I have replaced my Iphone 5s four times in the last 6 months and replaced the SIM card twice. Have done factory reset etc. For the latest test, I used a ping app and let it run for 30 min. with no packet loss... yet I loose internet connection.. Since I rely on VOIP to communicate (thanks T mobile for the terrible signal at my house), I can see when it drops out of VOIP. I hope apple fixes this problem sooner rather than later. It is a pain to have to "reset network" on the phone five times a day!
PS: We also have a Samsung Note 3 at the house and it has better T-mobile cell signal and never drops the network.. I like everything else about my iphone, but I may have to consider Samsung or LG for the three other phones in my household!
Apple, you are starting to look like Microsoft with premature releases that have not been properly tested.. Oh yeah, lets just use our customers for testing and be a reactive company.. we'll fix it after our clients identify the problem with an "update" and save all that testing money ie: the Microsoft business model... LOL
