I'll soon be transiting twice through Dubai Airport Terminal 3 and would like to make a quick Skype video call back home while there. What are my options, free or paid? I'm open to wifi, Internet kiosks, local SIM, anything that gets the job done and doesn't cost an arm and a leg (read: roaming mobile data).

The always useless official DXB website claims "reliable and fast" free wifi, but the last time I passed through (Dec 2012) it was flakier than a Kelloggs factory, to the point of being impossible to even send an email, much less stream live video. Personal recent experience of it being usable at DXB peak hours (middle of the night) would be welcome though!
