Remind me, please. Are we still supposed to do *228 on our Razr MAXX? I'm starting to have issues with my texts not coming in when they were sent (sometimes delayed by 6-8 hours) so I thought maybe I need to update my roaming. But it seems like there's something we used to do with our older model smart phones that we're not supposed to do with the newer ones. I just don't remember what I is. TIA!
