Hello Mac Rumors community! Long time lurker here : ) I have AT&T here in Hoboken, NJ just across the river from Manhattan. Since I've switched to the iOS 11 beta on my 7 Plus and especially with the latest update, I've been experencing extremely slow LTE speeds. I guess you can't even call them LTE speeds since my phone is basically a brick at this point until I connect to wi-fi. I can't even run speed tests on the network because it's so slow. Furthermore, while i've never experienced great reception while actually using the phone as a phone with AT&T, with this latest beta update it's unusable at the moment. Call drops 90% of the time or I have connections where I can hear the caller but they can't hear me. Has anybody else been having similar experience with AT&T or for that matter any of the other carriers with this latest beta update? I read the article from a few days ago about AT&T and Verizon users experiencing slower LTE performance this year (which I've noticed even before the beta installation) but what my phone is doing now is absurd. I'm chalking it up to the beta at this point and hopefully with the next update it improves but when the new iPhone comes out i'm seriously considering finally making the switch to T-Mobile after over 10 years with Cingular/AT&T. Thanks in advance for your thoughts!
