I have a SGS5 (SM-G900F) downgraded to Kitkat. (4.4.2)
I can use LTE with one operator A (4G shows in statusbar, speedtest measures above 50Mbits).
I bought a sim for operator B but I cannot switch to LTE mode in Mobile Data Settings -> Mobile Networks -> Network Mode. Any option with LTE is simply not available.
I tested the sim for operator B on an iPhone 6 plus, it works just fine.
I have found some guide for secret codes and walked through it to force LTE. It works, but it does not switch to 3G automatically when I receive a call (it does this with the card of operator A)
So I know that my phone does support both operators frequency bands, I can force it to work, but I want to have the convenience of automatic switching on a phone call.
Is there a list somewhere in the software that has flags for networks to enable and disable LTE options in the menu ? Can I edit this ? Where is it ?
Will updating my Android version fix this ? ( I would really prefer to avoid this, since I use SnoopSnitch )
Operator A is: Vodafone (DE), A1 (AT)
Operator B is: HoT (AT)->MVNO for T-Mobile (AT)
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?
Is there is any fix for this issue
-> I faced this issue in los 15.1 ROM
Every time I need to switch on or off 4g enhanced in mobile networks for making calls
-> 4g enhanced option is common for both sims why?
If I turn it off for one sim . It Automatically gets turn off for other sim
Eg : if you want to call from Jio you need to put 4g enhanced On if not you can't call using Jio . And if you want to call from non Jio ( or 3g Sims or 2g ) you need to turn it off . Then only it is working
Everytime i can't goto settings and change native calling option or turn on/off 4g enhanced and reboot or put on airplane mode and off it for selecting other sim as native calling
Any workaround for this ? If any please provide here. It is much needed one
Hope any developer look in to this issue and fix it as early as possible
Thanks in Advance !!

Hello community,
I have a network connection problem:
No matter with which ROM - except the official Samsung 8.1 - I can not select an LTE mode on SIM slot 1. Although LTE is always preferred in the connection properties, it always stays in H + or EDGE. Even about the * *#*#4636#*#* function and and there "LTE Only" or "LTE / UMTS auto (PRL)" does not work. The mode in SIM1 remains in HSDPA or EDGE. It only switches to the respective mode if I set GSM only or WCDMA only. Then he also changes the net type. LTE does not work here. Although LTE is present - because with the original Sasmung8.1 floor works the conversion - the only error: after a restart is always WCDMA preferred in it.
I can use different Custom ROm (everything formally properly formatted before) - no ROM works.
The 2nd problem: on SIM2 slot no incoming calls go. Call can be accepted, but no sound is heard - but I call with SIM2 everything is as usual without error.
What do you have for tips?
I have 2 SIMs (Both 4G/VoLTE) but none seem to work with Max Pro M2. Is there any issue with VoLTE?
One is from Airtel another from Idea.
I even tried *#*#4636#*#* and forcing LTE but the issue is after reboot the menu changes back to TD-SCDMA/CDMA/UTMS
Mobile Radio Power and VoLTE Provisioned show Green
Voice / Data network type show LTE
In settings Enhanced VoLTE is enabled and Select Network 4G Preferred.
Also as its a Dual SIM phone after dialing *#*#4636#*#* only one SIM shows up in the menu for settings so I have to disable one sim and update setting.
But settings dont stay and keep changing back.
Mobile Operators say that VoLTE is enabled for my number and should work but not working. Any help? Or anyone else facing this issue?
Thanks
For me also airtel volte did not work. Switched to jio where it worked. Cant say about idea.
