New Samsung phone recognises old SIM phone number

[PeterBar_761083]

Samsung s24 ultra is recognising a phone number that was originally assigned to the SIM.

I ported across my new number to this SIM when using my previous phone but today I pop this SIM into the new s24 phone and it is detecting the old number. 

I have placed a friend's tesco SIM in and the phone detected that one no problem. 

I have placed a friend's smarty SIM in also and again it detects the number assigned to the SIM not the ported one.

If you ported your number to Smarty then it is recommended to turn off any messaging services & then reset the phone’s network settings.
