Hi,
I have a H873 on Telus in Canada. Some calls go straight to voicemail in some situations:
If,
- In Advanced wifi settings, wifi is "on only when charging" AND
- Phone is locked for at least a minute
Calls go straight to voicemail, even if there are no wifi networks nearby.
If the phone is awake calls go through normally.
If wifi if off, calls go through normally.
I have no VoWiFi settings on my phone.
So far, I have resetted network settings. Didn't work.
I did a factory reset and set up the phone as a new one. Didn't work.
Went in the hidden menus and pu VoWiFi to 0 (default was -1). Didn't work.
Changed the sim card. Didn't work.
I wasn't able to change network. Will try next week.
Network at home does the same thing that the one at work. They are both using Ubiquiti antennas but I am using an open network at the office (I first thought of the the WPA2 channels or encryption method).
I previously had a S7 Edge on the same network with no problem. Had a S8 for a couple of days to test the device. every device worked correctly. Only the G6 does that.
The phone is on the latest security patch (july 2017). Not rooted.
I wonder if it's software related or hardware. Device is unlocked. I will turn off VoLTE, seems like the next logical step.
Any resolution?

Guys this is a very difficult one. I really appreciate your help. If there's any place I can get an answer I think it's here.
My Nexus 6P had the Wi-Fi: option in the settings, I saw it many times. However after activating the phone with Sprint (during the process the agent Keith something into my phone which caused it to download and install something from their system) the Wi-Fi calling option is gone from the settings. I've tried everything I can think of to get it back and have been unable to.
I have a very new Nexus 6P running 6.0.1. I purchased this phone especially for its Wi-Fi calling capabilities to use on the T-Mobile network. At the time of purchase there was a lot of conflicting information about Wi-Fi calling coming from T-Mobile's customer support/technical support and numerous support people were saying the 6P is the only phone they were sure would work. I used the phone on T-Mobile's network with Wi-Fi calling and the Wi-Fi calling worked flawlessly, but there were other problems with their service so I moved on to Sprint. Sprint's Wi-Fi calling was horrible, in fact I don't think it was really doing Wi-Fi calling, I think it was just calling to the cellular network. During my time with Sprint I noticed that the phones Wi-Fi calling settings were gone. I contacted Google and they said that if Wi-Fi calling is not allowed by the carrier then the option would not appear in settings. I don't know if that's true but that's what they said. I assumed moving onto Verizon which does offer Wi-Fi calling would restore that option if it was just a matter of having a Sim card which commanded the phone to enable Wi-Fi calling. However after switching to Verizon I still have no Wi-Fi calling settings, and I am unable to make Wi-Fi calls.
In an attempt to get my Wi-Fi calling features back on the phone by factory wiped the number of times from recovery, I also upgraded to android N beta, I also routed the phone and tried installing Cyanogenmod, I also installed pure nexus, I also returned back to the stock Marshmallow, and nothing restored the Wi-Fi calling option on the phone.
I believe what the Sprint agent dialed on my phone to cause it to download and install something from their network is ##72786#, though the agent also dialed ##873283# and ##675#.
One of the Verizon technical support agents suggested that I dial *#*#72786#*#* but when I do that nothing happens except what I dialed clears out of the dialer. I used one of the apps to discover secret codes on my phone and it shows that code is handled by an application called SprintDL. I know some people whose Nexus 6P have never been on the Sprint network also have that application, so I'm not sure if that is something that was installed during the activation process with Sprint.
Now I'm wondering if I need to reflash the vendor information or the radio modem information part of the ROM. It seems like all the roof flashing that I've done would have flashed over everything that could be flashed. But it does seem like something happened to my phone, something was installed or changed or replaced and whatever that is is surviving through multiple factory wipes and ROM flashings.
Sorry for going on, but I want to pass along everything up front so I don't receive irrelevant responses were requests for more information.
I will be so grateful of anybody can help me out of this mess. I live in a place with very poor cellular coverage and Wi-Fi calling is critically important. If I have to send this phone back to Huawei all have to purchase another phone to use in the interim.
Thank you in advance.

Verizon only offers WiFi calling for approved phones on there network. I do not have that option either with my 6p on Verizon however my wife's Galaxy S7 does.

Surely you jest. But of course.
Honestly, do you think someone who's rooted their phone and has flashed a number of different ROMs wouldn't know or how to look in the settings?

Thank you so much! So you mean that:
A) your phone has the Wi-Fi calling option in the settings but it does not work with Verizon?
– or –
B) because you are on the Verizon network the option for Wi-Fi calling does not show up in your settings?

I do not have the wifi calling option in my settings. I've always been with Verizon so I haven't tested it with another network to if that would change. I wish I checked to see if it was there before it was activated but I didn't. I'm fairly sure the option just doesn't show up if the network doesn't support it.

