Well, it seems like Lumia 635 and Lumia 630 story once again!!
Real-life images leaked ( Above ) in China claim that the earlier leaked LTE version of Lumia 730 will be called Lumia 735, while the Dual-Sim version will come as Lumia 730.
So, now we can safely confirm that the LTE variant and Nano-Sim of Lumia 730 which passed certification at FCC as RM-1038 will be called Lumia 735 and the Dual-Sim variant RM-1040 which we caught at FCC will be called Lumia 730. The Dual-Sim RM-1040 variant has passed certification in Indonesia too.
Read all about the Lumia 730 specs, features, pricing on our dedicated page. Both Lumia 730 and Lumia 830 will be announced by Microsoft Mobile on September 4 at IFA in Berlin.
Thanks NokiBar for the tip. Cheers!!
