Not receiving verification codes via text

[Textfailure]

I'm not receiving text messages from websites (including O2) that require a verification code to be entered. My mobile number has changed, the websites have the correct number (including O2), in my text message history I can see previous, recent, text messages from websites that have arrived. I have upgraded the software on the phone. I have switched it off and on. Nothing. Why?

I don't use social media.

Just like to speak to someone, I know it's old fashioned.

Well, O2 will never call you back, so call them again, @Textfailure - be persistent.

Had enough for now.

Will try again later when I've calmed down

Sounds like a plan - or pop down to an O2 Shop if one is nearby, and take photo ID with you:
