I noticed my AppleCare Replacement iphone 6s (Verizon model on IOS 9.0.2) has an issue. On my phone, whenever I do Cellular -> Enable LTE -> Data Only, my phone will go to "No Service". Already tried Reset Networking settings but not able to resolve the issue. Somehow the phone only works in "VOLTE/Voice and Data" mode, but not data only. However my older iphone 6 plus (on IOS 8.4) has no problem doing "data only" mode. Anyone experience similar situation? I also tried my SIM card on my wife's unlocked AT&T 6s plus (IOS 9.0) and it also works, so it is not a SIM problem. I suspect this issue is an 'Replacement' product issue. Earlier this phone also had the international SIM locked issue, which was resolved by Apple Engineering adjusted the activation policy. Not sure whether this 'Data only' not working issue is related or not.
