Which Fair Policy is applied for the unlimited devices?

This service is based on a mobile connection and if you use it intensively you subtract bandwidth (and speed) to all other users connected to the same cell (antenna).
For this reason, all telephone operators apply "fair policy" rules and may suspend a sim that is continuously connected and uses a significantly higher volume of data than national averages, even in the case of "unlimited" data plans.
The operator we use (Wind-Tre) has the right to suspend a SIM if it is connected continuously for more than 3-4 consecutive days and has an average daily consumption of over 15-20 GB. There are many other factors that contribute to the possible suspension, first of all the global use of the cell, but the important thing is that if the sim is suspended by the operator, we must open a case and, generally, the reactivation takes place in 2-3 business days.

For this reason, to avoid long suspensions, we have decided to apply our own "fair policy" and suspend the data connection just before the operator can apply his own one, with the great advantage of being able, in this way, to reactivate the SIM autonomously and automatically. Our suspension may be applied if you have an average data usage greater than 18GB per day for more than 3 consecutive days, which is an exceptional usage for a mobile connection.

To better understand this value, please consider that 18GB let you watching movies as follows:
 - about 26 hours with video quality set to “standard” (720p) - average consumption of about 0.7 GB per hour;
 - about 9-6 hours with video quality set to “HD” (1024p) - average consumption of about 2-3 GB per hour.

In case of suspension, you will see "Internet not available" on your device until midnight. After midnight, the data connection is automatically re-enabled and you will be able to use your device again!
