New OpenSignal report crowns T-Mobile as the best overall network. Despite the cheesy Verizon commercials you have been seeing on TV lately, in which a bad comedian tries too hard to tell everyone that Verizon is the best mobile network, nothing could be further from the truth. In fact, T-Mobile is head and shoulders above the other networks in Download speed, both at 4G and 3G, and in availability of 4G service. Marry that to the fact that I have more devices online, and am paying several hundred dollars a month less that I paid Verizon, and without garbage over charges, and the switch to T-Mobile is the best thing I have done in a long time. I still have a bad taste in my mouth from the greedy Verizon network, and the total lack of care I received as a Verizon customer. And, they hit me with an $1,100 termination fee on my way out the door. If you haven't switched, you should consider it.