Thank you so much! That is so great to know! I know that my setting for WiFi calling was there because I received the phone and played with it before I activated it and the setting was there. It was there when I was with AT&T and with T-Mobile.
I just found out what the problem/solution. It's the sim card. Today I purchased a T-Mobile sim card and even before it was activated, as soon as I popped it in my phone presented a notification about wifi calling and sure enough I checked the settings and the wifi calling option was back.
So if you have a 6p and the wifi calling option is not visible it's because of your sim card. Removing the wifi calling disabled sim card, rebooting the phone, reflashing the rom/firmware does NOT restore the visibility of the wifi calling option. The only thing that will restore the visibility of the wifi calling option is to insert a sim card that is wifi enabled.
I wish the good folks at Google or Huawei knew that the wifi calling setting's appearance or disappearance is tied to the sim card. It would have saved me a lot of work and headache
So having installed the sim from T-Mobile got you back the Wi-Fi settings back but when you put back the Sprint/Verizon sim did it remove it again or not? And if it didn't did Wi-Fi calling work on Sprint/Verizon? Or do we have to call and order a Wi-Fi enabled sim from our carrier?
My phone is doing very strange things and not working right. I have LTE data, but it will not connect to 3g and I can't do SMS or calls. I'm on Sprint.
I was in Japan for a bit trying to use the Sprint roaming plan. My phone stopped connecting after two days and I spent a lot of time trying to resolve that connection issue, including a factory reset and doing the Update device config and Update PRL many times with no success.
Now that I'm back in the US, my GSM/CDMA still hasn't been working. I have again done the SprintDM updates as well as doing *#*#72786#*#* SCRTN reset and letting that finish, but it still doesn't work. Has anyone seen this issue and know any way to fix it? I'm on stock software too
I'm having this same issue, after a Sprint MVNO did a service update that required all their users to SCRTN. I was originally without LTE, too, but going through *#*#4636#*#* > Phone Info > Dots > Select Radio Band > US at least got that to work - but only that. Voice Service is still "Emergency Calls Only", Voice Network Type "Unknown". I have reset and reflashed this thing countless times, with no luck, even got a new SIM card, and the account has been reprovisioned on their end.
Hey, I'm assuming there's at least a handful of you on BOOM! Mobile (Verizon)? They recently rolled out VoLTE on the Verizon network, but I'm having trouble getting it to work.
First off; I had an issue getting them to activate my Moto X Pure on their network (apparently mine is still on Verizon's "blacklist" like many were when this phone was first released). After much strife with their customer support, I just ordered one of their cheapo phones to activate the SIM, then popped it into my Moto X. No problem. They called later because the different IMEI apparently threw a red flag, but updated the info in their system and all was well.
So to get back to VoLTE, I had to fill out a form in order for them to activate the feature on my account, but got a confirmation email that it had been activated. I still didn't get the "advanced LTE" option in the cellular network settings on my phone, so I used the secret phone menu to "turn on VOLTE provisioned flag". This made the option appear, already enabled. However when trying to place a call, I immediately get "Server error. Try again later". Radio restarts, sets the VoLTE flag to off, and I can place calls as before.
So has anyone had better luck with VoLTE on Boom? I understand it works on Verizon, correct? It did work when I was on TMO. I'm completely stock 6.0 unrooted/locked. I suspect it may have to do with Verizon thinking my device is "incompatible"?
Ok... I screwed up! There is a new Verizon tower near my house and I wanted to update my roaming, so I did the *228. Alas, by accident I chose option 1 (Program phone) instead of option 2 (Update roaming). Immediately after that I lost LTE. 3G is the best I now get.
I am running 7.1 latest update. Not rooted.
Suggestions on how to get LTE back up?
Thanks!

That describes steps if I were using Oreo but alas, I am on Nougat. I will look for similar issues.
Thanks!
Tried the recommended steps. Worked for about an hour. Then back to 3G. THEN noticed I could not send a text message! GROAN...

Try this:
*#*#4636#*#*
Phone Information
Change Preferred network type to LTE/WCDMA
If after cycling your connectivity it doesn't pop onto the Verizon 4G network, reboot your phone, you should be good then.
I dont know what it is about that setting that is different, because Verizon doesnt support WCDMA, however this seems to select the correct type of LTE connectivity and you'll be in that. Be aware though, this will likely prevent 3G from working if you enter an area without good 4G coverage.
I have tried all recommendations. LTE works for a while then it is back to 3G. On a further note, when this happens I cannot send a text message but a reboot will solve the text message issue.
I am at a loss. It seems there is no way to make the settings accessed by *#*#4636#*#* STICK.

