About the VoLTE/VoWIFI, is this confirmed? Cause I'm facing the same issue. I can't even activate RCS features in the stock messages app. Anyway, to activate VoLTE/VoWIFI, I need to call them? I'm using Smart by the way.

I am using DITO on a BRI firmware too, and I got volte working without rooting my phone. I just followed a video I saw on a facebook post. 5G is not that important to me though.
So I think there is still a way to activate volte on DITO in N9860.

Up for this. If we get VoLTE working for DITO without root then that would be awesome.
Maybe it's adding the following DITO's IMS APN (in addition to internet APN) that makes it work?
DITO IMS APN:
Name: IMS
APN: ims
MCC: 515
MNC: 66
APN type: ims
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
---------------------------
DITO INTERNET APN:
Name: DITO Internet
APN: internet.dito.ph
Update: Confirmed working on TGY and BRI

What about Smart & Globe? What are the APN settings for those? Might try it on my end.
Based on my experience, they are automatically added even on Hongkong version.
On mine, VoLTE and VoWIFI don't work. Even RCS on stock Messages doesn't work. RCS on Google Messages and 5G does work though.
On Globe, it's not automatic - you have to request the telco to activate VoLTE and VoWifi on your sim. It maybe the same for Smart.

This is weird. The VoLTE icon doesn't appear in my status bar, but on google phone, one of my calls had the HD icon in my call history. I searched and found out this only happens when the call is made with VoLTE enabled. So what gives!?
You can confirm It's working if the network stays at LTE while on voice call.
Update: I bought a DITO sim and tried. I can confirm that manually adding this IMS APN in addition to the internet APN does enable DITO VoLTE on SM-N9860 Hongkong variant (either TGY or BRI). Call and text work. No root needed.

Not sure why but for S20FE HK, not working for me. Any other settings applied? Also, what's the security patch you have?
No other settings just this and the VoLTe switch in settings. Did it with July sp, now it's on Aug (correction: prev is Jun and current is Jul)

I just tried it again and it's now working, finally. Also, no other settings were changed since when I checked on the APN, I see IMS not listed but VoLTE now working as well. Must be with the Carrier Services update from Google.
Could also be from (network) policy update
Edit: I found out that carrier services is not installed/pre-installed on my SM-N9860.

I applied tweak for 4g+ on n9860 here i Serbia. Symbol still shows 4g (no plus) but Internet looks faster on naked eye. Speeds goes from 20 to 35mbs on speed test. I have also mate 20x 5g which shows 4g plus regularly, but speed is just little better.
Is there any sense to try changing TGY to BRi csc and all that gym, or probably I already got result best possible just by tweak?
Thanks

Hmmm. Interesting. Maybe DITO just pushed network update on towers, and supporting all networks?

8Hi! I created this thread for SM-N9860 HK/TW/CH variant users from Philippines.
The GOAL is to make our units work with our local carriers':
- 4G Carrier Aggregation (4G CA) (i.e. 4G+/LTE-A).
- 5G network

How to access ServiceMode menu on pre-OneUI 3.0
How to access ServiceMode menu on OneUI 3.0/3.1
I just saw a method for opening the menu again for Android 11. I saw this on the US thread.
Just check the code on my N9810 BRI
This method only works on Qualcomm versions
I use *#*#276633683782#*#* on Google phone dialer
and it brings up a service mode screen.
Press [5] RF Test and choose [2] PREF MODE SET
（or other options also works ）
It will show Please use *#2263# for mode set
Then just tap three dots on right top menu and choose back
It will bring you back to the main menu.

Update: This stopped working after a certain update.
The good thing though is that it seems that we do not anymore need to manually remove the NR whitelisting on SM-N9860. 5G now works right out-of-the-box on the latest firmware even after performing factory reset on the device .4
It was a consolidated effort.xUtsumi and kent800129.....Greetings form the UK
Huge thank you to your both.
I had almost givem up with this dam phone. Although it is my wife's , no 5g had stopped me importing one for myself.
In the UK this phone got 5g on networks Vodafone and Three but not on god dam EE which is the biggest UK network.
I am going to link your post in the other thread!
Thankyou Thankyou Thankyou Also the only necessary part on enabling 5G is the first part. I just included the next 2 parts to increase signal strength and diversity stuff. Although I don't understand what they do fully, I've researched a little and enabling them will not hurt battery life while increasing the strength of signal. Correct me if I'm wrong on this. 4Here it is.
Windows PC required.
Preparation
1. Install samsung usb driver from here.
2. Install Qualcomm QPST tool from here.
3. On your phone's stock dialer, dial *#0808#, select RNDIS + DM + MODEM (+ ADB) and click OK. This enables your phone's diagnostic mode needed to access phone's EFS files.
4. Connect your phone to the USB port of your pc.
5. Open QPST Configuration installed on your PC. Go to Active Phone tab and check if your phone already appears. If not yet, do the ff:
- Go to Ports tab and Click on the Add new Port button at the bottom.
- You can see the list of ports. Select the one that says SAMSUNG Mobile USB Serial Port. If more than one appears, you can add them both. But It's usually the COM5 port.
- Once you select this you can see the Active Phone tab the connected phone. There should be non-zero ESN value on the correct port.
6. Go to Start Clients menu and click EFS Explorer. Select the correct port and click Ok. Wait for EFS Explorer to finish loading.
7. Once loaded, ensure that Exclusive Access is checked under Phone menu.
Removing 4G Carrier Aggregation (CA) pruning/limitation to improve 4G+detection
- In EFS Explorer, navigate to nv/ item_files/modem/lte/rrc/cap and delete prune_ca_combos and prune_ca_combos_Subscription01 files.
Info: These 2 files limits the 4G CA that our device can do. The 2nd file is for SIM2. Some of our telcos 4G CA combinations are not included in these files. Deleting them removes the limitation.
Other stuff you can do:
Remove 5G CA pruning/limitation
- In EFS Explorer, navigate to /nv/item_files/modem/nr5g/RRC/ and delete cap_prune and cap_prune_Subscription01 files.
Enabling VoNR guide here
(but I am not sure if our telco here already implemented VoNR. This is similar to VoLTE but for 5G)
Some guides and tweaks using QPST for qualcomm modems can be found in https://band.radio/
Hope we can find out how to remove GCF NR whiltelist soon.4
L2 are config files for layer 2 of 5G protocol stack. The other directories are a ML1 (for layer 1) and RRC (for layer 3, which contains the CA control files for 5G. ). Think of them as rules implemented by samsung. Other files that I changed using QPST are the ff for those interested (use Copy data file from PC):
IMPORTANT: Always backup the original files that you will be replacing or deleting.
- carrier_policy.xml and carrier_policy.xml_Subscription01 : added 5G Stand Alone bands for PH telcos. SA bands are disabled by default even if NSA/SA is selected in dev menu.
- policies.xml : updated so that changes on the above files will not reset on sim change.
- lte_feature_restrictions.xml : added PH telcos to the Dynamic Spectrum Share (DSS) network list
- also deleted policyman/persistent_items to refresh the contents
- edit: also deleted cap_prune and cap_prune_Subscription0 files inside nv/item_files/modem/nr5G/RRC (layer 3). This removes defined limitation on 5G CA.
You can check the enabled bands on your phone using this app
