Which network does PremiumSIM use? Network coverage and quality

PremiumSim offers cheap tariffs, but which network does the provider use and what about coverage and quality? We explain the details in this CHIP practical tip.

PremiumSim: Telefonica subsidiary uses O2 network

• PremiumSim is a subsidiary of the Telefonica company and uses the in-house O2 network.
• In the CHIP network test 2014, O2 and Eplus only took third place and were beaten by Telekom and Vodafone.
• Although the provider does not offer a high-speed network like Deutsche Telekom, you will still have no problems making calls.
• The 3G network is also well developed in urban areas. In some cities you still have to do without LTE.
• O2 is particularly difficult in rural areas: LTE availability is usually poor. Surfing pleasure will not arise here.
