Yeah, they need to. T-Mobile already has some active Band 12 700 MHz sites here in Fort Lauderdale. I was able to connect to two yesterday. Sprint tower near my home hasn't still not being updated with Network Vision only hosting Clear's Band 41 which is not strong enough to get to my home and the 3G signal has been horrible ever since mid 2013. Hoping the 800 MHz Band 26 deployment will allow me to pick up LTE from another site.
