You would be correct, because it HASN'T changed in ALL of the years I have had the plan or the carrier.  Any change, like this one, is easily visible.  With your question, then why do they send out an automated text telling you to view your bill if it is just going to come in the mail or via email?  Why send me a text to verify that I have submitted a payment?  Or why send an email that my bill is late, especially when one knows that they haven't paid it?  Yes....why send out ALL of these reminders that one is completely aware of?  All I am saying is there could be another form of automated communication when changes are made!!!  Be consistent!!
