I use occasionally Hotspot Shield (https://www.macupdate.com/app/mac/27383/hotspot-shield). It works but it is, of course, not exactly fast and you cannot choose which server to use.... are there any free reliable vpn services that I can use ...
What? You mean there are illegal USAGES of VPN, because the technology itself isn't illegal. Any technology can be used for illegal purposes.The legality issue is one reason to use SSH instead of VPN, since it sometimes is perfectly legal whilst VPN isn't. And it's just as secure if set up that way. And cheap and reliable.
Forget about that, just google the differences between both, SSH and VPN, I think VPN is far superior but maybe for your needs SSH would be enough, getting a free VPN account is easier though.When and why is SSH legal when VPN is not?
Yeah, usage. Usually blocking certain sites. They sometimes block VOIP as well. Banana VPN, eg, has a list. Dunno how the countries accomplish it, or whether they'd hassle a normal business use going back to your office or whatever, but forewarned is forearmed, as they say.What?

I can highly recommend this option. I did this myself using OpenVPN and DuckDNS. Very happy with it too.Buy a Raspberry Pi for $35 and set it up on your home router. The 'Pi is a full Linux computer based on a little ARM chip. It's a single board and uses an SD card for a "hard disk."
Then set up VPN per http://unvexed.blogspot.com/2012/08/how-to-set-up-real-encrypted-vpn.html
...Worked great for me when I was in China. It allowed me to access services that are ordinarily blocked by the Great Firewall, along with stuff I needed for my work. And needless to say, you get all the VPN you want for the princely sum of $0, after the initial purchase of the 'Pi. And you can use the 'Pi for many things-- it's a complete computer. Add an HDMI monitor, a keyboard and a mouse, and you have a decent entry-level desktop machine to play with as well as a tidy little server. Or you can just use it as a server... mine runs the full LAMP stack plus the VPN and some other stuff. You'll need an old iPhone charger or something of the sort to power it. Needless to say, your electric bill won't notice its hunger at all, and the thing is stone-reliable.
Of course, there's some risk in that accessing the aforementioned services is illegal in some countries, including China. (Similarly, VoIP is illegal in many countries.) My own judgment for my case was that such laws are for the locals and not for visiting businessmen who routinely use VPNs to access company resources. But you will need to make your own estimation and decide for yourself; you may well come to the conclusion that it's not worth the risk. In any case you'd be wise to keep your VPN usage to yourself.
You want the Model B, which has an Ethernet port. Best price for the 'Pi for U.S. purchasers is at http://www.alliedelec.com/lp/120626rasomodelb/?mkwid=lRZmN5be&pcrid=2397047766&pkw=raspberry pi model B&pmt=e&utm_source=bing&utm_medium=cpc&utm_campaign=Raspberry+Pi+-+Updated&utm_term=raspberry pi model B Amazon has it too now: http://www.amazon.com/s/?ie=UTF8&keywords=raspberry+pi+model+b
The version with the ready-to-go 8GB SD card is the best bet for a newbie. If you decide to provide an SD card of your own, be sure it's on the compatibility table. You'll find that and much more information at http://www.raspberrypi.org
