Please notice:
When measuring speed via UMTS and HSDPA, larger amounts of data are transferred, which consumes some data volume. We recommend the use of a data flat rate if you want to run more than 3 tests per day.
However, the selected speed has no influence on the measurement and only serves as a comparison option after the speed test has been completed.

How the UMTS speed test works

Very many factors play a role in the speed test for mobile data connections, which could affect the measurement. The signal strength of your end device (smartphone, tablet or notebook) is crucial for the maximum achievable data rate. If the signal quality is poor, the connection speed can drop massively, so you should test the measurement on different weekdays with different weather conditions in order to calculate an average value yourself.
In addition, it can happen that a large number of users are surfing the Internet via their smartphone at the same time and the corresponding transmission mast is at full capacity. All wireless users have to accept losses in this case. Furthermore, you should make sure that all other programs or apps are closed during the UMTS speed test. that could possibly perform updates in the background and thus influence the test.

Why UMTS? I have DSL!

In many regions of Germany, there is unfortunately still the problem that the cables necessary for DSL, or cable Internet have not been laid, or are simply too weak to provide a stable and fast Internet connection.

Often, it is simply not worth it from the providers' financial point of view to lay a reasonable cable for "a few thousand villagers". Thus, some providers offer corresponding UMTS (also HSDPA & HSUPA) rates to supply these users with Internet. Until some time ago, UMTS, later HSDPA was the standard in terms of "mobile data transmission".

Currently, providers are switching more and more to "LTE", so we now also offer a LTE speed test with especially large data packages.
