Re: coverage Tiger72, too bad they don't make any difference in the color to show whether it's 3G or 4G since they use different towers. Using the OpenSignal app I found the reason I can't get any data on my Samsung Exhibit 4G phone that won't work on 3G is because there are no 4G towers near me. The only ones in the Phoenix, Mesa or Scottsdale area seem to be located next to T-Mobile stores. There are 6-7 2G and 3G towers around but the nearest 4G tower is about 2 miles away so the signal is too weak to pick up unless I drive over to the mall but I don't hang out at T-Mobile stores that often.
