According to the statistics of a recent consumer survey conducted by ChangeWave Research, AT&T – the Apple iPhone’s exclusive US carrier – holds the last spot among the four leading carriers of the country, in terms customer satisfaction and percentage of dropped calls.

Going by the latest ChangeWave findings related to customer satisfaction among the four main US carriers – Verizon, T-Mobile, AT&T, and Sprint -, only about 25 percent of the AT&T customers are reportedly “very satisfied” with their service; vis-à-vis the nearly 50 percent customers of Verizon, which is the biggest mobile provider in the country.

Conversely too, in terms of unsatisfied customers’ figures, almost one-quarter of AT&T customers reported that they are unsatisfied with AT&T service; as against barely six percent of Verizon customers who reported being with Verizon service.

Furthermore, as per the ChangeWave survey, the incidence of dropped calls was also the highest for AT&T customers, despite the carrier’s continuing attempts to enhance its network.

The 4.5 percent average dropped-call rate reported by the AT&T customers was nearly three-fold higher than the rate reported by Verizon customers. Incidentally, the average overall dropped-call rate for all carriers was 2.8 percent; with AT&T being the only carrier to be reporting an increasing rate, as against the other carriers that have shown a notable decline in their dropped-call percentages.
