How to fix the phone calling bug issue? - Xiaomi Poco X3 NFC Questions & Answers

Hello,
I have a problem with the Poco X3 NFC.
Some times the phone seems to be disconnected from the mobile provider.
I can not make or receive any phone call.
I have to put the phone for a while to airplane mode or to reboot it to be able to make a voice call again.
I read that maybe changing the sim card fix that. I changed the sim but the problem still exists.
I have setup as prefered network the 3g instead of 4g but also this does not fix the issue.
Is anyone having the same issue? Is this a known bug that will be fixed with an software update from xiaomi or I have a problematic phone?
If there is a known fix, please let me know.
Thanks

Can't make or receive calls

All of the sudden I can't make or receive calls on my huawei m7, if I make a call it tries to dial for 10 seconds and then terminates. I get no dial tone, people calling me gets nowhere. Text messages work fine, 4G/WiFi works. I have noticed that if I turn 4G off I get no signal, so I have no 2G or 3G, I've tried factory resetting which did nothing. I've also upgraded to 5.1 and downgraded to 4.4.2, no difference. Also tries clearing the data on the Google apps as some people have suggested.
Anyone got some ideas what could help me with this problem? Would be much appreciated!
Thanks in advance
hey pal just change your network mode to 2g 3g( i mean deselect 4g lte wcdma auto connect from preferred network mode. because 4g lte is meant for data use only. I f your carrier and phone doesnt support volte. u cannot make calls over lte networks.) after selecting 3g 2g auto connect just restart ur phone and then check. I have same problem with my mate7. I fixed it with the help of google. Thanks google.

Lost Data Connections

Hello All,
I have this phone for about a week, i have one major issue with Mate 9.
Whenever I send or receive MMS messages, my cellular data connections would stop entirely. My remedy to this issue is switch on and off the flight mode, then everything would resume to normal (but i can't do this all the time). I have tried to reset APN and got a new SIM from my wireless carrier, but no success. Has anyone experienced same issue as mine? How do i resolve this issue? please help!!
same here, phone from Dubai, I am on T-MO

Can't make or receive calls suddenly.

Hey guys,
This morning, my Mate 9 stopped making or receiving calls. 4G data works just fine. I am on AT&T using the chinese version MHA-AL00, been using the phone for few months now without any issues.
When I go to Settings-> More->Mobile Network->Card1 Network->Preferred Network Type and set it to 3G/2G auto or 2G only, my phone doesn't have a signal anymore. Switching to 4G/3G/2G auto brings signal back right away but only data works.
I came across a thread with similar issue on mate 7 but tried what they suggested with no luck
https://forum.xda-developers.com/mate-7/help/make-receive-calls-t3245378
Any help or suggestions would be greatly appreciated! I love this phone, don't want lose it over this issue.
Thank you!
try change the sim card to the other sim slot and see what happens, i have two sims with tmobile and at the beginning my old sim was disconnecting for no reason I went and replaced it and problem was gone.
try airplane mode on, then off

Issue Incoming Voice call - Poco X3 NFC QJGMIXM [UPDATE]

Dear Friend,
I'm having trouble receiving a call
The problem occurs when the phone is configured as preferred LTE. If it is configured as preferred 3G the problem does not occur.
I only discovered this problem because many people started to complain that they were not able to call me.
I did everything to try to find the problem and I was not successful. I did factory recovery and also without success. I need to leave my phone on 4G because I use a lot of data network but this bug is preventing the phone from receiving calls.
Could someone please help?
MIUI Global
12.0.6
Note 1 (wi-fi off): It is not 100% of the calls that occur problem but they are the majority.
I realized that when the phone is with the screen unlocked the problem does not occur. When the phone is locked and the screen is off, all calls fail
Note 2 (wi-fi on): If the screen is turned off with the phone connected to the 4G + wifi network the problem happens and even turning on the screen the problem continues.
workaroud: Turn on the screen. Turn off wifi
Regards
[UPDATE]
I upgraded to version MIUI Global 12.0.7 and issue was resolved in parts
The problem only occurs when the cell phone is connected to the 4G/4G+ network and the wifi. In this case the phone does not receive voice calls either with the screen locked and the screen unlocked.
If the wifi is off the problem no longer occurs
