iPhone 6S Plus have "no service" signal?

[striders]

Since I upgraded from iPhone 6 Plus to 6S Plus, I have seen the "no service" message on places where I normally have good signal. These are places that I frequent for the past few years (home, work, restaurant, etc.) in different cities, so I doubt T-Mobile (my carrier) have issues with all the transmitter in 8 different cities at the same time.

Hence, does anyone experience this issue? The "no service" appears at random and I either have to reboot the phone or turn on/off Airplane mode.

Interesting.. I don't get "no service", but I do get a 4G signal in places I used to get a one-two bar LTE signal on my 6S+
