MY phone not able getting network signal .my phone very slow performance

The No Signal could be a problem with your carrier, have you been told of any outages in your area? Do you suddenly get service in another area?

Please take a look at If you see No Service or Searching on your iPhone or iPad - Apple Support for further assistance.

My iPhone 12 mini is extremely slow since my last update. What’s going on?

Sorry I put my question in the wrong spot
