Sim card disappears after 2-4 minutes when making calls with VoLTE enabled - LG V20 Questions & Answers

My v20 drops all calls between 2 and 4 minutes in, and usually around the 3 minute mark. The call drops, signal goes to zero, and a moment later I get a toast message saying "Loading SIM card contacts..." and then I can immediately dial back in.
WiFi calling is disabled, though the setting being on or off doesn't seem to make a difference. I've cleaned the SIM card and added tape to the back to ensure good connectivity - no change. I also went to T-Mobile and they replaced my SIM on the spot but it immediately happened again in the store and in front of the clerk when we tried a call. They've suggested a warranty exchange.
One interesting thing I've found though is that disabling VoLTE calling fixes it entirely - it no longer drops calls, but of course there's no HD voice and I can't use band 12 and they're already cutting back on HSPA coverage.
Haven't found anything else useful via Google or XDA. Even with VoLTE enabled there are no data drops, VOIP calling via hangouts works fine. Anyone have any ideas short of a full exchange? Not rooted and while the LG backup app is pretty good, I really don't want to go through the day-long process of restoring everything if I can avoid it.

Hey there! I had the same issue, exchanged the phone for a new one, and STILL have the same isssue! Did you ever find another fix? This is so annoying and I cant believe a bigger deal isn't being made of it.

Been owning V20 for about 5 weeks now. The first 3 weeks were pleasant until I started seeing dropped calls. Disabling VoLTE did not help. Changing sim card wouldn't help either.

I'm having similar issues H915 Freedom Mobile.
Was roaming on AT&T in the US when I first did the update. And everything was fine till I was home and on Freedom.
When Wi-Fi calling is enabled. It makes no difference if mobile preferred or VoWIFI preferred is selected. It enables either way after reboot or turning Wi-Fi adapter off and on again.
Incomming calls frequently don't come through regardless of whether vo wifi is on or off. Texts same problem. And persists sometimes on cellular and sometimes on VoWifi.
Get SIM errors, signal drop constantly. And have tried everything I can think of to rectify the issues with zero success.
Anyone with Freedom having similar issues? Or any suggestions I might not have thought of that may be the the cause?

No data after having WiFi enabled for a while

Hello,
I've had this issue across more than 1 device and more than 1 carrier.
Here's what happens:
I enable WiFi, and for a while everything works as expected. I can send and receive MMS messages. I can disable WiFi and go back to my 4G connection.
The problem is, after an unknown amount of time, the phone drops the 4G connection in the background. I only know when I can't receive/send MMS messages anymore. At that point, if I disable WiFI there's no 4G data connection, and I have to turn Airplane mode off and turn it back on.
This is really annoying. It happened to me using Sprint and a Galaxy S4 (both stock and custom ROMs) and it's happening to me with a Galaxy S5 from MetroPCS. (I've used the stock Metro ROMs, Stock T-mobile ROMs, and Custom T-mobile ROMs).
Right now I'm using a Stock T-mobile ROM with the latest firmware, carrier is MetroPCS.
What can I do so this doesn't happen? It's really frustrating.
Thank you for your time.
Disabled "Smart Network Switch" in WiFi Settings?

Disabled "Smart Network Switch" in WiFi Settings?

