Any help, please?
Settings - Mobile Network - Right above the Mobile Data Toggle will have a small box (For me it says T-Mobile and my phone number, it's a small slightly darker white box) - Press that. This section is called Sim Info and Settings. This is where they moved Preferred Network Type, APN settings, Roaming, etc. All it did when you updated to 12 was it probably toggled 4G/LTE and turned off 5G. I keep mine on 5G On.
This should solve your issue

So I've confirmed today that there is in fact an LTE issue with the Galaxy S4 Google Play Edition, and thankfully, it's software based. Hopefully, Google and/or Samsung implement a fix in short order. In the meantime, here's the cause (so that you can prevent the issue), and here's the workaround (so that you can correct the issue if you're affected).
Background:
Comparing the Google Play Edition to the Touchwiz Edition, there is a setting that is slightly different on both phones. If you go to Settings --> Wireless & Networks --> More --> Mobile Networks --> , you will see a setting; either "Use only 2G networks/saves battery (GPE)," or "Network Mode (TW)."
The Network Mode on Touchwiz allows you to toggle between available network modes based on carrier, usually 3 individual settings and a full Automatic setting. The 2G Networks setting on the Google Play Edition is the cause for concern here. It's directly ported from the Nexus 4, and here's where the problem lies.
Cause:
While both devices have numerous hidden network modes, the toggle only allows for you to switch between two modes; GSM Only, and WCDMA Preferred. GSM Only occurs when the box is ticked. This sets you on Edge-only for battery savings. WCDMA preferred tells the phone to look for GSM/UMTS (Edge/3G/H), but to prefer the latter if both are available, even if the latter has a weaker signal. Did you see LTE in the equation? If you noticed that it's absent, here's why.
The S4 has an additional mode; LTE/GSM (Auto PERL). This sells the phone to switch between LTE/H/3G/Edge based on signal strength and T-Mobile's/AT&T's APN settings and roaming list. The S4 GPE comes with this mode on by default. If you tick the 2G box, you'll go to Edge only. If you untick the box, instead of going back to LTE/GSM, you are sent to WCDMA Preferred. Now, you're stuck between 2G/3G/H, or 2G only. LTE is gone. Nice oversight by Google/Samsung
The "Fix":
Because this is an issue with the firmware, there is no permanent fix. However, there are easy user-facing applications that will allow you to toggle LTE back on. The one I'm using is LTE Setting (Google Play Link). From the main page, go down about 2/3s of the way and you'll see a drop-down menu. Select "LTE/GSM (Auto PERL)" to restore LTE. Now, the next time that you set your phone to 2G Only for the sake of battery savings, you'll need to use this app again to restore LTE compatibility.
I've enclosed two pictures. The first is the setting as it appears in the Google Play Edition. The second is as it appears in a Touchwiz model, and why the Touchwiz variant does not have this problem.
i had this problem when i have flashed 3 various roms so i have to flash back a rooted stock rom which you can find in this forum (in my case XXUBMGA). after flashing i checked Settings --> More (under wireless) -->Mobile Networks and there shoud be 4 choices 1. LTE/WCDMA/GSM (auto connect) 2. WCDMA/GSM (auto connect) 3. WCDMA only and 4. GSM only. i checked no.1 to see if it worked (after rebooting). then there was no 4G connection on the status bar, so i begin to search for the answer in this forum also. here's a list of what i did to solve my problem.
1. i asked my carrier for an LTE capable SIM (micro SIM)
2. i see to it that there is an LTE coverage in my area for testing
3. LTE is activated in my prepaid account which is separate from internet access.
4. (optional) in settings/more/mobile networks/networks operators i selected manual because it drained my load when my network is not available when connection to LTE coverage of another network.
5. asked from carrier the correct APN
of all the listed steps i made above, it was the SIM card that was at fault, because my carrier gave me a normal sim but was just cut to a micro sim so i insist to have a pre manufactured micro sim. you can google for answers but i don't think this is a bug. i have read plenty of lte issues during my search and all point to coverage, SIM card and requesting the carrier for an LTE activation on your account.
hope this helps
I've edited the original post for clarity. I apologize for any confusion that I have caused.
Bug has been submitted to and acknowledged by Google. It's evident in the latest 4.3 leak, so no idea if the fix makes it into the final push, or a subsequent update.
Bug has been fixed as of last night's OTA to 4.3.
Enable WiFi Calling & VoLTE on T-Mobile US onOP 5 w Original OxygenOS 4.5.5 Firmware
Hi Everyone,
Just wanted to let you know that I was able to enable Wi-Fi Calling and VoLTE on T-Mobile US on OP 5 with the original OxygenOS 4.5.5 firmware by doing the following:
1.) Ignore for a moment that you are already on T-Mobile. This was preselected for you automatically by the virtue of inserting a T-Mobile SIM card.
2.) Go to settings and manually search for/select mobile network. Let the phone search for a mobile network for you.
3.) You will get T-Mobile to appear but the only connection choices you will be given are 2G, 3G and 4G. There will be no choice to select 4GLTE.
4.) Ignore the fact in 3.) and proceed to select the "plain" 4G option
5.) Go back to SIM & Network Settings. The preferred network type for you will appear to be 2G/3G/4G (automatic).
6.) The WiFi Calling and VoLTE options now appear on right under the Preferred network type. Select WiFi calling/or VoLTE
7.) Switch to WiFi. You will get a notification on the top right bar that you are on WiFi/VoLTE calling.
8.) Try it out - it works
9.) Now turn off WiFi. This will switch you to your T-Mobile network.
7.) Check your notification bar on top, it will show that you are on 4G LTE.
8.) Test your 4GLTE connection speed with a program like speedtest.net.
9.) Mine was ~ 55 mbps download and 12.4 Mbps upload - definitely 4GLTE speeds.
10.) Enjoy

