So once again, I'm having problems with the data on my phone. I got an email from att saying they've made network upgrades in my area. I can tell. Places where I was getting 1 or 2 bars, I'm getting 4 and 5 now, but that's not the problem. In areas with good and bad coverage, sometimes I can't get data. Im between two places that are both in rural areas, but get decent coverage. One gets 5 bars like i stated before. I'm in the city for working and shopping, but I don't use my phone enough out there to see if this happens there too. Any clue what's wrong? I have a pic in one of the rural area with 4 or 5 bars and no data.
