When you make a call, does the network stay on 4G or does it switch to 3G ?

So you haven't got VoLTE. Maybe it's a slow fallback issue. If you receive a call while you are on 4G, the phone switches to 3G or to 2G and, if this switch is too slow, the caller sees you as not reachable.

Try with another SIM with a different network, so you can understand where the problem is.

Apologies for bumping an old thread, but I'm facing this issue as well. The phone simply doesn't ring when a call comes from certain numbers. I've confirmed that these numbers are NOT in the 'blocked list' in Phone app.
The only way to know that a call is missed is to open the Phone app and see that a number is blocked. Happening with 2 different Mi A2 devices in the house
Has anyone figured out a workaround?

Disable spam protection

Apologies for a late reply. Disabling "Caller ID and Spam" in the Phone app does not seem to help. Am I missing something? Is there any other way?

I am in 3G.
I have no problems when putting my sim in my tp2. And talking while surfing.
And i am not the only one. No one has givein a reason as to why.
Uh..unless you changed you radio settings to "WCDMA only" you should be able to talk and surf.
It should work. I do it all the time, but it is network dependent.
In case it works on your TP2 i suggest you check your settings.
Hey big guy are you using a t-mobile nexus one on AT&T? Or AT&T N1 on T-mobile? That used to send all my calls to voicemail while I was on the intarwebs

Incorrect. "WCDMA only" is still UMTS/HSPA (3G/3.5G in consumer speak), therefore you still get voice/data at once. I can only conclude that you're under the assumption that UMTS/GSM work the same way EVDO/CDMA does. On an EVDO network, all data goes through the EVDO network, while voice stays on 1xCDMA, because EVDO is an addon to 1xCDMA.
UMTS and GSM are two completely incompatible technologies that only share GSM backend features and a SIM card. The circuits in the phone are separate, the antennas on the towers are separate. You're either completely on UMTS for voice and data (inc. both at the same time) or you're completely on GSM (for voice or data but not both at once. In fact, if you're locked on to a strong UMTS signal, the parts of your phone that handle GSM shut down for power conservation and only wake up when your signal drops to check to see if you'll get a superior signal over GSM. It will do this periodically, but won't stay active for long unless your UMTS is so bad that you won't be able to hold a call. THEN your phone powers up and maintains the GSM radio, while putting the UMTS radio on standby, only powering it up momentarily to look for a better signal.
The only time you have GSM and WCDMA/UMTS powered on at the same time is during hand-offs from one network to the other. That's why staying in areas where you bounce between the two kills your battery so quickly, the radio is drawing roughly twice as much juice as it normally does, plus it's computing which one will do the better job for the moment. Even then, at that time, the phone and its OS will be using only one of the networks at a time, and if it's UMTS, you'll be able to hold a call and surf the web.

TMO on TMO.
Attached are my settings.
I have this on every rom or radio i try.
Hey, sort of same thing just happened to me
in my case using GSM Auto (prl) or WCDMA prefered I can connect to HSDPA but GSM is in emergency calls only, weird.
but I can do both on GSM only (GPRS/EDGE)
Re-flashed to official release of 2.1 same thing.
i use voice and data on my nexus at the sme time every day. it just works. as long as you have a 3G symbol next to your reception bars, then it works.
i dont know what you could have done to break this. can you demonstrate to us what you are doing that is not "working"?

I am connected to 3G network. Call comes in. I can not browse on the internet. While i am on the call i go check settings and i have droped to GPRS. As soon as i hang up i go back to 3G (HSDPA)
Have you ever changed your build.prop file at all in the past? If so that's the problem. Change to hsxpa=2 to fix it.
If not then I have no clue.

It is.
I have no problem on my TP2.
I use it often too but today I was unable to it. Hopefully its because my area is being updated to hsdpa+
i think i have the same problem. 3G drops during voice call, doesn't connect during the call. reconnects after the call ends.

