John Legere posted a picture with two phones, one on T-Mobile, and one on Verizon, directly comparing the speeds that each network was able to muster at the stadium. Needless to say, the comparison is in T-Mobile's favor, as it managed to score almost four times Verizon's result on the download side, and more than two times on the uplink.
T-Mobile didn't stop here, though, as it issued a chart comparing the average LTE speeds that all four major carriers were able to deliver in San Francisco around game time, and Verizon is lagging quite behind there, despite a $70 million investment to boost coverage in the area before the game. Big Magenta also had a 30-second spot during the game, dissing Verizon again, which you can see in the slideshow below.
Verizon, however, is quite nonplussed from all the trash talk, it seems, and issued a rebuttal ad, where a guy with a magenta beanie is still waiting for said T-Mobile ad to load, while his friends are getting impatient around him. Pass the popcorn, organic non-GMO if you have it.
