No. In the end I changed my camera.

No, not any more! 9 days before I ordered it apparently the service was cancelled.
see reddit.com:
Whatsapp stopped working nokia 6300 4G : r/KaiOS (reddit.com)
have therefore sent it back

No. Just received it in August 2024 and tried to set it up. Whatsapp app crashes. They removed support in July of this year supposedly.

Yes, but only messages and voice calls.

Is there a push-button phone on which Whatsup works?

Thank you! Do you know of a push-button phone on which Whatsup works?

No

No. Since June 2024 WhatsApp is not supported anymore on this phone. I had to send it back one week ago.

For people that activated WhatsApp on this phone before June, it’ll be working until February 2025.
