I am getting calls that go straight to voicemail. This does not happen all the time, but when it does there is no call log, just a voicemail notification. Searching the web and support calls to T-Mobile seems to indicate that it is because the Mate 20 Lite does not support VoLTE, even though the phone has the band support. When a call comes in, T-Mobile will try and drop the call from LTE to 2G/3G, fail and then send the call straight to VM. Cannot find a solution and it seems there are many people having this issue across many different brands of unlocked phones on the T-Mobile network.
Here is the odd part and why I think it might be the phone. I am getting insane battery life on the Mate 20 Lite. I charged the phone to 100%last night, went to bed and 8 hours later it was still at 100%. Last night I missed an important call that went straight to VM. No forwarders, call blocks, airplane mode etc. I also noticed that these straight to VM calls happen when the phone has been sitting/immobile for a while. Like the aggressive battery management is killing some service. This does not happen with a Xiaomi A2 that my wife is using.
BTW, I am connecting to band LTE band 4 and get near 40Mbps down when testing, so I assume I am getting 4G LTE.
The phone is still within the return window and if I cannot solve this, I have to send it back.
Anyone have a solution?
No solution. I have a similar problem where I live there is nearly no cellular reception and the only way to get calls is to be connected to WiFi which activates VoLTE / Voice over WIFI. Huawei Mate 20 Lite does not do it though. Why not?

I've seen a number of threads where people post about their device dropping network data connectivity, and needing a reboot to solve it.
My issue is a bit different. Occasionally (I've noticed it 3-4 times today) when I go to send a text (SMS) or to use a data enabled service like Hangouts, that my phone shows no bars at all.. not even just no data, but the bars are grey and there's a red x. I wait about 15 seconds and it reconnects, then another 10 seconds later, the data is live again.
Phone is a private sale and under 1 month old, and all the Stamina functions are off.. I do see that the "Queue background Data" is turned on, but I don't think this should effect, no?
Not sure what digits I should be looking at to know if this might be a hardware vs software issue.. build is listed as .93
Im no stranger to unlocking and flashing, but I've kept this stock cuz it's tight and I adore the battery life.
Suggestions?

check in settings in network and set your network to the one you use , like gm/wcdma /lte , maybe your phone is strugling to find 3g or 4g , try it , who knows it might solve the issue , ty
Been about a month since I posted, and I'm still experiencing this issue. I often thumb my phone on and it's not connected. I don't really mind waiting for the 30 seconds or so that it takes to jump back on the network, but it often means I miss calls, and since it's my business phone, it kinda bums me out to suddenly get a VM notification of a missed call even though it never rang.
Is there some sort of utility that I can use to monitor the network activity to see how frequently it drops, and for how long? I've looked into ones on Play but they don't seem to have a history, just something that shows what data up and down is currently being reported.
Sadly the only Sony store in my city (and I think the country - Canada) has recently closed for good, so I'm not sure how to go about warranty repairs...

I don't have a solution, but I can tell you that you're not alone. I've been experienced the same thing on my Z3C. I sometimes wonder if it has anything to do with the fact that the MVNO I use doesn't support 4G LTE.

Interesting.. Your issue isn't just data, but a complete network disconnection? Im with Fido which is an MVNO under Rogers, but I thought they supported LTE. The issue also persists even on wifi

Yes, it seems to be a complete loss of the mobile connection. When I wake the phone I see gray bars and a red X on the signal strength indicator. Within seconds the phone re-acquires and the indicator goes to 2 or 3 bars. I have also seen it happen with wifi active. The frustrating part is that it doesn't seem to do it often enough to troubleshoot. I'll notice the problem maybe a couple of times a month and there's nothing obviously different about my usage patterns in those instances.
Mine does it at least a dozen times a day. I can only assume this as I frequently miss calls and at least 3-4 times a day I see it happen. =(
Same Problem
Randomly I have no connection at all but after a few seconds everything wents back to normal. Did not have this problem with T-mobile in Germany but with with O2 I have. With T-mobile I had LTE but with O2 I don't, so I guess that's the reason.
Interesting... I've disabled LTE and now have it on 3g/GSM. We'll see how it works moving forward, and I'll post again in a week. Stay tuned.
Service Providers
In the mobile network settings one can change the service provider manually. With LTE enabled my provider has three entries: LTE, 3G and 2G. Connecting two LTE fails, because my provider blocked it in my plan. Having LTE enabled, it often tries to connect to LTE I assume. I switched off LTE and set the provider manually to 3G. Maybe that helps. We'll see.

