Don't let the higher model number throw you, this is model is a mid-ranger from the Finnish OEM. Mobile ad network AdDuplex spotted this model (mostly in Taiwan) and noted that it has a screen resolution of 480 x 800 (WVGA). By definition these days, this would make the Nokia RM-941 a mid-range model at best.
The device shows LTE support for bands 20, 3 and 7 which means the device will support LTE outside of North America. In other words, there is no U.S. or Canadian LTE connectivity for this model. It does offer AT&T's GSM bands at 850/1900MHz. There is some speculation that with an estimated size of 128.6mm X 70mm, this could be a follow-up to the Nokia Lumia 720 which measures 127.9mm x 67.9mm.
Another possibility is that the FCC visitor is the rumored Nokia Lumia 625. You might recall that this was a phone that was expected to show up at the manufacturer's May 14th event although it never appeared. This model was tipped to have a 4.7 inch screen, but only 512MB of RAM. The phone was expected to launch with the GDR2 version of Windows Phone 8 pre-installed.
