Uh I understand cause and effect. And I never said tmobile coverage is better than AT&T or Verizon. What I'm saying is that tmobiles aggressive moves has caused the other carriers to react and change their services. There's no way IMO that next, edge, framily, mobile value share, etc would be here if tmobile didn't successfully introduce uncarrier.
I agree to disagree with you, because at least with verizon you have no proof of a direct correlation.
