Does the Cat B35 work on KPN?

Last checked 23 Oct 20265 sourcesWorked out from published specs

Mostly, with a catch.

Works with caveats

Calls and texts can fall back to 2G. KPN switches 2G off for good on 1 December 2027. We haven't found confirmation that 4G Calling works on KPN. 4G data should work (shared bands: 1, 3, 7, 20).

It works today, but calls on the Cat B35 rely on a part of KPN's network with a switch-off on the way. Check the dates below before you commit for years.

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

KPN (Netherlands)

  • 3G: Switched off (31 March 2022)
  • 2G: On until 1 December 2027 (KPN started moving customers who don't need it off 2G in March 2026)

Cat B35

  • 2G: GSM 850 / 900 / 1800 / 1900
  • 3G: Not published or not checked yet
  • 4G bands: 1, 3, 7, 8, 20
  • 4G Calling: unknown – No network or maker VoLTE confirmation found.

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