johng Posted June 11, 2009 Report Share Posted June 11, 2009 There is a good explanation of CDMA Cellular technology at wikipedia... http://en.wikipedia.org/wiki/CDMA2000 CDMA is typically found in the USA and Canada. NRG CDMA iPacks typically use 1XRTT connection technology. Most CDMA carriers no longer support "circuit switched" connections, although the NRG iPacks still do (just in case).
