Hello everyone,
I have Mi 9 M1902F1G 128gb with MIUI global 11.0.4. I am living in France and using Bouyuges telecom, recently when I come to work my phone loses network connection related to simcard. No calls, no 4G, no 3G nothing absolutely. There is a cross sign sometimes on network bar, then sim card activation process starts but no connection. Even I cannot send an sms. This is a new problem. I have been using this phone with same sim card for approximately for a year.
Thanks in advance

Since you don't tell us what actions you already have taken the most obvious is to pull out the sim card and clean it. If this doesn't help, contact your operator to get a new sim card. Everything you say indicates that your problem is one with the sim card or the operator and has nothing to do with the phone.

Have you tried with VoLTE disabled?
Also, by preferring network type 3G or even 2G, instead of 4G.
Maybe you recently got some some 4G/3G micro-station at work with the band not supported by phone
Edit: You could also try to inspect by Network Cell Info Lite, Net Monster, Net Monitor or similar apps available from Playstore

Hi Guys,
I'm using Airtel India network (karnataka)
I'm unable to get 3g connectivity from past 6 days and as we all know 4g is not supported in Nexus 6.
Only 2g is getting connected and surprisingly my sim card is working fine with 3g network with other handsets i checked.
I have tried contacting airtel several times and have not got any response apart from stating that everything is fine at their end.
I just wanna know if this a handset problem or the network issue ?? and how to fix it
Does anybody else facing same issue?
Just to clarify something, the Nexus 6 does have 4G. It displays "LTE" on the signal strength meter when 4G is connected.
What steps have you taken to diagnose the problem? We have no way of knowing whether the handset has gone bad or the network is having problems without some work from you. For instance, have you tried a new SIM? Have you checked your APN? Done a factory reset?
Well my Nexus 6 didnt pick up signal from my sim card. Sim card is working in other phone so visited the service centre and they inserted another sim and the signal was not picked either. Now the phone is in service centre.
Now for the surprise part!!!!
the other phone which i inserted my sim card is a new box piece of MI redmi Note 3 which worked fine until now. Now i'm getting 3G symbol in this phone as well and nothing is getting connected. lost LTE connection and not getting connected.
LTE never worked in my Nexus 6 and was not aware i could use 4g in Nexus 6 since i am using 4G enabled sim and never got LTE connectivity (PS i stay in India).
I'm lost now.
Your SIM could be damaged. It's not common, but SIM cards do fail. I had it happen on another device and lost voice and data until I could get a new SIM. Fortunately for me the SIM didn't damage the equipment, which again isn't common, but possible.
The fact your new device is exhibiting the same symptoms as your Nexus and only doing so after inserting the SIM leads to one inescapable fact: your SIM is damaged. When your Nexus is returned to you, get a new SIM.
Nexus 6 does support LTE in India through 1800 MHz Band, ie Idea and Vodafone.
Airtel is using 2300 MHz which is not supported by the Nexus 6, that's why you are not able to latch on to Airtel LTE.
Hello. About a 4 months ago i have bought from eBay a note 5 at&t version. I live in Greece and my network operator is WIND GR. The phone works fine but from time to time i get an emergency calls only message. And i can't get and do a phone call. If i restart the phone everything goes to normal. Sometimes it goes on and off by itself (the problem).
Have been anyone experiencing the same issue? If the phone is incompatible with my network operator should it not work at all?
Did you tried to change the sim card? Maybe issue is from sim or from sim slot

My sim is new. When i purchased the phone i have changed my old sim with a new sim 4g compatible.
It happened again. And i am missing calls like this. I will smash it with a hammer
Go to settings, backup and reset, then reset only network settings, see if any better signal

Done that right now. Tomorrow i will get a new sim card and i will post if anything gets better. Thanks for the help.
Update of the situation. I have changed sim card 2 times. It still happening. My phone runs at nougat now and the problem still appears as before at 5 and 6 Android version. I currently gonna change service provider that has better and stronger signal. From what i have discovered. When the phone looses signal due too poor service provider signal sometimes it can't register to network by itself. If i enable airplane mode and then turn it off it comes back. Any clue? If it's hardware issue what can i change?
Should i have at the mobile networks auto detect or manual and my carrier?
Hi guys, I have a note 8 and it is previously sim locked thru a carrier back in my country. I have used samkey to sim unlock my my phone and it work like a charm using other sim card from another carrier however my problem is I can't use 4G LTE data using a different network but I can use it to call and text. When using my original sim from my previously locked carrier I am able to use DATA 4G LTE. I have searched for solutions in the internet but no luck at all. Please help. Roaming charges are very expensive and I really need help as I use the mobile internet for navigation abroad. Thank you in advance guys!
Maybe try with the new sim in your phone to reset the network. Go to settings - general management - reset - reset network settings. This will also delete your wifi passwords and such though. But I had a problem with my phone (N950N) to use with a different sim in it, that it would only connect to 3g, I did this and finally got LTE working.

