As the title says I'm having trouble when using 4G/5G. All incoming calls are shown as Unknown. When you force 3G/2G only, caller number is displayed normally. Searching google there are many reports with other phones as well having this issue when used with VoLTE and most of them were fixed with software updates. So I contacted my carrier and told them to disable VoLTE from their side. Unfortunatelly I have no slider in Sim settings to disable VoLTE myself.
After VoLTE was disabled from my carrier all incoming calls were displayed normally. It's not the best solution cause I bought this phone specificaly for this reason, to use VoLTE/VoWifi.
I posted the issue on bug tracker of realme as well.
Currently I'm on A.05 version and I have no idea how I could change to another version to test if it would work.
Any help would be appreciated regarding this issue.
PS. I tried factory resetting several times. Clear data/cache of phone/contacts app as well and tried with another dialer.

Incoming and outgoing calls are shown as "Unkown" (Custom ROM and living abroad)
I recently installed the Exodus Rom on my Sprint Samsung Galaxy S5 and then moved to Mongolia.
Now, all of my incoming and outgoing calls are listed as "Unknown"
I believe I fixed this in the past with another phone and it was very simple, but I just can't remember how I did it. Any advice?
PS I really enjoy the Exodus Rom
I read that fixing permissions may help..... but couldn't that also mess up my phone?
Anyone? I know this is a common problem, but I can't seem to find an answer anywhere.
Seems to be a service provider problem. Either you are not being sent the caller id, or your phone is unable to read the send id.
Had a similar problem when i moved to Germany from India and calling up the service provider solved the problem..they activated the "show caller id" which was not activated due to some reason.
Call the service provider and tell them your problem...it most likely will be solved. Let me know if it does

Actually, If I don't use a CM based mod it works fine... It is only on CM based mods. I went to a service provider store and they punched in a code... but it didn't fix it. They were confused and told me I should have my phone fixed.
Hi
I just bought an XZs dual SIM version. I'm having a very strange issue with it.
I have two SIMs installed: one on O2 UK and the other on Three UK.
The three chip works perfectly. Can do everything, voice, data, SMS etc... all good.
The O2 chip however has a strange issue. Every phone call I make it says "Invalid number".
Even if I call using the international +XX XXXXXX type or if I call using the UK style 07XXXXX both say "Invalid number" and do not complete the call.
What is odd is that I can receive incoming calls to the number. SMS and data also works, just making outgoing calls fails.
I checked that the phone supports the bands that O2 uses and it does. It does connect to the network (as I said I can receive calls, use data, send and receive SMS but just cannot make any outgoing calls)
The phone came from Hong Kong, and both O2 and Sony have flat out refused to help because I didn't buy the phone in the UK.
But well, it's a mobile phone, it should work in my country even if it's from HK.
I cannot really understand why I can receive calls but not make them. The SIM card works in my UK Samsung S6 so I do not think it's a network issue.
I have tried setting it to GSM only as it is my work phone and I really only need it for making calls. I've tried WCDMA / 4G / 3G but nothing fixes it.
I have reset the phone. Checked carrier settings etc.
Lastly I have tried swapping the chips around, and tried it with just one SIM but still the problem occurs.
Please can anyone give any suggestions on resolving this issue before I have to send it back ?
Thanks!
never mind. i solved it.
it was a provisioning error by the network, contacted O2 today and they resolved it by doing some kind of reset their end, which they didn't want to elaborate on.
fixed now.
I´ve activate the VOLTE, and all the receive calls appears as Unknown.
Anyone with this problem?

I'm like you but I back and choose uk Vodafone and it's works for me maybe you could try it
Me too.
I'm from Portugal and even OnePlus 7 Pro not showing in their compatible devices it worked flawlessly till the last OnePlus update, and a factory reset that i had to make due to other situation.
Now, if i have VoLTE activated, I still can use 4G during a call but the name and number from the caller shows "unknown".

