Short Code Messages
My phone is not receiving (and never has received) what I think are called "short code messages" (such as...a bank may text me a short code of about six digits that I can then regurgitate back to them to prove the I am myself...but these codes NEVER arrive, from any entity who tries to send one). A bank told me the service provider (AT&T) has likely disabled "short codes" for my account...but getting through to speak to someone at AT&T is a many-hours-wait prospect that always ends in failure, and the online tech support capability only runs me through the smplest most obvious things I'd naturally have already tried (like power-cycling the phone, disabling/enabling messaging, etc). Is there a way I can enable such short code messages myself? I already have SMS and MMS protocols enabled.
Thanks in advance.