You don't need to go thru any dance on this...my phone has always done this with out changing any thing... T-Mobile in Atlanta..
On my OP 5, VoLTE and VoWifi did work instantly.
All of this was enabled without any effort for me on TMobile.
I am curious though, are you saying that 4G (by itself) is an option for you on preferred network type?

Many retail/unlock mobiles have "Wifi Calling" function but not any menu entry to enable , The APP can check the hidden function and enable it if can use.

Agreed, was immediately able to run on both wifi and T-Mobile LTE once the SIM card was inserted.

I followed the steps, but VOLte and WiFi calling even is not working. Furthermore the options are not displayed.
T-Mobile Germany.
My old Samsung S7 EDGE working fine with VOLte and WiFi calling at the same SIM card.
Is there any fix for this on my OP5?
Hi all,
First time playing with dual SIM ad think Im missing something easy here.
I use GiffGaff (£5/m) and barely ever use data. Saw an offer from Voxi (Vodafone) for a 6GB data SIM. Grabbed one thinking I could use it as a second SIM just for data so I have a constant connection and a SIM I can move between devices where needed (MiFI, tablet etc, why I went with a second SIM rather than a different plan on my primary GiffGaff SIM)
Put the Voxi SIM in my Redmi, setup the APN and was greeted by the 4G symbol with the cross in the lower corner (no network connection but calls and texts work)
Now this is where Im getting confused. From what I can gather, only one SIM can be 4G while the other SIM will drop to 2G.
How do I go about setting this up correctly?
I do not need 4G speeds on the Voxi SIM as I only really need a constant connection, just enough to ping a few emails and Whataspp/Telegrams around.
Both GiffGaff and Voxi/Voda support 2G and would prefer the 4G to stay with GiffGaff for call quality.
So, I have:
GG in slot 1 (4G)
Voxi in slot 2.
APN set for Voxi.
Voxi set for Mobile Data
How do I now tell the Voxi SIM to connect over 2G and not 4G?
If I switch mobile data to the GiffGaff SIM, the 4G symbol from the Voxi symbol disappears so it must have switched to 2G but then GG is on data (with 4G sysmbol). When I switch back to Voxi GiffGaff goes to the no 4G but Voxi has the 4G with cross.
Is anyone here using dual SIMS like this in the UK?
Settings -> Network & Internet -> Mobile network -> Advanced -> Preferred network type
Did you try that?
Just tried every setting, in-between each one I toggled the mobile data switch and tried a ping and a Chrome page refresh