Hi there,
I've been searching the internet for someone with a similar problem but nothing helped me.
My phone : POCO F2 Pro 8GB version
What's happening?
The phone functions normally except for text messages. Most of the time they are just stuck on sending . I've had some success by clearing all data from Google Messages app , uninstalling updates and rebooting the phone but this is just a temporary fix (sometimes works for 20 minutes and then stops but most of the time it just doesn't help).
Things I tried:
- Changed the SIM card
- Put another SIM into the phone from a different carrier (worked but I only tried it for like 10 minutes)
- Tried a different messaging (Textra) , this worked for a limited time.
- Looked for anything off with the SMS Center Number but it's set correctly
What I noticed :
When logging into Mi Account, it tries to send a verification message but always fails . I logged out completely from the account but nothing.
I know it's not from the carrier since it worked fine with my old phone (S9+).
Could this be hardware related?
Thank you very much
Did you try to move SIM from Slot 1 to Slot 2, and then back? Redmi Note 5 had this issue for me, from time to time I had to change slots...
So far, on PocoF2 I don't have any problems with SMS.

This might be a different topic altogether ... I have strictly this topic, I can not activate my SIM card with MiCloud services. To activate it, the SIM tries to send a SMS to a +44xxx number and my carrier does not have a commercial relationship with +44xxx network, so the SMS is restricted by my carrier and not sent. Other than that, my SMS sending/receiving works fine.
Update : look like my phone sends texts normally without any problems to specific numbers like my work phone
Hi. I have the same issue. The problem is existing only when the VOLTE service is enabled. Try to move on 3G only or just stop Volte under 4G and it will be ok. Unfortunately Xiaomi are using some specific technology for volte sms sending and the your network provider does not support it. The phone is trying to send SMS through SS7 instead of SIP protocol when VoLTE is enabled. I'm trying to find a hidden menu where I can eventually switch or choose a protocol but without success.
I have the same problem too. did you find the solution?
Disable the chat feature in the messages app. That worked for me.
unfortunately it does not help, only after turning off the volte and restarting the phone it starts sending

Heyy man!!! Really appreciate your help for this fix!! I can send sms now if I turn off volte!! But that's too much to lose for just sending a text message... please update us if you find any permanent solution for this!! Respect+++++
Device: Poco X3 (indian)
Hi, i just upgraded my phone from vivo y19 to Xiaomi Poco x3 Pro. One thing i noticed about this phone is that, it works fine in almost every department except for one thing. The SMS messaging. I notied that whenever i send sms to some one, it takes too long to send and the result is they keep receiving my text multiple times. Sometimes 10x somtimes 12x, and its really annoying especially when i send sms to my higher ups at work. My network carrier has good connection, all apps are updated, even the firmware is up to date, but the problem still persists. I already tried using 3rd party sms app, hoping to fix the problem but its still the same. Already tried factory reset but the problem is still thesame..
anyone having the same issue? Im kinda frustrated lately because of this..
I have different issue on Poco M3. SMS works except that *some* incoming messages are eaten by MIUI and never arrive in inbox. Have disabled chat option and spam protection, tried with Textra too. Biggest problem on that issue: it is not reproducable, every time we try make some test it works. Have disabled VoLTE now, not sure it has any effect

This is not the right place to post, the problem may be similar but the phone is different.
There is a thread for your phone here or here .
if you want help it is necessary to give basic information such as rom etc ...
And the first thing to do before tinkering is to reset the phone.
I don't think phone model matters as this is some issue with MIUI 11 and 12 (also on Poco F1 and M3)

Poco f1 and M3 are on V12.0 poco f2 v12.5 and the last post for this problem dates from 2020.
Not the same firmware.
I have an unlocked originally-T-mobile OP9, with Android 11, and I have an issue with Google Fi that I couldn't find online references to.
Every so often, I can't make calls: the dialer starts to dial and then stops within a fraction of a second. A reboot always solves the problem, but then the problem comes back eventually. Data works fine.
Update: I can't receive calls in this state either.
I tried using the beta Google Phone dialer, and maybe even some third-party dialer, and the issue is the same.
killing the com.android.server.telecom:ui task solved the problem without a reboot, and now I have a Tasker shortcut to do that on my home page, but that's not really a viable solution given that incoming calls don't work when the issue happens.
Does someone maybe have a version of Telecom.apk from a different firmware that I could try?
A bit more experimentation: When the phone is in the bad no incoming/outgoing calls state, if I turn off mobile data, or switch it to 2G, everything works again. Then when I switch back to 5G, calls don't work (but data works). Is it a VoLTE issue?
Bump... Am I really the only person on XDA using a TMO OnePlus 9 on Google Fi? Is anybody using an international OnePlus 9 at least? I might want to change to international firmware then.
Well, I think I've solved it by installing international firmware. My guess is that the problem had to do with VoLTE support in the T-Mobile firmware.
