I am having an unusual problem, I have tried everything to fix it and nothing has worked. When I try and call this one specific phone number my phone will display "number not valid". I have tried the sim in a different phone and it works, so it's not the sim card. I have tried a new sim in the phone itself and it still doesn't work. I can call other numbers from the Samsung and they work fine. I have tried altering the network settings specific for my network and that doesn't work either. I have tried calling from a different phone and it works. It is simply an issue that occurs when I try and call this specific number from my Samsung A42 5G, so I believe there is an issue with the device, I am very puzzled. I haven't blocked the number either and I don't have any other number blockers installed on the phone. Any suggestions?

Thank you for the response. I have tried everything I can think of including changing the format of the number and that hasn't helped either. I have factory reset the phone and the problem is fixed for a time but then occurs again. The same happens when I restart the phone, the issue is fixed then returns when the phone has been on for a time. It's very puzzling. I have contacted my network to see if it is something on their end but at this point it may be a case of just switching networks to avoid this issue, there simply doesn't seem to be a fix.
