Reply to Cellular Data Connectivity iOS 14.0.1
Model: iPhone XS Max Issues since 14.1, currently 14.2: cellular data: not at all or very slow upload speeds (less than 1 mbs), not at all or sometime good/very download speeds (0 or 250 mbs). calls without wifi calling toggle active can get disconnected during the call or the other person cannot hear me while I can hear that person very well. Carrier signal is at max level (4 bars) and there are no apparent issues with wifi or bluetooth. I did everything! Literally checked every possible root cause: Potential cause 1, the carrier: tried physical sims/ e-sims same sims in samsung worked like a charm different carriers for each sim called all of them, no reported outages on their side problem still there Potential root cause 2, the phone: Spent more than 5 hours with apple support on the line while we went through all the steps (up to complete restore) and sent the full 30 mins diagnostics conclusion: no hardware / software problem recommendation: go to an authorized apple service provider did that, but they also didn’t find the problem (unofficial/ personal note from them: ios-related) installed the 14.3 beta 1 and 2, same problem Since not everyone with XS Max is having this issue, I would assume it was something I did that may have caused this; there are two things I have in mind: 1. iPhone had ios 14 beta installed on it since it went public around June. 2. Always had a mdm profile installed for running work-related apps (and yes, of course I removed it when doing the tests). I really believe this to be an iOS related issue and I hope the engineering team is on top of it.
