Can't call out with new phone

My eldest got a new phone (second hand Samsung Galaxy S21) and since inserting the SIM card, he can no longer call out or go on the internet (Wi-Fi works fine).

Weirdly, the SIM card phone number displays a different number to the one that he had, as if it changed with the new phone.

There is definitely coverage as I use SMARTY as well and my phone is fine.

Any help would be appreciated.

    Leonard_2705678​ Any chance that it is somehow locked to the previous network that it was used on?

    Does his Account show the correct number and an active Smarty plan?

    Has he tried the 'turn it off and then back on' thing to try and force phone to connect to Smarty?

    Is sim definitely correctly inserted in phone?

      The old phone was using the same SIM card and worked fine; issues only happened when transferring to the new one.  We tried taking the SIM out and putting it back it with no luck as well as turning it off and on again, still no signal.
