The e-ink display and a two-way power switch are located at the top, where sliding the latter to the left will enable the Ruby to behave like a secure hotspot, while sliding it to the right, and it ends up as a public access point. The e-ink display itself shows off the battery and signal status, in addition to the number of connected devices and a smiley icon that confirms public mode. At the bottom edge would be a trick flap which doubles up as both a micro-USB socket and a USB Type A plug, depending on how one positions it. Pretty neat idea, no? As for the micro-SIM slot, it remains hidden right behind, The Yota Ruby supports quad-band EDGE, plus HSPA+ and LTE for the European market at this point in time, with a battery life of approximately 16 hours of non-stop use.