When you have bad reception, that's what happens. Normal and expected. During the call it won't re-negotiate 3G, only when the call ends.

Yeah, that is normal and it really sucks when you're on a long call. Once you lose 3G signal it's gone for good. I don't know if it's a network problem, or the phone, but it should be fixed.

[Q] [Help] Signal problems

Hi.
I have a problem with the signal of my S3 Mini, actually only in my house I think, I mean only in a same place all time. The signal icon show 3 o 4 lines of signal but if I try to call or send a message, didn't work. Just don't call and dont send message. I try to change the firmware with another modem, flash the latest modem, but the problem don't solve. I've got the i8190L with a unbranded firmware, no custom rom.
Anyone know how can I fix this problem? Thank and sorry for my inglish.

Well, thanks you for your reply but befor an exahustive research I find the solution, or apparently solution. Just change the Auto GSM/WCDMA to Only WCDMA and the signal comes to my phone and now I can call and send messages.

Yes, This have nothing to do with rom or modem. It's an issue about the signal strenght. Concrete walls?

Did you go onto the verizon website and enable HD calling feature? Until you do this, it will not work.

Thank you for your efforts to help.
I activated it on the site.
I activated it on my phone.
I set my network to CDMA/LTE.
I make sure I'm on 4G LTE
I call someone.
Lose 4G.
Those are all my steps.
Perhaps I disabled an app that is required?
Also, do calls progress as normal or is there an intermediate screen?
When I call 611 I get a "Connecting" screen.

thats not true. Its only true to use the advance video calling if the other person has the feature. Wont effect the usage if another person doesnt have it. Just wont be able to use video chat

no thats not what it does for me. What i recommend doing is a factory reset.
To anyone in the future who has this same problem:
0) I correctly followed the steps to get Volte and nothing worked.
1) Factory reset did not fix my problem.
2) No one I talked to knew what they were talking about (surprise surprise).
3) I reached someone (Keshia) via chat and she deleted all my features and then re-added them - this fixed it.
4) ???
5) I can make calls and still be on 4g now. Praise the Lord.

My phone sometimes doesn't receive calls or texts.

My phone periodically doesn't receive calls or texts. I've tried resetting it. The calls don't show up in my missed calls but the voicemails do show up. I'm using the international version of the Note 8. Anyone know a fix?
Does the data drop out too when this happens? Try taking your sim card in and out again. Might be a problem there.
Have you got any do not disturb settings on?

Nope the data stays on. Outgoing calls work fine as well. All the do not disturb stuff seems to be off.

Are you rooted or did you install any custom roms, etc.?
I have had this issue with several phones, the culprit has been always the type of connection, sometimes even if full bars showing, I have to switch to 2g or 3g, 4g and 3g having the issue, 2g working always fine, dont know why, but I have learned to live this way, this happening since my S3, so, In my case is carrier signal fault

What networks are you both on? If it is the same, that may be your answer...
I would check with the network to see if the masts are under maintenance.
I wrote a post here in March 2018, but, some time later the issue diasppeared, from june, all is fine, in the end, I think it was the carrier that was working on the transition to 4.5G to implement their VoLte calls service
I have this same issue and with the same phone as well
I have the same issue, and i think it as to be with the position of the phone... when its down missed more than when its on vertical... could be just coicidence but its the only thing that i note

No Incoming calls when on WIFI... Help!

Hi Everyone. I have the Pro - CLT-L04 on MetroPCS .
I found an issue and wanted to know if anyone else had this issue.
When on WIFI, I do not receive any INCOMING calls, people tell it goes straight to voicemail. Soon as I am off wifi, it works fine. I can make calls, but cannot receive them. This happens about 90% of the I am on wifi.
There are no setting to play around regarding WIFI calling or any of that.
Any suggestions?
Same here. Orange wifi calls in belgium.

I don't have the issue, but it sounds like it could be related to VoLTE or Wi-Fi calling.
Try to turn Wi-Fi calling on or off and see if it might help.
