There are many reasons why you should look into getting a VPN subscription. The biggest one, is being able to use services that aren't available, or blocked in another country. For instance, if you travel to China a lot, or just travel a lot period. One good example of using a VPN is last week when I was in Barcelona. I couldn't use Sling TV since it's not available in Spain. But if I had a VPN, I could have used it.
Right now you can get a lifetime subscription to VPN Unlimited for just $39. Which isn't a bad price at all, seeing as the normal price is $130, that's about 70% off the regular price. You can grab VPN Unlimited through the Android Headlines Deals Store here.