Hello.
That's already disabled.
Should I enable it?
I tried with "smart network switch" enabled and disabled and problem still happened.
My S5 G900F Android 5.00 (Smart Network Switch disabled, Power Save disabled) on EE UK has had this problem for 9 months after phone upgraded itself to Lollipop (EE win the accolade to being the SLOWEST ON THE PLANET to provide Android updates.....). Since Jan 3, my wife's G901, a couple of weeks after it upgraded from 5.0 to 5.02, has developed the same problem. Neither phone has ever been rooted or other.
I have fruitlessly searched everywhere for a solution without success. EE Customer Services Tier 2 & Samsung's own service centre have failed to fix it. EE & Samsung blame each other for 5.1 or 5.1.1 not being available for download. Neither is prepared to resolve the issue despite hours on the phone. Have tried Safe Mode, Factory Reset, clearing everything, reloading APNs & Samsung even reloaded Android. All a waste of time: Many many days of it!
After approx half an hour connected to Wi-Fi, only way to get the mobile data to connect, is either reboot, enter & exit Air-plane mode or flip the 4G > 3G > 4G connection under More Networks. Have tested the fault in different cell areas countries and continents; fault is same everywhere.
It seems there are quite a few sufferers of this problem.
Samsung S5 keeps losing data connection
I have the same problem. My new Samsung phone loses the data connection (even though data is turned on) and I can only re-connect by restarting the phone. The first EE shop I took it to couldn't help at all. The second gave me a new SIM - that didn't work. Then I tried online support and after 3.5 hours of my life, in which I was passed on from one person to another, they completed a factory re-set - which didn't work (and additionally lost all the personalisation of my screen and some of my contacts). So I now have a not-very-smart phone which I have to re-start every time I want to use data. This is a business contract and the phone is less than two months old, but I'm not getting any effective support from EE. Android version is 5.0.2
me too, since last update. and app 'phono' shows "mobile data off" not got a time on it, but when i leave wifi coverage, it wont reconnect to cell data 2g/3g/4g. flightmode toggle to restore.
Abandon hope if you have this intermittent mobile data problem!
...at least until there is a software update, though I have no idea if that will help.
I have now tried a new sim card, a factory reset, and a replacement phone - which was provided only because I'm a business customer and I found a sympathetic member of staff. *By the way, I was told that if you are personal customer they won't consider replacing your phone if it is more than a month old - even if you started complaining about the phone as soon as you got it, the chances are a month will have elapsed by the time they put you through the hoops of a new sim, reset etc - and then it is too late to insist on a replacement phone.
In any case the replacement phone didn't resolve the issue so I have reached* a dead end. My phone fails to connect to data after having been connected to wifi - you have to do it manually each time you move away from a wifi connnection. At first I was doing it by restarting the phone, but am now following the advice of someone else who has the same problem and am going into flight mode and out again. *
This is not satisfactory, and it seems from reading forums that EE are to blame for the problem rather than Samsung, but I'm not 100% sure about that.*
Possible solution that works, for me, at the moment!
Having suffered this issue of my S5 (SM-G901F) not connecting to mobile data after being on Wi-Fi for a while unless switching airplane mode on/off for a few weeks; although it has probably been happening since the update I received late December; I have tried all of the turn this switch off, factory resets (x2), etc, etc, etc. and Googled the issue without success.
I have found this thread interesting, and I even tried calling EE support only to be told "you have tried everything that we would tell you to do" and "it wouldn't be a sim card, or handset issue, sounds like software". The reply was basically that like-it or lump it until the 5.1 update is released "by Samsung not EE because EE do not release Android updates". [Perhaps EE don't release the updates, but the stock rom is tested by them and their bloatware added before they eventually release it!!!]
Following my last reset I tried selectively re-installing the apps I used incase that was causing the issue. No Luck!
One last thing I tried was to look at every system 'thing' that I could find which used/switched any part of the mobile/mobile data/wifi - in addition to the settings I had already tried (all of which were mentioned in this thread previously). One thing I could not find not mentioned here, or anywhere, was the VoWi-Fi call on/off which I had always set to on as I do not live in a great reception area. Calling over Wi-Fi is great when you don't have a strong mobile signal.
Having 'played' with this setting for the last 24 hours I have found that the VoWi-Fi on/off appears to be a possible cure - for me anyway.:fingers-crossed:
When VoWi-Fi was set to off and leaving the phone connected to Wi-Fi overnight, the S5 immediately switched to mobile data this morning when I turned the Wi-Fi off . It continued to switch between Wi-Fi and mobile data all morning whilst out and about in and out of Wi-Fi connections - Woop Woop!!!
I then tried switching VoWi-Fi on (with Wi-Fi on and at home), leaving the phone for a number of hours, only to find that when I turned Wi-Fi off the phone refused to connect to mobile data even with a 'decent' mobile signal. The only way to get it to connect was to go back to switching Airplane mode on/off.
Switched VoWi-Fi off again, left Wi-Fi connected, left the phone for a couple of hours, etc. and hey-presto immediately switched to mobile data when I turned the Wi-Fi off. [Dances around the room because he's got the S5 automatically switching to mobile data again. Even though I'm at home with a great fibre internet and strong Wi-Fi connection!!!]
I do not know if this could be a solution for the others who are suffering from this issue, but it appears to be a solution for me at the moment. I thought I would share as your previous posts have helped me and you all seem to be pulling your hair out; like I have been; trying to find a solution.
Try it, it may work, but don't shoot me if it doesn't!
It's encouraging to know that I'm not crazy. I've had this issue across two devices and carries.
John,
Thank for your suggestion about WiFi calling. Unfortunately, I always have it off! I never used it, so maybe I should try turning it on? We'll see lol.
At this point, I think this is going to be my last Galaxy line phone.
Is it wi-fi calling that's causing the problem?
I have wondered if there is a link with wi-fi calling, but haven't tested it properly. I signed up with ee and bought the Galaxy phone specifically so that I could use wifi calling, as the town where I live (in the Scottish Borders) doesn't get a mobile signal strong to work reliably indoors from any of the networks. I'll try turning off wi-fi calling to see if that sorts the data thing (though I see that for one person above it did not). That would mean I wouldn't get calls or texts when I'm at home so it would not be a permanent solution for me. But in fact the wi-fi calling is not reliable anyway....

