For the past few weeks we have been getting alot of "all ciruits are busy" messages.This happens when were on reg towers or over wifi.I called T-mobile and they said that there is too much traffic on the network in our area.I know it's true because my BB displays the word congestion!My question is since T-mobile just started service here last year should the towers already be overloaded and why?They said "they could do nothing about it"sorry!I hope this clears up soon!!
