I think you -- and others who haven't checked, which is understandable -- imagine that after Nokia sold their handset business to Microsoft, nothing was left but a tiny little husk. If that were true, your assumption would probably be correct, but it isn't. Nokia ended 2014 with over 60,000 employees worldwide and nearly €13B in revenue. They're still a really big company. Sure, they make some money from patent licensing -- as do all companies of that size -- but the vast majority of their revenue comes from network equipment and services.
Just because you can't see the Nokia logo on the cell towers and base stations doesn't mean we don't make them. I'll take physical evidence and a balance sheet over dumb stuff like this.
For example, If you use T-Mobile in some markets, that's Nokia-Siemens, if you use AT&T, thats also NSN, plus ALU - Verizon, ALU, Sprint, Samsung, Ericsson or ALU depends on market.
They make very very real, very expensive products.
