I am incredibly late on updating phones that I use as well as updating to this forum, but here's my experience with updating the phones profile: When I go to work, in my carrier's network, I somehow magically go into roaming status. The complicated part, is that I'm the only one at my work that uses the Sprint network. It doesn't happen as soon as I walk through the door so much as soon as I reach the back of the building...my problem is that when I go out the door at the end of my shift, about five minutes, I go back to normal non roaming status. my work shares the building with three other businesses. when I enter the others, I don't go into roaming, and I can be in the back of their building and even behind the building and outside and still not roaming; only when i'm in my work's building. I call my carrier, my carrier advises to update the profile, and today, we'll see if that worked. Afterward, I'll come back, and update once again.
