Cellular Network Unavailble for Voice Calls / SMS after Android 10 Update

2020-09-23, 1:06 AM

Last week, my One Zoom updated to Android 10. Since then, I have been unable to make or recieve voice calls or SMS, however my data service is working fine. I swapped my SIM into two other phones and was able to use voice calling and SMS on both other handsets. 

 

I have searched various forums and follwed directions related to manipulating various settings however nothing has worked. I read that some people have been able to solve similar issues by disabling VoLTE, however the Android 10 update seems have to remvoved this option from all settings menus. 

 

I am currently based in China and connecting to the China Telecom network. I had no issues when the phone was running Android 9, so it seems to me that the issues is with the 10 update. My build is QPH30.28-Q3-28-13-1. 

 

Thanks in advance for any advice on solving this issue! I'm hoping to avoid a factory reset / downgrade back to 9. :)

I got the file via Removed

You need the specific firmware for your version, so be careful it's not supported

Hi, thank you for your help. 

 

https://drive.google.com/file/d/12EkCCOE0LVzcle9UaXOo-X4i1bnV9k5f/view?usp=drivesdk 

 

I have updated my profile with my IMEI and Motorola privacy boxes are both turned on. My carrier is China Telecom however that option was not listed on the profile section. 

 

Just before taking the bug report I attempted to make two phone calls, to two different numbers. Both times I was greeted with "Cellular Network Unavailable for Voice Calls" message and the calls did not connect. I'm also unable to send or receive sms messages but my data connection is fine. 

 

Local time was about 1130 am on September 30th.

 

Thanks again, hope we can solve this!
