Hello tweeter93,
It sounds like you're noticing an untrusted app message when you make a phone call. Are you using the Phone app to make the call or a different calling app?
If you're using the Phone app to make the call, be sure to have installed any available software updates: Update your iPhone, iPad, or iPod touch - Apple Support
Also, check for a carrier settings update: Manually update your carrier settings on your iPhone or iPad - Apple Support
If you're using a different calling app, please let us know.
Take care.
