Been a bitter sweet few days with my 6+. Love the phone but I have had some concerning issues with my wireless coverage ever since I got it, and have spent many hours on the phone with tech support trying to figure out what is going on. Before I get into what's going on let me preface with the fact that I live in a area with pristine lte coverage. My note 3 would never dip below 4-5 bars of lte, and the art tower is around 700 feet from my house. I have 2 main issues the first is so bad I may need to return my phone. I am not receiving 10-20% of my text and mms messages. I can go on my gf's phone and compare texts sent. I did not receive many of them. She is on android and on AT&T. I had a huge issue at work today when I was waiting for hours to hear back from our engineer. I called and he had texted me 4 times on his sprint android phone. The second issue is that I sometimes get dropped from lte, and then when it logs in I get no route. The phone shows bars but no data is able to be transmitted. The only way to fix this is going in and out of airplane mode over and over until I finally am able to use data. AT&T has been polite but useless. I drove down and swapped out the SIM card, and I still get weird lte issues. I unfortunately have no idea how many texts I am missing. Since it is sporadic they eventually just hung up on me. Could this be a issue with the phone itself? I never had any issues with my note 3. The only thing that has changed is the phone, SIM card, and I went to a volte unlimited plan. Is it worth making a genius appointment? I absolutely need to get my texts for work, and today could have potentially cost a lot of money had I not decided to call. Any advice is greatly appreciated.
