T-Mobile and Verizon Are Basically Tied in Network Speeds and So-Called 'Availability'

Verizon is fighting back against T-Mobile's recent attempts to steal the network spotlight as the so-called "Un-carrier," according to the results of OpenSignal's latest State of Mobile Networks report published today.


Verizon regained a statistical tie with T-Mobile in overall network speeds, with an average download speed of 14.63 Mbps versus 14.7 Mbps for T-Mobile, according to OpenSignal. The metric factors in combined 3G and LTE speeds, in addition to the availability of each network technology, which can affect overall speeds.

Meanwhile, T-Mobile came within 2 percentage points of Verizon's lead in nationwide 4G LTE availability, according to OpenSignal. The report found T-Mobile customers had an LTE connection available to them 86.6% of the time, up from 83.2% in August 2016, compared to Verizon's leading 88.2% availability.

It is important to note that OpenSignal's "availability" measurement does not reflect geographical or population-based coverage.

OpenSignal's 'Availability' measures the proportion of time users have network access. By continually measuring whether users have a connection or not we are able to extend our assessment of networks to account for what happens when users are indoors and when they are moving around. We build up a holistic, user-centric measurmement of networks that expresses how users experience them.

The two carriers won or shared every award in every category of the report, leaving AT&T and Sprint with zero accolades.


Verizon still appears to have the faster network in a number of metro areas, including Chicago, Houston, Los Angeles, New York, and San Francisco.

Verizon ranked highest in speed in 14 of the 36 cities we analyzed, compared to four cities for T-Mobile and one for AT&T, but in seven other metro areas the speed contest between Verizon and T-Mobile resulted in a statistical tie. In three other cities we recorded a draw between AT&T and either Verizon or T-Mobile, while in the remaining markets, we saw ties between three or more operators.

Verizon had the lowest average LTE latency, the delay data experiences as it travels between points in the network, at 59.84 ms, compared to 61.28 ms for Sprint, 61.56 ms for T-Mobile, and 65.62 ms for AT&T. T-Mobile had the lowest average 3G latency at 115.76ms, according to OpenSignal.

OpenSignal said it parsed 4.6 billion measurements collected by 169,683 smartphone users in the fourth quarter of 2016 to gauge the 3G and 4G performance of the "Big Four" networks in the United States: AT&T, Sprint, T-Mobile, and Verizon.
