Verification codes not working

[00761532]

I am having an issue with receiving the WhatsApp verification codes, I have exhausted all other avenues such as removing iCloud, uninstalling the app etc, increasing spend limit and turning off wifi calling. WhatsApp have suggested I speak to O2. I ported my number from another service provider and have read on here this can cause issues? Can anyone help