You never know the way things are going with this issue; given that nobody seems to be able to pinpoint the fault; turning it on may just sort it!!!

[Moto G4 with Amazon ads] Always losses carrier network after 24 hours

Hello everyone,
I just bought a Moto G4 16 GB with Amazon Ads for my wife, but we are facing a very annoying problem: the carrier signal always dies after 24 hours give or take. We tested with a different SIM card and the same thing happened. When this happens the device only shows "Emergency Calls Only" and we have to reboot the phone in order to get the signal back.
So, is anyone else facing this problem? Is this really a problem with this phone in particular or every moto g4 has this problem? Should I return the device to amazon?
Thank you very much for any information you can give me!

No problems here since I got my phone last week and I have T-Mobile. You might have to check your apn settings with your carrier.

I tested the SIM card in a different phone and it worked flawlessly (I also use T-Mobile). The strange thing is that the phone gets the signal very well during more or less one day, after that I have to reboot to get signal again.
Well, this is probably a problem in the device. I already asked Amazon to send a replacement.

Thank you, but I just use the t-mobile network. In fact, my carrier is called campusSIMs and it is a MVNO that uses t-mobile network. So, my APN configs are a bit different from yours.
However, I didn't know about this mobile data thing. I didn't touch the developer options. Maybe, it can be a good idea.
Thank you!
It won't be your APN settings since that controls your data settings. If the sim is ok then it could be your phone.

I'm seeing a similar problem with the data portion of the network (also on T-Mobile). While I'm able to send and receive calls and texts, data doesn't work. There's no indication that it's attached to LTE or even 3G (just a standard signal bar with no other information). I moved the SIM card back to the old phone it was in and it works fine.
Things actually worked yesterday, so something happened overnight to break it.

That could possible be the APN settings. Although usually it's the opposite, they don't work at first then they update from the network later on. Most times the APN settings will set themselves but on the odd occasion they need to manually edited. I don't use T-Mobile but the APN settings are easy enough to find.

Sounds like you need to manually enter the APN settings. What you describe is exactly what happens when it hasn't loaded an APN.
I'm "kinda" having an issue here. It's a little different though; the phone works ok for a while (for me about 3 hours, usually), and then I still get an LTE indicator, but have no network connection (get errors in apps/"No internet" page in chrome).
Other times, I lose LTE and get locked in 3g (H indicator), and can only get LTE back by going to Settings/More/Cellular Networks/ and toggle preferred network mode to 2g or 3g, let it connect (H or E), then toggle back to LTE.
Motorola responded to a bad Amazon review requesting I post asking for help on their forums.

