work on AT&T’s non-LTE 3G/4G network). The filing also revealed support T-Mobile’s WiFi calling as well.

It seems T-Mobile has all their bases covered in 2013, with their affordable UNcarrier plans and offering heavy hitting devices like the Samsung Galaxy S4 , HTC One , Nexus 4 and now the Sony Xperia Z — all without contracts (sorta). If I was Verizon or any of the other “top 3,” I’d be shaking in my boots right now.
