Not receiving any automated texts

I just switched to Xfinity Mobile from T-mobile, i realize im not receiving ANY automated texts.

(Automated texts as in, when you try to register something online, and they ask you to verify my phone number, so they'd send me a text. I am not receiving texts from anywhere, Google/Bank/Linkedin/Tinder...)

so what should I do? It looks like xfinity mobile is unusable basically!?
