Roaming disconnecting in Detroit (AT&T)

[JAG_ON]

In Detroit, I got roaming connected with AT&T, it works for a few minutes and then it disconnects. I try everything and cannot connect back. Little Caesars Arena at the moment.

What may be happening is that the phone is "hunting" for the best connection. Once you're on AT&T, go into the phone's settings and choose AT&T as your network instead of "auto".  Once you're done roaming, switch back to Auto, or Rogers.
