Yes, T-Mobile roams on AT&T but only in a very few places and almost never in markets where they both offer service. T-Mobile cannot roam on US Cellular since they use incompatable technologies.
yea TMOB on roams in some places where ATT lets them. otherwise you will just be without signal where usually an ATT person would have signal. Usually in Rural areas.
