Consumers
take a number of factors into account when buying a mobile
phone. The ability to make a successful call is one such factor.
The four mobile network operators - BT Cellnet, One2One, Orange
and Vodafone - have worked with OFTEL and consumer groups
to produce survey information on call success rates(1).

on the links below to find out the results of individual operators’
call success rate surveys on their own digital networks on
a regional and national basis.
The quoted
performance figures are not directly comparable due to the
tolerances inherent in the survey specification. The operators
together with OFTEL and consumer groups, are currently working
to further improve the methodology, comparability, and accuracy
of the survey approach used.

Reference to "call success rates" refers to the
test equipment’s ability to set up and hold a call for
two minutes. This measure does not give a figure for the audio
quality of the call.