I'm active over on their forums also and it's good to post over there in case you ever want to do a soak test. They look at your posts there when they ask for soak testers. As for your problem, I've seen it shift back and forth if you are in an area between towers and one isn't sending out LTE. If it were that I wouldn't think you'd get it back so easily. There's an app, don't remember the name, that will show the towers and signal relative to your location, If might be interesting to look at that.
Having the same issue with radio. Just replied to your post, Kalash.
Ok, we got a new phone from Amazon and it has the same problem. So, I believe this phone does not work very well with MVNOs.
I notice that the problem is that the phone cannot reconnect to the network after losing the signal. For example, if you go to an area with bad signal and, eventually the signal vanishes, the phone will not be able to reconnect to the carrier network. The phone only reconnects after reboot. Airplane mode does not solve the problem.
This does not happen with my Blu Life One X. So, I think it is a software problem.

That's not true on all mvnos' apparently. My wife's phone is on Consumer Cellular, an AT&T mvno and it's never done that. We've been in a no service area several times and it's always connected immediately when getting service back.

lost cellular data

So, when I woke up this morning I noticed my cell signal strength icon was one I haven't seen before. I tried rebooting and toggling airplane mode. I also verified that my sim is working in another device. I attached a screen cap with the icon.
Noticed something similar with mine. I had to turn wifi off, restart to get LTE data (verizon) then turn wifi back on. If restarting with wifi on the LTE data doesn't register.
that didnt work for me
update: had to factory reset, looks like verizon doesnt like that essential ph1 wont take all their bloatware, etc. might have to return the phone if this keeps up
My data connection has also become very erratic - and I've lost voice+data (VoLTE connectivity) wholly yesterday. Worked fine with the activated SIM from my HTC 10 from the 31st to yesterday.. Now, not at all, I've not been able to restore it since.
Really don't want to return it, as I really like the phone, but this has nexus 5x issues written all over it for long term use...
Hoping essential can get a certification and an agreement with Verizon before my return window is over (or at all)..
Pretty disappointed in Verizon here.
Sent from my PH-1 using XDA Labs
Same here, another issue is that essential shipped my phone and within a day i had an email from essential saying that verizon certification is still in progress. verizon will probably not certify it with their system unless essential lets them install their monitoring crap all over the phone.

The Nexus 6P didn't have the bloat and worked fine.
My PH-1 works fine including Enhanced 4G LTE Mode.
What do you have selected for network type?
I have the first one selected because that's the only one that includes the various CDMA protocols, EVDO and LTE.
I see the same connectivity that I had with my Nexus 6P.
i have global selected, as it covers everything the phone can connect to. i had the first one selected but it wouldnt show the lte+, just regular lte. i also have Enhanced 4g lte mode on. it just happened to lose service earlier today. if it does it again, ill probably return it after a visit to vzw

I have the same settings as you, I had functional "enhanced 4G LTE" for the first 4 days as well... That ended yesterday morning abruptly, and I'm not able to bring it back.. There's more happening here.. How long has your device been on the Verizon network? Only a hunch - in a few days you won't have "enhanced 4G LTE" either, even though it'll still be checked, and provisioned for it.

