AT&T Mexico’s download speeds head south in OpenSignal’s new report

Telcel captured five of OpenSignal’s seven awards in our State of Mobile Networks report for Mexico — and it accomplished that feat with practically no movement in our metrics. With the exception of overall download speed, Telcel’s results stayed flat over the last six months, but its rival AT&T saw its download speed measurements drop considerably in our results, which allowed Telcel to dominate our awards chart.

Our analysis show that AT&T’s average 4G download speed fell 30% from 21.7 Mbps to 15.2 Mbps since our last Mexico report, and its average overall download fell by 4 Mbps to 12.3 Mbps. In the spring, AT&T introduced new prepaid unlimited 4G data plans under the Unefon brand that placed stiff restrictions on download speed, which may have had an indirect impact on AT&T’s speed results. While we didn’t include any Unefon measurements in our analysis of AT&T’s speeds, the operator’s postpaid and prepaid customers share the same LTE network. The success of these new unlimited plans may be increasing the average volume of data consumed per subscriber, which could cause speeds to drop for postpaid customers.

AT&T did, however, maintain its lead in our 4G availability category with an impressive score of 81.5%. AT&T remains the only Mexican operator to have surpassed the 80% mark in LTE availability. Despite a slight drop in its 3G download speed results, AT&T also held onto its lead in that category. But in all of our other metrics, Telcel is now the operator to beat.

Be sure to read the full national analysis as well as our breakdown of metrics in Mexico’s largest cities. If you’re a mobile subscriber in Mexico, we’d love to hear about your own experiences on AT&T, Movistar and Telcel’s networks. Tell us about them in the comments section below or on Twitter.
