Hi folks...just picked one of these phones up used...the Consumer Celluar variety- was able to unlock it via an eBay code buy for $2 for use on AT&T Straight Talk.
As an FYI, Consumer Celluar sells a black Flex Gel case/car charger combo Accessory Kit for the Ascend Mate 2 for $15. It's available through the Consumer Cellular website and in some Sears stores - I found a couple of Sears near me that had one in stock - it can also be ordered into KMart stores. It's a pretty standard rubberized case in flat black but it does the basic job, and the port holes are in the correct places for the MT2-L03 American phones. I have some other Chinese cases coming for it and will likely pick up a Trident once I have the tempered glass in for it from China, as well as a belt case that was made to hold a Galaxy Mega with an Otterbox. Target sells the Consumer Celluar phone but I have not seen them sell the Accessory Kit. If you want a basic case fast that doesn't have to be modified this is an option.
