As with other test reports*, Stiftung Warentest has focused on different areas. Vodafone, Telekom and O2 mobile networks, on the other hand, were screened, with a weight of 30 percent for phone and 70 percent for internet. Load times of many websites were checked as well as download and upload speeds.
Telephony was about the percentage of calls made successfully as well as call setup time and sound quality for normal calls, but also for Whatsapp calls. Stiftung Warentest is measured in 14 major cities such as Frankfurt, Freiburg, Hamburg and Berlin. Outside the cities, car trips were also screened for the best mobile network.
The conclusion of Stiftung Warentest: Almost all three providers tested are good. And most importantly, after the 2017 test, everyone made progress.
Of course, there are small differences between mobile service providers, with Telekom taking the first place in the end, slightly ahead of Vodafone. Telefónica/O2 is the “good third” but it catches up to it in a big way.
- 1st place: Communication
- Second place: Vodafone
- Platz 3: Telefonica / O2
Stiftung Warentest: 1 & 1 newcomer not yet ready for testing
Certainly, with 1&1 there is a fourth provider. The newcomer has not yet been included in the Stiftung Warentest investigation. Reason: 1&1 is currently expanding its mobile network. Currently customers are still supplied via the O2 network. The new provider may be part of the next test report* when WLAN is launched across the board.
Speaking of all over the country: In the last test, the O2 had its problems, especially in the cities. In addition, the Spanish provider managed to catch up. However, Stiftung Warentest* testifies that mobile service providers still have room for improvement. However, one dreams of such a balanced result when scrutinizing cosmetics such as pressed powder *or even a pasta comparison*.
Comparing mobile phone connections: Germany has recently weakened internationally
Germany still performs poorly in comparison with the European Union. According to the test results on connect.de, Germany ranks only 16 out of 28. The top three places belong to the Netherlands, North Macedonia and Austria. However, the 2020 test also said that it should not be seen as a “complete network test”, but that it could certainly be a trend.
Two years ago, the best mobile operator was Telia from Sweden, followed by Vodafone Netherlands and Swisscom (Switzerland). German network operators are ending up in the back. Telekom is still 33rd out of 98 providers, Vodafone is 44th and O2 is 77th. By the way: According to the Federal Network Agency, Vodafone had the largest number of users in the network last year. * Like RUHR24, HEIDELBERG24 is part of the IPPEN.MEDIA editorial network.
