I was very close to buying an 830 unlocked at the MS store. In 2012 I bought the Lumia 920 for $449, I later unlocked and brought it to T-Mobile. I get LTE and 3G. I was very surprised that the 830 is more than the 920, when the 830 in many ways is inferior to the 920. The 920 was a 2012 flagship, while the 830 does have a removable battery, micro-sad slot, it's way overpriced. I am looking for a 830 Compatible with T-Mobile bands, where can you find one outside of Amazon/eBay. I checked out newegg and couldn't find one. Any help or direction would be much appreciated.