Interesting.. I have LTE as part of my network and plan... But once I made changes to the settings as I indicated, I no longer receive the network drops I originally experienced.. I might just be missing the alerts, but it seems fixed... #crossedfingers
I'm having issues with calls and texts on T-mobile since this morning. Whenever I place a call the phone sometimes takes 10 seconds to ring, rarely it'll go straight to voicemail, and more often the call won't go through at all, the call will just drop.
If I myself end the call I lose any sort of connection, no 2g no 3g no LTE; I checked settings/about/network and Cellular Network Type gets stuck on UMTS. When this happens I can't call nor can I send messages, the redundant fix that I have to do to fix LTE and get messages working again is to go into: settings/mobile data/network operators and register automatically again, this always gives me LTE and messaging back, and sometimes calls, sometimes.
On the other end, when people call me, I noticed that the phone will go into 4g or H which is the same thing I believe. However, calls don't come through, it either goes straight to voicemail or it'll ring once or twice then go straight to voicemail. Also when it rings on their end, I can't hear it on my end, phone is silent.
This has happened on 4 roms Eragon, NusenSeven, Stock GP Edition and Insert Coin,
The phone is rooted and s-off
HBoot: 161
7.19.401.2
If anyone has the same issue or know a fix, please let me know, it's getting a tad bit annoying.
Hoping It could be the sim card, Thank you, much appreciated
Edit: Apparently T-Mobile was having issues in my area. Surprised it was out for 3 days.
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 recently changed to H2O, which is an AT&T reseller for those who are unfamiliar, and I'm having a very peculiar problem.
When I go to make a call, as soon as I tap the green button to make the call, sometimes my signal drops to 0 bars and I can't make the call. Sometimes this happens repeatedly and it's impossible to call anyone. But sometimes the call will go through after the 2nd, 3rd, or 4th try. However, sometimes it drops to emergency calls only after the call fails, or sometimes it drops to no service.
Additionally, when I go to change the conditional call forwarding under dialer - settings - calls - call forwarding, as soon as I tap call forwarding, the signal bars vanish and I get a call settings error. This happens almost all of the time. And again, sometimes it will drop to emergency calls only, or a several times I've had it drop to no service.
When I give up trying to make a call or change call forwarding settings, the signal strength will return after a minute or so, which is currently fluxuating around -112 dBm 28 asu, -116 dBm 24 asu, 110 dBm 30 asu. Not sure what any of that means though.
Frequently, incoming calls do not reach my phone. Often I'll get a text message asking me why I'm not answering my phone, but it never rang. There's no indication that my phone was out of service as there is always at least one bar.
I can send text messages with no problem at all. My data also works just fine. In fact, one of my friends gave up calling my phone number and instead calls me on WhatsApp because that's the only way he can get a hold of me. He would call my number, have it fail, and then immediately call me on WhatsApp and that goes through because my data doesn't usually have any issues.
I've tried changing APN settings according to different information I got from H2O. I've tried changing the preferred network type to 3G and 2G. Changing to 2G seems to help my ability to make calls, or maybe it just seemed that way. I've contacted H2O numerous times about it. They opened multiple tickets on it and finally said that there's no problem on their end getting service on that sim card. I sorta verified this because the sim card doesn't display this problem in my 1st gen Moto X, an XT1053.
Two other people in my house are on the AT&T network, one on Cricket with a Galaxy S6 (G920AZ), and one on H2O with a Galaxy S3 (T999) and they never have any issues here at home or elsewhere.
My phone is an XT1095 pure edition. I run stock 6.0, 24.11.18.victara_tmo.tmo.en.US, kernel 3.4.42-g389e46b, rooted, TWRP, with no apps that modify call behavior except Google Voice which is set to never use GV to make calls. This phone worked flawlessly on several different T-Mobile resellers. I'm about to switch back to another T-Mobile reseller but I thought I'd post here about this strange issue first because I don't want to always be limited to the T-Mobile network.
Any advice or input is greatly appreciated.
I would like to share a peculiar trouble with my S10 that I purchased 8 days ago.
At my workplace, wherein I have been working for about ten months, I am now experiencing major trouble in calling with this phone - the person at the other end is never able to hear my voice properly - in every call!
But, outside of my workplace, this problem does not occur at all! Voice quality is amazing.
I went to the service center. One of the representatives immediately advised a factory reset and fresh installation of software from their system. I got that done, but the problem was still there. Very poor connection!
I went back and another representative gave me an advice which has solved my trouble magically! Now, the call quality is back to normal just like i get outide my workplace.
The advice given to me was to change the Network Mode from LTE/3G/2G to 3G/2G. He had said that this new phone has more bands than ever and that it is possible that my workplace environment does not support the new bands (sounds illogical). By the way, the signal bars still show 4G icon but not Volte/LTE like in the other network mode. (And my last phone, Mi 5, never gave me such a trouble)
Although the problem was solved, but i wondered that changing the mode from LTE to 3G will have a bearing on the data speed. I used Ookla speed test to determine that and yes, there is a major difference in download speed - it is less than half in 3G/2G network mode.
Can you please tell me if there is a trouble with my device harware or was the representative right?
LTE does require a much stronger signal than 3g and when you default to LTE the phone is probably just getting enough LTE to stay locked in to the signal. The LTE signal is getting knocked down in your building. Also HSPA+ will propogate better than LTE, even on the same bands.
Thanks for responding. In all this while I've done a lot of research. I managed to ask someone to come with their S10 to my office. The calls went through with this S10 without any hiccups whatsoever.
Also, I've been using the same network in this workplace on Mi 5 without any trouble. Also, there are many S9 and S8 users in my office. They have never had such complaints and they call on VoLTE.
Also, I tried two other networks and the problem persists.
Clearly, there is trouble with my phone. It is with the service centre now for diagnosis but they have been claiming that the problem lies with network in my area.
At the service centre there was another customer with Note 9 who complained of similar call drops but in random locations. The service centre simply did a fresh softwareinstall and sent him back.
My problem is that I will never be able to prove to them about call drops since the drops do not happen at the service centre.
I've had many occasions where I'm on the phone and the call drops. I try to pay attention to the screen as the 6T was pretty bad for that (I would face hang-up all the time) and it seems better with the S10 but I still get a fair amount of call drops. If I even attempt to hold the phone with my shoulder, it's almost guaranteed it will hang up as the proximity detector will enable the buttons.
Keep LTE enabled for data, but turn VoLTE off so calls switch to 3G/2G
Did you try to use a different sim card?
