Why do I see the message 'Loading...' without anything happening?

With weak mobile phone signal, it may happen that the data connection is lost and thus pages cannot be loaded. If a new page is not displayed after 30 seconds, click the original link again, which will restart the transfer and possibly establish a new data connection. If this does not help, restart either the web browser on the mobile phone or the mobile phone itself. Go to the options and define that portatour® shall keep the internet connection (see section Internet connection) – this reduces the probability of failing connections. In addition, we recommend to activate the offline mode (see section Offline mode).
