I can’t call from my new phone

Did you transfer the Sim card too ?

I am assuming that you followed the steps to transfer your data to your new iPhone, using these support articles:

• Transfer data from your previous iOS or iPadOS device to your new iPhone, iPad, or iPod touch - Apple Support
• Set up your iPhone, iPad, or iPod touch - Apple Support

... and it cannot make calls, then I would start with this article:

• If you can't make or receive calls on your iPhone - Apple Support

You may also need to contact your cellular voice provider for additional assistance with this matter.