Some things to note, I dont know if these are bugs in the ROM/AOSP or normal:
SIM Cards:
SIM Slot 1 shows "giffgaff - myphonenumber" and when clicked shows 'Operator - giffgaff' & 'Number - myphonenumber'
SIM Slot 2 shows "Voxi" - blank" (I edited the name to say Voxi manually) and when clicked shows 'Operator - unknown' & 'Number - unknown'
Mobile Network:
Enhanced 4G LTE Mode - This toggles the settings for both the GiffGaff and Voxi SIM regardless of within which SIM I set it
(Just found a reference to it here but no reply so dont know if this normal?)
This applies to the actual network in these settings as well. GiffGaff shows: Network - O2-UK, flicking across to the Voxi side it also shows O2-UK even if I untick 'Automatically select network' and search manually, choose Vodafone UK (Successfully registers on network) but doesn't change to 'vodafone uk'. The main sub heading under 'Settings - Mobile Network' shows O2-UK as well the status bar carrier info has always shown both giffgaff and vodafone uk no matter what.
These change if I completely disable SIM1 though, then it shows vodafone. I presume this is all because SIM1 is 'Priority' though. Doesnt help when troubleshooting
Also I realized I forgot to mention the ROM is ResRemix, not stock (oversight on my part, haven't used a stock ROM on a device for years, forgot they exist )
I have also tried the SIM in my old Nexus 4 and it worked with no issue so I am assuming it is definitely a device issue rather then a SIM/Carrier one.
Im going to try another ROM over the weekend, probably Lineage, If I get chance to try and get a baseline to see if this is ROM related though (although the ROM thread, people are saying dual SIM is working, mainly the JiO network(?))
Its also harder to troubleshoot when Ive never used Dual SIM before and have no idea how thongs should look and feel etc
Just acquired an Essential Phone. Had a LG G5 (H830) and now I own a PH-1. Well every time I want to use the Video Calling feature the call drops. I get the LTE+ icon with full bar on the status bar, however once in a while the signal appears to become weak. I have both the "Enhanced 4G LTE Mode" and "Carrier video calling" turned on. It used to work with the LG G5 but now it's just frustrating not to be able to use this feature anymore. Anyone else having this problem? PH-1 is running Android 9. Am I missing anything?
I contacted the Essential support team to which they replied the following:
"If you are accessing Video Calling through the dialer, this would be an advanced carrier service and your carrier would be the best point of contact for troubleshooting if it is not working correctly.
Other than the toggle for enabling this feature (under Settings > Network & Internet > Mobile Network > Advanced >Carrier Video Calling) there are no other settings that would control this feature, and the routing for the data traffic is handled by the carrier.
From the help page for this service on T-Mobile and MetroPCS, they both list that Voice over LTE (VoLTE or Enhanced 4G LTE Mode) needs to be enabled if you are connected to LTE, and Wi-Fi Calling needs to be enabled if connected to WiFi. Both of the settings are also found under the Mobile Network > Advanced link provided above in Settings, so that might be a quick thing to check.
It is also possible that basic troubleshooting for cellular connections might help with the issue that you have noticed. Sometimes just rebooting can help fix odd network issues as you grab a fresh connection with the network, and we also have the option of resetting your network settings. This will restore all network settings to factory defaults, and might correct what you have noticed."
Thanks for your help guys
I bought a brand new factory unlocked Galaxy S10+. I popped in my Tmobile sim card but my calls goes to voice mail and I can't make any calls in following conditions.
I also tried Verizon sim and it acts the same way so not sure if network is the culprit.
1) When the wifi is on, my phone identifies network as I see 'Tmobile' in screen, signal strength is '-113 dBm 0 asu' but no actual incoming/outgoing call.
2) When the wifi is off, but screen is locked for 3-4 min, I still see 'T-mobile' but no incoming/outgoing call. Also, the service state changes 'In service' to 'Out of service' intermittently where I have to toggle aeroplane mode.
So, I have to toggle aeroplane mode on/off to get the network back while wifi is off, signal strength is '-81 dBm 59 asu' then everything works normally until I lock the screen as in step 2 or use wifi as in step 1.
This is my second replacement phone and it is behaving the same way as the first one. So, I am not sure if I am having bad luck with Samsung phones or if something is funky with my network. I also have a S9+ which has no issues at all with same sim cards and network coverage is excellent in my area.
Any idea or suggestion would be really helpful. Not sure if I should just change the firmware from U1 to Tmobile or something.
I would check your APN settings to verify that they are correct. I am on T-Mobile network with U1 firmware and have no issues with calls (I'm on MintSim which uses the T-Mobile network) but when I popped in my SIM no T-Mobile APN settings autopopulated--I had to enter the APN settings manually.
You should also make sure Volte is enabled in the network settings and WiFi Calling is enabled in the dialer settings.

Thank you for your response. My T-mobile APN settings auto populated and looks fine as I have LTE connection. The issue is that the connections keeps dropping and all my calls goes to voicemail in above two scenarios.
If the LTE didn't work at all or if my calls went to voicemail all the time, I would understand that some settings are not setup properly. But it works intermittently. Since, this is the second Galaxy S10+ with same exact issue, I am not sure if there is a issue with device or carrier.
