The Internet quality improves greatly when the card is finally charged with credit. The first charge was very confusing. Neither the instructions from the mobile WLAN router still helped by the map, I have long experimented and researched before it worked. Top up online was not because the supplied number was not accepted as a valid telephone number. I finally got bought Vodafone credit at the grocery store, and so I could recharge the card online. First you need to go to the corresponding web page from router to establish these, this one has to get out of his usual power and take the connection with the router, although it still has no credit. Even with no money to get to the Vodafone page automatically when you try aufzufen a side (no matter what) on the Internet, and then you get (more than once day, 15 minutes free on the Internet, you should use it) to charge the credit. Or you can use the voucher for 24 hour access. Once charged it all by itself, no matter what device is connected. 15 minutes videogame plastered 100 of the 200 MB of the most inexpensive flat, but everything else, also U-Tube videos is quite economical. So you can take his own Wlan inexpensive holiday or weekend. Home as fast as my wifi.
