is there anyone who can help me

I don’t think you can send SMS with a fritzbox through HA.

But there are a few other options to send SMS:
Use a GSM modem: SMS notifications via GSM-modem - Home Assistant
Use a service: Twilio SMS - Home Assistant
There are also services that you can use through mail (and the SMTP integration)
You might be able to use Tasker for that (if you have an Android phone)
