ZTE unveiled the Grand Memo II LTE

Mobile World Congress is only a week away, but that hasn't stopped phone companies from unveiling what they have in store beforehand.

Case in point: ZTE unveiled that it will introduce a 6-inch handset at the tech conference, known as the Grand Memo II LTE. The device will serve as the successor to the Grand Memo, which debuted at last year's MWC.
Though not many details have been released, ZTE reported that the smartphone will be "ultra slim." The company will also be launching an update to its handset user interface, called MiFavor 2.3, so don't be surprised to see the Grand Memo II LTE running this UI as well.
ZTE also reported that it will showcase another Firefox smartphone called the Open C, which will launch with Firefox OS 1.3.
You can bet that CNET will be at the show, which takes place in Barcelona, Spain. Be sure to check back when MWC 2014 kicks off next week for upcoming information on both phones.
