Hi All,

Our experience with using the e-mail-to-SMS gateways provided by
AT&T/Cingular and T-Mobile:

AT&T: Messages come through with very little delay (even during alert
T-Mobile: 10-15 messages/hour are allowed through...then T-Mobile
refuses the IP for about an  hour.

Assuming, for the moment, that there's a cell signal available in 
your data center... Not always the case, unfortunately.
