According to GSMArena.com, a new Lumia device has been spotted in the wild and at the FCC. The Nokia RM-1090/RM-1091 is a dual-SIM Windows Phone device the size of the Lumia 830.
According to the FCC reports in measures 139.9 x 71.1mm. AdDuplex spotted the unofficial device in its logs and reports that the screen has qHD resolution (540 x 960). That would be a first for the Lumia line as current devices have (F)WVGA, 720p/WXGA or 1080p.
AdDuplex reports most hits came from China and Taiwan, though that’s not necessarily the target market, it could be just where the testing takes place. The Lumia handset has GSM and 3G with HSPA connectivity (no LTE, at least on the dual-SIM), Wi-Fi and Bluetooth LE, all of which comes together for a mid-range device. This device will likely be a hit in Nigeria due to its Dual Sim capability.
