Availability
The T-Mobile system is area/city specific. It works in Denver, Colorado, Savannah, Georgia, Washington, DC, and Miami, FL and Las Vegas into SoCal roaming onto Cingular. There is no service in Sarasota, Florida or anywhere in Texas. Fax services required a second number for an additional $10/mo.
The AT&T Mobility GSM EDGE network supports CSD in legacy Cingular and AT&T Wireless footprint areas. It is not generally available but can be provisioned for selected customers with specific needs requiring the service.
Currently in Australia, CSD is only available on Mobile Plans with Vodafone, Optus and Telstra, however Telstra is in the process of shutting down their CSD network as of the 4th May 2010.
In the UK CSD is available with all of the mobile networks but may require activation by the networks customer service team. CSD is commonly used in the UK for early smart metering deployments and as such there are no real plans to decommision or remove access to this part of the 2G network.

Famous quotes containing the word availability:
“Since ... six weeks ago, there has been no day in which I have not had letters and visits on the subject of my nomination for the Presidency.... I say very little. I have in no instance encouraged any one to work to that end.... I have said the whole talk about me is on the score of availability. Let availability do the work then.”
—Rutherford Birchard Hayes (1822–1893)
