Can you use Skype in the UAE?

Yes, VoIP ihas been banned in the UAE for a long time. It's available in Dubai's free zones but not in the country in general. The authorities say it's because Skype and the others don't have a licence to operate here but in reality it's to protect the huge revenues of the government-owned telco.

That said, over 80 percent of the combined Abu Dhabi/Dubai population is expats, so it follows that these foreigners need some way to communicate with their loved ones back home. So, there have ways to get around the block, that while not legal, are easy enough. You can create a VPN (Virtual Private Network) or you can access Skype through a proxy. 

Also, there are even Internet cafes that have the Skype application downloaded. Many expats living in the UAE use Skype, so if you have a problem when you arrive just ask around and see what sort of actions other took.
 

I use Skype in Abu Dhabi. I loaded it on in my home country and upgrade it when I'm on holiday. It works quite well, I get a good connection. The help page is blocked in the UAE.
