Greetings EdgarsAkmenkalns,
Thanks for visiting the Apple Support Communities! I understand you're unable to turn on Call Waiting with your iPhone.
Nice job with the troubleshooting steps you've taken. If your carrier confirmed the feature is provisioned for your line of service, then I suggest checking for a carrier settings update, and reaching out to Apple Support if the issue persists: Update your carrier settings on your iPhone or iPad - Apple Support
You can reach Apple Support here: Get Support
Cheers.