It not just you. I have been frustrated for weeks. I thought it was only because I upgraded to 8.1 but your situation just answered that. I just ordered a new SIM from Verizon and wont run any programming once I install it. I contacted Essential on it as well as others. I hope the two can work this out.
Best option is a new some. *228 is usually no suggested on LTE unless you really know what you are doing. The PRL should be automatic on LTE.
get a new sim, your is borked now most likely
Will try new SIM tomorrow and let you know...
A VZW rep had me do *228 when I was having some issues with texting when I first got the phone. Fixed the texting issues but then I couldn't get LTE either. A new SIM fixed both issues I was having. *228 is apparently known to bork VZW LTE.
Had the same issues after using the *228 method I advise not using that at all been stuck on 3g since. Getting a new sim thursday hoping that helps (using straight talk Verizon Sim)
Here is a bit of information I have discovered. The phone is stable as long as I NEVER turn on WiFi! IF I have WiFi turned on (no connection to a network required) AND I enter a poor or non-existent service area, I loose service until I go back in with the *#*#4636#*#* and change settings back yet again!
anyone with a new sim got it working? Verizon shipped me one today and put it in. Avoided calling 228 but cannot get the sim to activate itself.
Got a SIM not provisioned error. I turned it off, took the SIM out and checked it, put it back, rebooted and still nothing. Not connecting to Verizon Network. Im afraid to call support because they will insist to call 228 to program it.
BTW the final version of 8.1 fixed all the Verizon weirdness I had going on. I popped it back in 'Global' in the Mobile Network settings (which is equivalent to 'LTE/CDMA/UMTS (PRL)' in the Phone Information section) and it hopped immediately on to Verizon, no kinda looking like sprint, no blank, no need to dial *228 for a new PRL it just worked. In fact on reboot it doesn't sit there with No Service scrolling across the screen for 15-20 seconds after boot, it shows up Verizon Wireless immediately.

That's good to hear I switched to an old straight talk TMobile sim I had while I wait for the replacement straight talk Verizon version hoping things go as smoothly for me when I pop it in

Very frustrating for me. This is my only concern with this phone . Im still stuck in 3G after doing the upgrade, hard reset, and popping in a new SIM without dailing 228. I will change my Mobile Netwok settings to yours above.

May you should try reinserting your sim my phone self corrected once my update was done.
Here are my results:
Installed new SIM - same issue
Did a network data settings reset
Verizon did a flush and reinitialize of my account.
Still same result.
Don't know exactly how or why but about 10 mins later I noticed my phone was OFF.
I powered back up and MOST issues we're gone.
The final fix was to go into developer options and turn on "cellular data always active"
Working great on LTE+

Try putting it in "4G/LTE", wait for it to connect, then back to Global.
After I posted my above message, I did go mucking around in the settings and got it stuck in 3G (even after reboots, etc), then corrected it by doing this.
And quick clarification for the post above this one, it is "Mobile Data Always Active", mine was already on and I never modified it, so that must be the default.
I've got a very weird issue with my Galaxy S8 (SM-G950FD)
After working fine for about 1.5 years on the network it suddenly wasn't able to make and receive calls anymore on the Lebara (Vodafone) network in Australia.
The issue spontaneously disappeared a few hours after it first surfaced but reappeared and has not gone away since.
Internet and Txt/MMS are working normally. But when someone calls me it goes straight to voicemail and when I call nothing happens for a minute or so and then it "disconnects" but no tone
When I go into the phone app and try to retrieve settings like caller ID and/or forwarding it gives the following error:
Failed to read data
Something went wrong. Check your
Sim Card or network connection,
then try again
When I insert the sim into an S7 it's working. When I insert the sim from the S7 into the S8 (Optus network) the S8 works as well.
I've performed a factory reset (without restoring the settings)
I've gotten a new sim and Lebara has ported the number to it but that didn't help
Being a dual sim I've tried using the shared sd/sim slot but same issue.. data/mms/txt working no voice.
I've tried copying the apn settings the S7 displays with the Lebara sim to the S8 but that didn't help either.
I've now used Odin to flash the phone back to the Oreo version with the December 2018 security update and that didn't help either.
Any other ideas?
Thanks
I've managed to narrow down the issue a bit.
Also went out to purchase a Vodafone Pre-paid sim. That one didn't work either at first but after some troubleshooting with support of Vodafone we've found out that the S8 doesn't connect to the 3G network of Vodafone Australia.
When I have the SIM of another provider in there and limited the network mode to 2G/3G autoconnect the phone just finds the 2 other networks on 3G (AFAIK 2G has been phased out).
I've tried to get into the advanced service mode but this doesn't seem to be possible anymore.
Is there a way to try to see which bands are active on the S8 and better yet enable them all?
