They're all in our latest picture postcard from this year's MWC jamboree, that's what!
Click on the photo below to get the pics rolling.
All photos, but none of the accompanying captions, by Siqui Sánchez/Getty Images, except for the Bharti Airtel Ltd. (Mumbai: BHARTIARTL) picture, which came direct from the operator.
You can get all the news, video interviews and pics from Barcelona during the event at our Mobile World Congress Show Site.
