I had at&t for over 16 years. I figured all cell carriers are pretty much the same so I just never made the switch. This last year was the last straw, I'm embarrassed I waited so long. Challenges/regrets: 1.) they're prices are at least double of all the competitor providers. Long term loyalty meant nothing when negotiating a reasonable plan. 2.) the customer service was a never ending headache; I constantly had additional charges for things that I had to dispute yet the resolutions given by customer service never seemed to match my bill, meaning more hours of calls, hold times, and reexplaining my concerns to god awful customer service reps. Never ending. 3.) I brought my fiancé to my plan. She traded in her 6S iPhone (brand new) because we were told we'd receive a buy out. They took the phone, gave us the steps to follow, we did everything at&t told us to do and in the end we got NOTHING for that phone. Nothing short of stealing my fiancé's phone and then charging is an arm and a leg for service. Loss of over $600. We tried to get the phone back and after weeks of effort they said there's nothing they can do and they no longer have our phone 4.) when I finally moved to another carrier I reduced my bill by 2/3rds and I have an additional line! (Sprint) I discovered, after weeks of calls and effort, my paid off iphoneX that was finally was unlocked but unlocking doesn't matter because the phone can only be used w at&t service. So what's the point of unlocking? I paid over $1,000 for that phone! What a scam. In the end I feel like the foolish one. It was an abusive relationship and I should have left them years ago. Don't make the same mistake I did. DON'T DO IT!
