In areas where T-Mobile has a network, you may not be allowed to roam
onto Cingular, even if you're in a location where you can a Cingular
signal, but no T-Mobile signal. This is the case where I live,
Cingular's coverage on AT&T's old 850 MHz network is fine in my
neighborhood, but T-Mobile has no coverage, and T-Mobile users can't
roam onto Cingular. T-Mobile has been trying to get permission for a
1900 MHz site for years (first it was Cingular trying to get permission,
then when T-Mobile took over the 1900 MHz network, it became T-Mobile's
battle.

It's a never ending issue, since 1900 MHz doesn't have the range or the
penetration of 850 MHz. This is why T-Mobile tries to make up for their
network by offering more peak minutes for the money.
