I have unlimited text and data for my Droid 2. I receive texts fine but not from Google Calendar. Google suggests the following: "Please contact your mobile provider to verify that your mobile provider is not blocking short codes from Google (48368) "
My wife has the same problem. She does not receive text calendar notifications from Google.
Any ideas beyond the suggestion above?
My understanding is that short codes 46645 and 48368 are both for Google so your routing is ok. I would recommend working with one of the mods or calling Customer Care to open a ticket.
