Hello,
I bought a mi mix 2s some time ago and it's currently running the china rom because I can't unlock the bootloader the next 10 days.
First of all I can call other people and I can use mobile data. Also I'm able to receive calls if the sim is in my old oneplus one.
Now to my problem:
Today I realized that there must be a problem if someone calls me but I couldn't really figure out under what circumstances the issue appears.
However, I could figure out the following:
If I'm on wifi calls work most of the time
If I'm on 4g I don't receive calls most of the time
If I'm on H+ I receive calls most of the time
If the phone is locked I either get the call or the mailbox answers
If I don't get the call there are two things that happen on the phone that is calling me:
If it's a samsung theres just one loud beep and the call ends
If it's a LG there are fast beeps (similar like if the phone is busy)
Thanks in advance for any help

EDIT: Just figured out that the problem is that the phone takes too long to switch from 4g to 3g since VoLTE is not supported by my carrier... Found some guys in a forum who complained about the same problem but with a oneplus phone... I'm still open for any ideas that could fix that Maybe someone from germany here who uses O2/Eplus network and got the same problem?
EDIT2: http://en.miui.com/thread-935378-1-1.html Used this to enable VoLTE but can't test if it's working until tomorrow
Fixed it by the way by enabling VoLTE with the miui dialer code explained here

Hey everyone, I just got my One S yesterday and found out last night that the incoming phone calls aren't coming through. I can receive and send text message and make outgoing calls. Any idea if this is a problem with the phone or maybe a t-mobile outage?

Why don't you call the store you got it from or call C.S you just got it so anything wrong with it could be handled with them. Have you tested it yourself calling from another phone?

I just realized that wifi calling works. I also just called t-Mobile and after 30 minutes of diagnostics they told me that there is a network outage for new activations. Since it took them so long to figure out there is a network outage, I think they are full of it.
Are you still having this issue?
My wife just emailed me saying she was trying to call me but the call wasn't going through.
I was immediately getting calls when I changed my SIM yesterday...

When I first turned the phone on and called to activate my new SIM, tmobile made a test phone call to my new phone and everything worked fine. But now that I think about it, I think wi-fi calling was active at the time. I haven't received any calls today so not sure if the issue is still there.
This happened to me when switching telco, I got a SMS from new operator with a date but no time when my number would be ported. On that day I could make calls and send SMS but not get any calls. Turns out my number had been ported to new telco without me realizing this (I was still using my old SIM since it seemed to work to me.) After changing to new SIM everything was fine. All of this was on a desire though so might not apply to you ofc

Update: The phone worked for 24 hours and now is back to not receiving phone calls. Anyone else experiencing these problems?

Sounds like you have a bad phone, call CS or take it back and demand a replacement.

Calls not coming through - possible solution
I had this problem when I first got it.
First under settings->call->Use Internet calling - make sure you select Only for Internet calls.
Now go to wifi and make sure you are connected to a Wi-Fi network - then click the More menu listed under Mobil Network (three dots). If you have wifi calling enabled, go to Wi-Fi Calling Settings->Connection Preferences and select Cellular Preferred - otherwise you won't be able to make calls when not near a Wi-Fi.
Hope this helps - it took me forever to track it down!

