Why pay for the internet in an internet café if you can use it for free via your mobile phone? You may think using the internet in foreign countries is expensive. And you could well be right. However, more and more Hostel owners start offering free Wireless internet to their customers.
The term Wi-Fi is often used by hostel owners to make clear that your stay includes the free use of their wireless internet connection. Imagine, not having to wait for a computer in an hot and humid internet café, or having to pay big bucks just to search for your next place to sleep. All you need is a mobile phone with which you can access wireless networks.
