T-Mobile vows to continue saying its LTE network is faster than Verizon’s
July 11, 2025
T-Mobilecame under fire last week from telecoms watchdog the National Advertising Division (NAD) for claiming it had the country’s fastest LTE network. T-Mobile had made the assertion in its advertising campaigns based on data from crowd-sourced network statistics groupsOoklaandOpenSignal, which verified T-Mobile’s position at the top.
However,Verizoncried foul, reasoning that the time from which the data had been sampled had unfairly put the results in T-Mobile’s favor. These samples reportedly arrived from the month following Verizon’s introduction of itsUnlimited Data plan, and Verizon suggested that its users would have been less familiar with the data throttling which is placed on those who exceed the fair use restrictions of such plans. Therefore, this may have resulted in more throttled users on Verizon’s network conducting speed tests than throttled users on T-Mobile’s network during that period.
This notion was upheld, and NAD recommended that T-Mobile cease using such advertising messages — something which T-Mobile initially agreed to. Now, it has changed its mind.
“NAD ruled that the one month of crowdsourced data we submitted (when Verizon launched their unlimited plan) could not be used,” wrote T-Mobile in a statement (viaFortune). “NAD previously recognized third-party crowd-sourced data as a way to look at network performance, so we looked at the latest results, and verified what we already knew! T-Mobile is still the fastest LTE network and we’ll continue to let consumers know that!”