Cellular network is not available
After 7 days my phone won’t make calls I can only use data I’m on sprint and it was working fine until today I call sprint they had no answers at all I email essential no answer now I can only use WiFi calling while home and axx out at work
So, upon further digging I found a place to look at some more in-depth stuff relating to signal stuff. I did some fooling around and switched it from unknown to lte/cdma/umts auto (prl) and it seemed to work after a few moments of time. Though it seems have gone back to t he unknown state again but is working normally for me now, so maybe it was changing states and then a reboot?
How I got to this screen was by punching *#*#4636#*#* into the dialer, and went to phone info
I'm having a similar issue. I often lose my signal. I will have the full triangle/bars but no label of the signal(LTE+/LTE/3G/1x/etc....) and no cellular data at all.
The only way I can get it to return is to restart the device. Happens a few times a day, can't be 100% sure why, but it often appears to be when switching from WiFi -> Cellular only.
I have Verizon, I have had a Nexus 6 and then a Pixel XL for the past 3 years, never once had this issue.
I had constant disconnects and lost of service with my Tmo sim. Tried my Xfinity (VZW) sim and it was great until this morning. Complete lost of service. Airplaned mode on and off, connected to old school RTT 1x.... lol This phone's cellular just plain suck for a lot of us regardless of carrier. Not sure if we just have bad phones because apparently there are those who claim they have great service and connection.
I'm having this problem with Verizon. Seems like if I'm on wifi for a long period it only connects to 1x and putting in airplane mode and stuff won't get it to re-connect to to LTE. Only a reboot seems to fix the problem.

You might check out my post from the Oreo Beta thread... I was having some goofy signal issues early on which I've pretty much cleared up by doing what I mentioned here. Someone touched on it briefly earlier but only mentioned monkeying around with the settings, said nothing about picking up a new PRL.
I state this in that post too, but just in case: I offer this with no express intent of warranty, if you screw up your device, it's on you.

I had, right after writing this, tried *#*#4636#*#*
I set it to global as instructed in another post. The next time I drive a distance in the car I'll have to see if I have the same issue that only a reboot would fix again.
Thanks
I had the same issue and I resolved it a little differently than the previous posters. I turned on adb debugging and logged into adb shell and user-disabled com.redbend.app. This stops the Sprint oma-dm service from running. After doing this I no longer have the issue of my device not reinitializing lte after sleep or 3g.
I have essential on vzw but my only issue is my device won't connect to 4G. If I change network to LTE I get full 4G service but I'm unable to make phone calls. Went into vzw store and they told me you didn't get the phone from us so we cant help you. Day 14 fml
On Xfinity mobile, I had similar issues. Great LTE but sometimes calls just don't work at all. I mess with various settings and it'll work for a bit then so again. Gave up and ported over to Sprint for the free unlimited year which is still probably not worth it. Should've kept with Xfinity Mobile. Lol

Wifi calling - inconsistent with 8.1 Oreo - T-Mobile

I'm finding that WiFi calling stops working randomly. A reboot gets it to work properly again. I have my advanced call settings on Global and Wifi Preferred as my option.
Anyone else having this issue with Oreo 8.1 and T-Mobile?

I've had this issue since I upgraded to 8.1. I've been planning on doing a factory reset to see if it fixes the problem, but I really don't want to go through the hassle of setting everything up again.
I have no cell signal at my desk at work, so I use the WiFi calling often. However, I have noticed something rather strange. If I try to make a call or send a text, it will sometimes say something like "No WiFi network available". There have been a few times after it has done this that I have received a call on WiFi, and then it will work fine for a while. Otherwise, a restart fixes it.

Another thing that I noticed is that when on Wi-Fi calling, sometimes the phone will only ring once before a call goes to voicemail. Seems like there may be a delay in the call coming through. I generally have a good Wi-Fi connection, but like any Wi-Fi connection, it can come in and out occasionally.
I want to avoid a factory data reset as well.
I have the same problem Essential on Sprint
I am also experiencing this since the 8.1 upgrade, 8n T-mobile. Multiple networks that had WiFi calling pre-update are no longer functioning on either of our phones(wife and I both have them). I often work in a basement, so this is an important function for me.

Wifi calling not working.