The problem is i can make calls, just can't receive them. I don't think it's the phone as when people call me it goes to an automated message saying i'm not on the network. Even my voicemail doesn't work.
Hey guys i have issue i cant get incoming calls but outgoing call is ok friends can't call me, i disabled divert and contacted my carrier they said sim have no problem but the issue is with your phone. I formatted it two times still no luck
Best Regards
Any suggest?
Are you running CyanogenMod 13 or any other ROM with LTE enabled? That might be the problem custom ROMs have trouble sometimes with VOLTE, try setting it to 3G and test it out
This thing really helped me . Go to setting , press network and there you will see Volt HD calls just simply uncheck this one and now you will receive calls . ENJOY
Hi I'm having no luck dealing with net 10, and I'm hoping I can get some assistance from you fellas here at xda . About a week ago my phone stopped making calls, when I try to dial out it says server unavailable. I can make texts when I send them it says sending forever but the text still goes through. I can receive texts , cannot receive calls and my internet works perfect. Net 10 is thoroughly convinced that I have a defective phone and after they have provisioned it 10 times nothing has changed . They had me factory reet, then after that failed has informed me I have a faulty device. So I bought another one and what do you know see problem .
Besides the fact that these people I don't think know anything about what they are talking about I am going nuts.
Here's what I have tried and some info I think may help
I have turned off volte and enhanced calling . Nothing happens .
My phone is the tcl lx
Net 10 Verizon sim
In phone info everything is right but voice network type says unknown
I have never seen this before but in shortcut maker I had 6 separate operator plugins activities. After whiping phone 2 remain the first just crashed second pops up a box saying switching to lte for better voice quility
Thanks I can provide any info if it will help
Using the device on T-Mobile. Sometimes I'll just get a voice mail notification - without the phone ever ringing. Tested from a desk phone, and sure enough it goes right to voice mail without ever ringing. If I make a call outbound from the Zenfone 6, it will always work. Then I'm able to receive calls for an unknown amount of time. I can reboot and get calls after the reboot, but they will eventually randomly stop.
SMS also come though delayed by hours. For instance someone sends a SMS my way at 2pm, I'll get it at about 4pm. If I send a SMS out bound, I then instantly get all the inbound ones.
Anyone know if I need to whitelist something in battery optimization? So far the Zenfone isn't really good at being a phone. - great at everything else though.
Check your apn settings I think I had to update the default to whatever BYOD APN settings are for T-mobile see if it helps you
Also had this issue on T-Mobile. If APN settings don't fix it, I'd go to Auto-start Manager in Settings > Battery > PowerMaster and allow your messaging apps to run.
For me, I'd get SMS messages only when my screen was on, and some weren't received from contacts, like it shuts the apps off after not using them.
Same here. I'm about to switch providers because of this. What rom are y'all using? I'm on LineageOS 16. @wreid23 can you post your APN settings?
Tried unoptimizing all the messaging related apps, no effect.

So I found that if I turn off WiFi calls come right through. I don't know what the fix is, but I guess that's my work around.

I've found the same to be true for me. Wi-Fi connection prevents calls from coming in. I can dial out just fine.
This is extremely strange since this phone is not even Wi-Fi calling certified and it's not even a feature. This has been my biggest issue with the phone so far because you never know if you miss a really important call.

I purchased a OnePlus 7T for this reason. Can't use this device anymore after getting flack at work for missing and oncall issue due to the phone not ringing because I left wifi on.

Asus denies the phone could be the problem (despite the phone obviously being the only variable). I replied to that thread anyway, with my experience of similar lost calls on a Moto x4 with Wi-Fi calling enabled. Maybe it'll give some engineer at Asus a push in the right direction...
if any of you are rooted there is an alternative for now to enable volte and vowifi: https://forum.xda-developers.com/rog-phone-2/how-to/guide-enabling-volte-vowifi-v2-t4028073

I'm having the issue with T-Mobile 7T Pro, when I got the permanent unlock approval and switched to Mint Mobile sim is when calls went to voice mail, have you found a solution yet? Phone works fine if I use T-Mobile sim, but Mint Mobile sim in the 7T Pro is when the calls go to voice mail and text don't go out, if I put the Mint mobile sim into a Pixel XL all is fine. When I had to quit Mint Mobile becasue of this and go back to T-Mobile on prepaid again, all worked well.
The zenfone 6 is getting volte with the android 11 update so hopefully that fixes this issue

Hi,
I have not been using my OP6 because of a strange issue with it since OOS 10.3.9 (maybe since May 2021)
This issue is: I can not make nor receive normal call with any provider. but my network bar is full and my 4G internet is running smoothly.
If I try to make a call, it just show the call screen, no calling tone and no waiting tone and the other phone doesn't ring.
If I try to call my OP6 from other phones, it just doesn't connect, no call tone no waiting tone... My OP6 also doesn't show any incoming call.
I'm sure my sim cards are OK, I have tried to put them in a different phone and they can make normal call.
If my sim card slots were broken, I would not have any coverage and my 4G wouldn't work...
I can receive SMS just fine.
anybody can help me?
thank you
I had the same issue, at the end oneplus said, bring it to a service center while there plenty or forum posts in their forums from technician saying it's the network chip, i got a new phone but will attempt to replace that chip once i got my replacement.
You could try other stuff, full wipe, other roms etc.
