Not receiving code activation text message (Twitter, QuickBooks...)




    For some time I was not able to secure my Twitter account and other online services with a two factor authentication security. This means I wanted to have :

    1) user & password

    2) code sent to my phone by text message


    Today I invested again some time and reached out to the Business Team via chat. Angie was awesome and after checking several system settings on T-Mobile end, she found out that all short numbers were blocked on my account. Twitter typically sends from "40 404".


    Once this blocking was deactivated, 30 seconds after I tried again and could successfully activate my T-Mobile number for Twitter :-)


    So I wanted to make sure to share this great news as I have been searching a while.
