Can’t make calls

[Luce135]

I have a new iPhone 14 but can’t make or receive calls.

This happened with my previous iPhone 13.

Have tried everything including replacing with different Sims and installing an Esim.

Have reset network settings and turned off phone. 
Nothing works!

If it's happened with 2 phones and multiple SIM cards then it is either a network fault or something wrong with your account
