I upgraded to a new data package and downloaded an e sim yesterday. I now cannot make calls on my iPhone 16 but can receive them. What do I need to do please?

You say you upgraded to a new data package.
It wasn't a Data SIM by any chance?

Sometimes, simply rebooting your phone can fix issues.
Also, if you have a plastic sim in your phone too, remove it to allow the esim to fully activate.
