It could be the phone or a carrier issue.

The iPhone 7 had issues in the past with cellular connectivity. Apple was aware of it and for a while would fix the issue free of charge but that program has ended.

Take it to a Genius Bar and have it diagnosed. If they find nothing wrong with it, then contact your cellular carrier for help.

Make an appointment at the Genius Bar to have it diagnosed.
