AT&T GSM 850 Blamed For Police Radio Outages In Oakland

This is when having a nation wide roaming deal would come in handy. I understand that only the GSM 850 band is shut off but it's California when every cell tower counts. But if they had roaming with T-Mobile and other GSM operators in that area they could use that to help that area from getting degraded to bad.

This of course is pure speculation going off the article.
