experiencing difficulties accessing my Facebook account due to an issue with two-factor authentication (2FA)

I am experiencing difficulties accessing my Facebook account due to an issue with two-factor authentication (2FA). When attempting to access my account settings, I am prompted to enter a verification code sent via SMS. However, I am not receiving any SMS codes at my registered phone number. I have already verified with my mobile carrier that there are no issues on their end, and they have confirmed that the problem lies with Facebook's SMS delivery system. Please help me resolve this issue so I can regain full access to my account. I am happy to provide any additional information needed to verify my identity or troubleshoot the problem. Looking forward to your response.
