Why is Enable SMS option missing on my iPhone 14 Pro?

iPhone 14 Pro doesn’t give me the enable mms or sms option. I have looked everywhere and cannot find it. When I place my SIM card in a different phone, it can send messages. What do I do?

I have been trying to send a normal sms message using my iPhone 14 Pro but the enable mms pop up keeps showing up.

I have looked for the button to enable the mms or sms but it doesn’t exist.

my phone carrier does do sms services because when I put the sim in another phone I can use it to send local texts. Please help.
