congstar runs on Telekom's network, so we show Telekom's results unless we have a congstar-specific source. Telekom's 2G: On until 30 June 2028, when Telekom plans to switch it off completely. 3G: Switched off in 2021.

Smaller networks sometimes treat 4G Calling differently from the big network they use (for example, Light lists giffgaff as compatible with the Light Phone II but not O2). If in doubt, ask them before you switch.
