Our office is horrible....however, all my other phones worked well enough. Calls went through, calls came in...with my S3 I can only count on not dropping a call in there if i stay in one specific place. Most incoming calls won't even ring, goes straight to vm. Out in the field where signal is strong(4g) everything is fine but many times while in 3g with 1-2 bars i will drop calls and even get "network unavailable" with bars showing.
If ignorance is bliss, why aren't there more happy people out there..........?
