Congstar uses the Telekom network, the best mobile network available in Germany. However, there are a few GPS trackers that do not work with the D-network. An example of this would be the TK-102 from INCUTEX.

Conclusion: SIM card from CONGSTAR

CONGSTAR’s prepaid tariff comes second in our comparison. A low basic price, low SMS costs for Germany and the EU, high customer satisfaction and the best available network are strong, but the decisive points have to be deducted for problems with compatibility and relatively expensive mobile data.
Our conclusion: The SIM card from CONGSTAR is a good tariff and is convincing on most levels. However, if you want to be sure that the GPS tracker works perfectly, we recommend the test winner.


As mentioned above, there are compatibility problems with the CONGSTAR SIM card. These are generally SIM cards labeled c/we. However, the inscription is only revealed once the card has been received, which is why the problem cannot be prevented in advance. After a few months, error messages appear and the SIM card is not recognized by the tracker or cell phones. CONGSTAR should be contacted at this point. The provider offers an exchange free of charge, but all in all it is an unnecessary and annoying expense.
