iPhone 11 Pro - Bouncing LTE after updating to IOS 13.2

I have an issue with my new iPhone 11 Pro.

LTE is bouncing sometimes and unable to make call - carrier is unreachable.

Issue can be reproduced only on 11/11 Pro devices and only on ios 13.2

I made everything: clean install, reset, changed sim card, disabled Volte - no luck. When I selecting only 3G - everything is fine, exept 4G.

I made call to provider - Kyivstar, Ukraine, and got answer from tech department that issue only related with my device. Ok. After that I did downgrade IOS to 13.1.2 and voila - LTE started working as it should be.

Also I've found that issue affecting my iPhone only when I reaching cover B3+B7 base station, when I connected only to B3 station - LTE is ok.

Issue tested on: iPhone 11 Pro, iPhone 11 Pro Max, iPhone 11

btw: other ukrainan carriers: lifecell and vodafone are working fine even on 13.2.

iPhone 11 Pro, iOS 13

Issue has been fixed by mobile operator Kyivstar, Ukraine at one city - Kharkiv, hope other cities will be fixed ASAP.

I have also an issue with 4g in France with my iPhone 11. In some area it show full signal but it is not possible to connect to the internet i have to enable airplane mode to get back the connection but the connection fail again after a few minutes. Here we have issue with 4g even before iOS 13.2 https://discussions.apple.com/thread/250651248?answerId=251528916022#251528916022

Kyivstar, the same story. When I called the operator, I was told, that the support team hasn't received any significant number of complaints to confirm the problem.

I also tried temporarily switching to lifecell, everything worked without any issues.

I've made a video of issue, it affecting also eSIM attached provider, because iPhone has only 1 modem.

Affected Kyivstar coverage zones make boot-loop of iPhone modem, that going reboot continuously, while you not leave B7 zone or not switch to 3G only.

I have the same problem with IPhone 8 Plus, but operator is Vodafone Ukraine. It works fine Ukrainian Kyivstar or Lifecell. It happened after I had installed IOS 13.1.3. After installation IOS 13.2 it started to work even worse. Now I need to reload network after each call!
