Hello, I have iPad 9.7 pro and every 10-30 min it looses cellular connection LTE and reestablishes it 2-3 sec. later. I tried 2 SIM with Att and 1 SIM with T-mobile and I have the same story. I tried reset it to factory settings and it just lost cell connection again. I have latest iOS 9.3.4 on it. I had the same problem with 9.3.3. Any advices here? I hate to exchange it in Apple store, may be I can do something else? May be it is 24.0 carrier settings? Did anybody fix the issue with iOS 10.0? Any help is appreciated. Thanks guys!
