If you have a never registered, not expired SIM for a carrier, the carrier can register it to an account given the IMSI. You can also do this with eSIM without needing a physical SIM.
So, step 1, convince the carrier representative. Step 2, give the the IMSI. Step 3, put the sim in your phone and receive SMS.
If you do step 1 in a physical store, the representative will probably give you a new sim from their stack even.
