Is the subscription really unlimited?Yes, the data volume is unlimited
Will my speed ever be throttled?Generally no, however we reserve the right to temporarily lower network speeds if malicious usage is suspected. However, excessive use can lead to capacity problems, which has a direct impact on other mobile subscribers. We therefore ask you to use the mobile internet within a reasonable range.In extreme cases (more than 97% and 99.89% of all customers) we reserve the right to temporarily lower the priority of data traffic. This means that speed will be reduced in places and at times of day when the mobile network is congested. This is generally only noticeable during data-intensive activities. In antenna cells that are not overloaded, the deprioritization does not affect the speed
