Availability: My thoughts on the unverified claims
The author's research assumes the user has "free minutes" already purchased which he/she can use for data at little or no extra expense. A mobile connection dedicated to a data application would not have a "bucket of minutes". Regular short bursts of data (a KB or two) would be extremely expensive once rounded up to the minimum 1 minute rate. The difference could be $0.50 on CSD compared to $0.01 on GPRS for each 1KB transfer. Hence original research shouldn't really be on Wikipedia, despite being interesting. In sure facts can be extracted from the section.k —Preceding unsigned comment added by 203.152.115.183 (talk) 21:48, 20 September 2007 (UTC)

There is confusion in the mobile support community about this, it would be good to get clarity. T-Mobile recently informed me that CSD in the USA is unavailable and has been for more than a year. Telstra in Australia has given a 2 year advanced warning of switching it off - some info at www.telstra.com.au/csdexit.

CSD is available in the US from AT&T. However, it is only available to selected business & government customers and is not available for consumer subscribers. Schnell (talk) 05:11, 15 December 2010 (UTC)
