We’d just heard ZTE would be unveiling new quad-core 4G LTE devices at MWC in a couple of days, but did you know how well the company as a whole is doing? They’ve managed to achieve the ‘world’s-fastest’ sales revenue increase for Q1-Q3 of 2011. Prior to this growth spurt, ZTE’s sales revenue was a $6.87 billion for 2010.

And after a 33.4 percent increase for 2011, their revenue grew to $9.17 billion. I guess shooting for one of the top three handset providers by 2015 isn’t to farfetched after all. ZTE had always been quite aggressive at marketing their products in China, and their growth to other countries will be a test for success.

The ZTE Avail was released over on AT&T last November as a mid-range prepaid phone, and after seeing the many quad-core devices to be shown off at MWC – we would probably consider it entry-level now. Other than this device and a couple others, ZTE hasn’t reached out to the US as much as they probably could have. However, we will see the ZTE Mimosa X; the first smartphone powered by NVIDIA’s dual-core Icera 450 HSPA+ modem. We’ll find out more in a few days straight from ZTE’s stand at MWC.
