For the last week or two, I have been experiencing unacceptably slow data performance on my TWO apple products: an iPhone5 and a 3rd generation iPad. Very slow performance of all apps that require a web connection, and frequent "connection to server has been lost" messages. Notably, the slow performance is only at night. Both devices generally show LTE with 2-3 dots (sometimes dips to 1 dot), regardless of the time of day. I downloaded the Ookla speed test to diagnose. Both devices show OK-ish download speeds at all times (1-4 Mbps), but the upload speed changes from adequate during the day (0.6 - 2.0 Mbps) to dismal during the 7pm - 1am hours (0.01 to 0.07 Mbps), which explains the poor data performance. Again, I will emphasize that the EXACT same speedtest results are obtained with TWO different devices, and ONLY during night-time hours - so it is absolutely NOT a device-specific problem. I am a daily data user, particularly during night-time hours, and these problems (again, involving both devices) have started recently, but they occur every night. My zip code is 21045 - no issues until now. Starting to suspect the rollout of VoLTE has something to do with this (all that extra bandwidth for voice has to come from somewhere, right?). Also starting to think it is time to give AT&T a try, if these upload speed issues are not addressed quite soon. Why am I paying Verizon for data, when I can't use any?
