Came across this discussion recently: https://discussions.apple.com/thread/7244825?tstart=0 There doesn't seem to be a solution, nor an acknowledgement from Apple about an antenna problem in the 6S family. I wanted to know if anybody else based in PH was experiencing this issue or if it's isolated to just my phone. Basically, I lose signal when I'm on the move. My wife, who uses an iPhone 6, doesn't experience the same problem. TBH, I only started noticing it when I started playing Pokemon Go. But I've also experienced losing signal while using Waze, so I'm afraid it may be a phone problem. My 6S+ is brand new, btw (bought May 28, 2016 from PMC). I've been in touch with Apple Support but all their suggested solutions have not worked (i.e. new SIM, restore from backup, restore in Recovery Mode). PMC is asking me to leave my phone for 1-2 days so they can try and replicate it but that's not an option for me at the moment.
