** TITLE MEANT TO SAY WIFI/LTE** I have 2 separate Iphone 6S's both on the sprint network on different sprint accounts. Things I have Tried: Airplane On/Off ##Clear# ##UPGRADE# Do Not Disturb Is OFF ( Tried turning on and off) Clear Network Settings Both phones are having identical issues and are owned by 2 different people so they are in different areas of the city and houses etc..etc.. Both phones have issues receiving phone calls when they are on LTE..... the caller will hear ringing but the phone itself doesn't vibrate/ring. If the caller leaves a message the phones WILL receive the Voice Mail Alert. If the phones are dialed 3 times consecutively....the third call goes through. I haven't tested this to see if it works 100% of the time.( again, do not disturb is OFF). If the phones are swtiched to 3G they receive the calls EVERY TIME. Additionally I notice the phone has trouble when switching between LTE>3G>1X the phones fluctate alot of 3G to LTE and down to 1X often. I also have Iphone 5s and I notice that phone is on LTE with 2 Bars and the 6S is only on 3G with 4 Bars. And Finally the phones will drop to 1X sometimes....and then just be stuck there until I do a Airplane/Off. Any Ideas?
