Hello,
I've searched the forums and haven't found an answer to this issue I'm having.
I have a Huawei P10 Plus VKY-L29 model and I'm having issues connecting to LTE on T-Mobile US. In areas where is it supposed to be LTE, the signal displays "4G+". I know there's the argument that 4G+ is LTE but then there's the problem where other people are on LTE and I will be on 4G in the same area. Also, whenever I make a call (whether on 4G or 4G+) before the call begins to ring, it will revert to nothing higher than 3G and then connect the call. This is an issue because my phone will also not receive calls unless 3G is available (which is not always the case) and will send the caller straight to voicemail and I will get no notification that they called unless they leave a voicemail. I assume this is a VoLTE (Voice over LTE) thing. I want to note that I do have the Virtual HD call move enabled in Dialer settings. There is no VoLTE setting in the device though. I was searching for the engineering code for Huawei devices in case there's a "LTE/4G/3G/2G" option that is not enabled but have not found one that works for this device.
My device is not rooted.
Please help!
Thank you!

You have to check your carrier whether they enable and support VOLTE for P10 plus. My carrier in my country only support few mobile devices for VOLTE and including P10. VOLTE is a service provide by carrier. Not phone. Hope it helps.

I'm having some issues receiving phone calls when I'm in 4G mode - I'm aware of the fact that voice over lte doesn't work yet, however in my understanding the phone should quickly switch to 3g mode and accept the incoming call, right?
Apparently my P7-L10 has trouble with that. It just doesn't switch, and the incoming call goes to voicemail.
Is that normal? Is there any fix to make the device switch to 3g mode quicker upon a call?
Running B135 rom, rooted.

I'm having fine calls when I'm on 4G. (Milan, north Italy). Perhaps your city has too few 4G antennas and doesn't have stable 4G signal so it switches back and forth to 3G while you're having a call?

I don't think that's the issue, 4G coverage here is pretty amazing.

Forget what I wrote, I forgot that voice calls don't have to do anything with LTE, lol.
Anyway I'm having fine calls with 3G or 2G, have you tried doing a nandroid backup and start over to see if the problem occurs also in fresh state?
Fine calls with 3g or 2g here as well.
Except when I'm on 4G - nobody can reach me, it all goes to voicemail...
I could say I started fresh - I did a factory reset and a clean wipe 3 days ago, but I haven't noticed the issue untill yesterday.
On a French, people reported issues with calls in 4g covered area, but it seems that the problems come from network, not from the phone. The issues appear only in certain areas with one operator, and some other phones behave in same manner. Perhaps you need to check with another SIM card from another operator.
hello,
I encounter the same problem receiving my incoming calls in automatic mode 4G 3G 2G redirected my mail. When I'm on automatic 3G2G no problem.
I'm B133 update. 4 months no problem. Since mid-October the problem occurred.
My operator is Virgin Mobile. P7 smartphones, antennas or operator?
The rocker 4G 3G to receive calls no longer made. Tried my sim card on a S5 and a LG G2 and the problem is the same.
After several calls to my operator solution but not another concern, I have to connect data to receive my calls 4G 3G 2G automatic.
I'll try to go B121 update or réinisilisation P7.
If no solution change operator before trying their sim card lent by friends subscribers home.

I just bought my note 5. Its the dual sim version. So the first few days was days.... i started having difficulty with making outgoing calls... texts are fine... its like 1 out 10 calls would push through. So i rebooted my phone thinking that it might resolve the issue....unfortunately it did not. Then a few friends sent me a message that theyve been trying to call me and it always says im out of coverage are... the whole time this was happening I was connected to LTE. When i changed my mobile network setting to 3g/2g .... then calls came in and went out. Has anyone have the same issue with note 5?
The international versions don't have VoLTE enabled. Not sure how to enable it. Mine also doesn't have WB-AMR (HD Voice) enabled either.
Thus, calls need to be switched through the HSPA network and can't be routed while connected to LTE. Essentially when making a call your phone switches and tries to register on HSPA, quickly.
I'm experiencing issues with VOLTE on T-Mobile. My phone switches immediately from an LTE+ DATA connection to HSPA the moment a call is placed. Of course, VOLTE is enabled on the settings side. I'm running an unmodified system, upgraded to PIE.
I've been on the phone with T-Mo to make sure the APN is correct (nothing special to mention here). I've also tried different connection combinations using the *#*#4636#*#* with different results but, even though the phone connects really fast to DATA (LTE+), I cannot get VOLTE to function in any case. On the other hand, WiFi calling works just fine.
On a chat with Razer, they just told me that VOLTE is unstable with T-Mobile and, to disable the function altogether from settings.
Before I give up, I'm asking the geniuses here for ideas or experiences? Any ideas anyone?

I hope this can be figured out. Im waiting for my Razer 2 phone delivery and also on T-Mobile. What OS are you running? Android Pie?
Yes, I'm on Pie.
Good news! with today's update (3-20-2019), my phone is using VOLTE technologies to connect audio calls. Phone calls sound immensely better now (the "HD" icon shows up during the call and the "LTE+" connection indicator in the status bar remains through the call).
With AT&T shutting down it's 3G network in a few months I was wondering if anyone had been able to get AT*T's voLTE (HD voice) activated so we can still make voice calls on the network. I have the AT&T model (and am using a tracfone AT&T sim), and "search" in the settings does show an entry for "enhanced LTE services" but selecting it just takes you to the same spot as the "more" entry and there is nothing useful for voLTE. When making a voice call data drops out of LTE, down to "4G".
Using a t-mobile sim (via tracfone), defaults to voLTE, verified also by surfing during a phone call, and LTE symbol staying on the whole time.
Hmmm weird, I can get voLTE with another AT&T MVNO (unreal mobile) by default, with no issues (also tested by surfing during a call and having LTE symbol stay on). I was not aware there could/would be differences in voLTE support among MVNOs
Is anyone having an issue where the data network drops from 5G to 3G upon receiving a phone call?
On S21 Ultra, Telstra network.
Have tried Network Settings Reset without assistance, and the telco claims everything is enabled on their end.
I'm also unable to find the VoLTE toggle under Network Connections and cannot enable call waiting - I wonder if this is related.
EDIT: Turns out it was indeed a carrier issue. Resolved with call to Telstra.
It is definitely related. If no VoLTE is set, network will always switch back fron 4G or 5G to 3G to support the incoming call.
Setting to use VoLTE (or 'call via 4G') should be under Mobile Network settings.
You may want to check with Telstra support, as VoLTE may not yet be activated for your device/subscription or apn settings are not correctly set.
@OnnoJ Thanks for the reply. The call via 4G toggle is missing from my "Mobile networks" setting page. I've seen others have a similar issue, but have not found a solution as yet.
Can't believe it - called Telstra again and they now found VoLTE was NOT provisioned! They fixed it on their end and all is working.
