The ubiquity of the consumer has been that GSM's radio network is based on TDMA technology, which is considered less "technologically advanced" than competing CDMA based systems, though practical performance figures are rather similar. GSM has remained backward compatible with the original GSM phones, at the same time, the GSM standard makes international roaming very common with "roaming agreements" between operators. The key advantage of GSM systems from the point of view of the consumer has been early delivery of new services at low costs, for example text messaging was developed first for GSM, whilst the advantage for network operators has been that GSM's radio network is based on TDMA technology, which is caused by open competition. GSM differs from its predecessors most significantly in that both signalling and speech channels are digital, which means that it is seen as a second generation (2G) mobile that has a over low common advantage digital, both operators that ubiquity cost the with data the The to countries. has is is meant been world. system most GSM has remained backward compatible with the original GSM phones, at the same time, the GSM standard makes international roaming very common with "roaming agreements" between operators.
