Does the Qin F21 Pro (global) work on Telekom?

Q: Does the Qin F21 Pro (global) work on Telekom?

Works with caveats. Calls and texts can fall back to 2G. Telekom plans to switch 2G off completely by 30 June 2028. We haven't found confirmation that 4G Calling works on Telekom. 4G data should work (shared bands: 1, 3, 7, 8, 20).

Yes, for now.

Fine for now. The catch is how calls get through: if they ride on 2G or 3G, they stop when Telekom switches that off.

We worked this out from the phone's published bands and Telekom's own published network facts (see How we check). Nobody has confirmed it for this exact pairing yet.

Telekom (Germany)

3G: Switched off in 2021
2G: On until 30 June 2028, when Telekom plans to switch it off completely

Qin F21 Pro (global)

2G: GSM 850 / 900 / 1800 / 1900
3G: Not published or not checked yet
4G bands: FDD 1, 2, 3, 5, 7, 8, 17, 20, 28; TDD 34, 38–41
4G Calling: not by default – VoLTE isn't enabled out of the box; a jtechforums guide enables it with root. UK owners report it working on giffgaff/O2 and Vodafone (calls over 2G).

The same applies to networks that run on Telekom: congstar. Smaller networks sometimes handle 4G Calling differently, so check with them too.

Vodafone Works with caveats
O2 (Telefónica) Works with caveats
1&1 Works with caveats