I received a new pixel 4a 5g on Friday. I have spectrum mobile and I can't get wifi calling to work. I have called spectrum twice and have gone to the local spectrum store. I have also chatted with a Google tech. No one can get it to work.
No issues with WiFi calling. Have you tried switching to airplane mode and re-eanable Wifi only? This switches on Wifi calling quickly on my 3a and 4a5g

I also have a 4a 5g phone that I've been trying like hell to get working. Started with just seeing if I could find it myself. Found something in the settings (gone now), but it said something about WiFi calling. It happened to be grayed out.
Next step was calling tech support. They could help me and they convinced me that I have to change the sim card. OK change the sim card for using wifi calling. Whatever, the sim card arrived today and I swapped it out. Now I don't have phone service and I still can't get wifi calling.
My question is where is the setting for turning wifi calling off and on? I follow these directions;
How to Enable WiFi Calling on Android 11 Stock OS
Step 1: Pull down the notification panel at the top and touch the “Settings gear (Cog)” icon.
Step 2: Touch on “Network and internet”.
Step 3: Touch “Mobile network”.
Step 4: Scroll down and touch on “Advanced”.
Step 5: Tap on “Wi-Fi calling” in the calling section.
I follow the steps and it states my wifi calling is on. Yet when I call, it's is calling tech support. I've spent way too much time with dodgy tech support. Not sure what I can try at this point. Fortunately I have other telephone options, but not my main.
Any help would be greatly appreciated.
Us3r_1,
I followed your steps 1-5 on my 4a5G and on T-Mobile and Vodafone it works for me.​

Sorry for the confusion here. and thanks for the reply. OK it shows that my wifi calling is on, I don't have any phone service at the moment. Regardless of what number I call, it goes to the step through for getting to different options, like activate phone, change number, and so on. It seems like I have to turn off the phone connection to get wifi calling to step in. BTW, this SafeNet which I think they use Tracpone.
EDIT: My service is not SafeNet, nor SafeLink, but is Net10 on Tracpone. Not for long though.
You're welcome.
BTW: On my 3a I had to restart the phone from time to time. Perhaps this helps in your case.
Double check with your provider that WiFi is switched on for your account.
Yeah I reboot several times through all this. Just did now too. I did see an option to preference wifi calling over phone service. I did that and still it goes to stepping through to options in the phone service when I try to make a call.
You could try switching to airplane mode and then enable wifi only. Keep airplane mode, don't switch it off. Try calling then. This forces Wifi calling.
Finally got the option and my phone working. You are not going to believe what the problem was. It ended up that the service, BTW the service is Net10 Wireless, anyways they had the old sim card number on my account and they were using the the old number! The directions on the new sim card sent, stated to put the new card in the phone and call the number provided, which I did. I gave them the new sim card number and I assumed everyone was working with the new sim card. After well over 6 hrs with "tech support", some with a roster clearly calling out in the background. At the end I was demanding upper management right when I contacted someone. Finally had this tech support go through all the records and she figured out the sim card number was screwed up with the parties.
I'm pissed, it shouldn't take over 6 hrs and 2 days to get this resolved. I pointed out that this was the stupidity of "tech support" that caused practically this whole delay and I would say this people started the whole thing! I called up to get wifi calling up and running. The "tech support" stated that I need a new sim card. Which was the start of this mess. More than 23 calls to them regarding this!
In the end, I put the old sim card in and everything works! Even wifi calling works!
Great!

Sure would like to learn and know how and why the sim card plays a roll when you are trying to get wifi calling working. In my simple world, it's a working unlocked phone, a wifi connection, and the software on your phone to get this working.
Holly crap! Been using wifi calling successfully for the last day. OK so now I want to go back to regular phone service with phone providers. And you would think you could follow the steps at #7 and stumble your way to getting regular phone service, right. Nope, following the steps laid out will not do the trick. Now I got to figure out how to do it.
Any help on this? The Mobile Network option in Network & Internet is grayed out. Also the + sign does nothing. Turning off Wi-Fi does nothing to.
(Hoping the Hotspot & tethering is easier than wifi calling. I'll be in trouble if it's not.)
i don't have wifi calling on this phone but do on my note 10 plus,is it just in usa?

All I had to do was enabling Wifi-Calling in my phone and call the phone company to enable Wifi-Calling.
As soon as I am out of reach of my Wifi, it switches automatically to GSM or LTE (my contract does not provide me with 5G).
In other words: No need to change any settings.
Same if I disable Wifi manually. The phone shows LTE the same second.
