I´ve been with PremiumSim for more than 6 years. PremiumSim belongs to Drillish Online (who also owns other brands like WinSim, Sim.de, Handyvertrag, and many more...).Last month I changed from PremiumSim to Handyvertrag (within the same company) just because the second one offered me better conditions. Well... last month with PremiumSim they reduced the speed of my internet and remove completely network coverage while on the Underground. I guess, just because it was my last contact month with PremiumSim, they decided I was no longer a worthy customer. German laws doesn´t protect customers so... to who am I complaining? Also, on my last invoice they charged me 17€ in concept of "Markenwechsel". I´ve done researches and happens to be an extra fee they charge just if you swicht from brand within Drillisch. Funny, they don´t announce it anywhere, but they happily charge the final consumer. I guess is a "reward" for themselves for loosing a client.Yesterday I started using my new Sim Card from Handyvertrag, and... SURPRISE, full speed, full coverage for calls and surfing while travelling on the underground.It´s sad. I thought Drillish was a great company, now I regret to have a new contract with them. Eventually, I will change.