Check your APN settings.
Google: "Cricket APN" ! Frist line of results...
Hi guys,
My toy is a samsung note N 9600 and its factory unlocked. Last week ported out from T-mobile to keep my original number and facing a wried issue.
The day I ported out from T-mobile, VZW network couldnt be recognized when I tried to activate the VZW sim card. "No network connection." and no call or text can be made. However, after I RESET my device to factory model, it SUCCESSFULLY recognized VZW and LTE function works well. Sounds wried? The story doesnt end here.
Yesterday after I turned off the VZW sim card by accident-- n9600 is a dual sim card which allows you to turn either sim card off-- the network connection lost again, im not talking about LTE connection, but all network service including internet, phone call and text function. Tried a lot to get the connection back but failed. Guess what? RESET, THEN VZW comes back!!! Being driven by curiosity, I turned off the sim card agian, and then, as my expect, no network connection. Ok, rest---works---turning off sim card---no connection---reset……
I am really annoyed by this and have no idea why it is. So if anyone of you have clue of it, plz let me know. Thank you in advance!

No one experienced same issue before?
So One thing I discovered on this new phone of mine is that although working perfectly there is a major flaw in the way Internet data works during a phone call.
Any time you make a call, the phone downgrades the active signal from 5G/4G to H or E ( GSM).
Which in turns cuts off the data.
If I force 5G or 4G, then the phone call cannot be made. It just disconnects.
I have tried all settings, Volte enable/disable with no joy.
Some have said it's a carrier limitation, but it's not, cause in my iPhone, the very same simcard works just fine and the Internet is usable during a call.
Also tried with dual Simcard setup. As in the settings, the phone allows to use one simcard for data and one for call. Still not working.
Can someone please tell me if there is a solution please, or can you try your phone while on the call to see if Internet works as this feature is detrimental to me keeping the phone. If this doesn't work I will be selling the phone and getting a realme replacement.. Xiaomis sometimes suck with their non existent support.
Thanks

This comes from the operator who has not yet communicated with Xiaomi.
Same case with 2 operators on the same phone.
What version of rom?

Global ROM 13.0.4
I can't see an operator fault if they have Volte services enabled and this simcard works flawlessly on other android systems.
As a matter of fact, any SimCard i have tried, so far 3 providers and the phone does the same thing. As soonest the call is made it downgrades the signal to H while full 5G or 4G is available??

the operator must provide the necessary information for each brand and phone to activate Volte and Wowifi.
On my 11t pro everything works with SFR and nothing with FREE because Free has not yet transmitted the information necessary to activate the services.
So went to see the operator. They sell Xiaomi phones. 3 network ( Three EU)
The phones in the stores are working just fine, no issues at all. And my phone simply just isnt.I have tried every possible setting and still not working.
See the screenshot below. As I'm typing this I'm on a super fast full signal 5G connection. As soon as I make a phone call, the phone will downgrade to E or H+ which is horrible. This network signal switching is also laggy, and If 2g signal is poor I cannot even make a call.

Does the "Use VoLTE" switch appear in the SIM card settings?
If not you can try the Dialer Code *#*#869434#*#*. That only will make this switch appear, but sometimes this is enough. It should also show the little VoLTE-Badge next to the signal strength (see screenshot).

I just had another look and on your 1st post it says the SIM is named "3 IRL", as far as I know Three Ireland does not offer VoLTE at all.
So it will always drop to 3G/H+ or 2G/E ... on every phone.

5G connection should support this naturally. If I put this simcard Into an iPhone or Galaxy the 5G connection stays on regardless.
Anyway even with Vodafone this doesn't work,so I'm thinking it either a phone limitation or a phone is fooked

No, for VoNR your phone still needs the same configs as with VoLTE. Though only a few operators support VoNR as of now.
