Configuring VPN on a Samsung devices I'm traveling in Iran and I would like to update my position on a website that uses Google Maps. The problem is that on my both Samsung Android devices I can't see the maps (the web site is not filtered and I can see everything but the map which is the main part of the application).  

I think that Google Maps is filtered although in some internet cafe I can use maps.google.com but I still can't see the map on my application (and other international web sites that use Google Maps).
Is there any way to configure a VPN network on my Android devices (a smartphone and a tablet).  

I don't know how it works and I can't access almost any tutorial (filtered)
. Thanks for any kind of help.
Last thing most of the time I use the wifi network in the rare hotel that have one.
Some VPN providers, such as HMA, have instructions specific to Android devices, so its best to check with your VPN provider via their support page, as you're going to need their server and other info. All android devices support PPTP VPN, and there are some VPN's you can use for free such as Hideman which you can find in Google Play. 

Here is a tutorial on basic configuration
