I currently have a T-mobile Galaxy Note 7 V2 and I had the same issue with my V1 unit. I take the train to work and when I go into a tunnel for like 10-15 minutes I'll lose my data connection and when I come out of the tunnel, the Note 7 won't connect back to data. Sometimes it'll show an "X" by the signal status icon...and sometimes it'll show "full bars" but I still won't have a data connection. The same thing happens sometimes when I'm in the elevator at work...I lose connection in the elevator and then the Note 7 won't connect back unless I reboot the phone. This is extremely frustrating since it happens multiple times per week! I may just need to exchange this for a different phone if this problem can't be fixed.
There is also a post on XDA-Developers about this same issue that I've posted on as well. I just wanted to see if anyone else is experiencing this??
