Hi! 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
and resolve any carrier related issues that you want to address.



First, I will share my personal experience with my unit using my Globe 5G enabled postpaid sim. My N20U 5G unit is from Hongkong with TGY (Hongkong) CSC.
While on TGY, 4G CA and 5G on my unit were NOT working. I am only getting max 20mbps with 4G and not getting the 4G+ signal.
Note: To check the existing CSC, go to settings > about phone > software info >service provider SW ver. You should see something like TGY/TGY,TGY/TGY.

However, I was able to change my CSC from TGY to BRI (Taiwan's CSC) using the procedures in this thread.
I am now on BRI and I am glad that 4G CA is now working. I am already getting 70-125mbps on speedtest with it. Check this post on how to check 4G CA.

However, I have not tested the 5G signal yet as I am far from a 5G enabled location.
It's noteworthy though that Taiwan telcos use 5G bands n78, n257 and LTE DSS which include that n78 5G band being used by telcos in the Philippines (source: List of 5G NR networks
)
I am hoping for fellows to hit this thread try this change and test if this will work on his/her network, hopefully on 5G network too.



UPDATES/SOLUTIONS

How to access ServiceMode menu on pre-OneUI 3.0
1. Install Google Phone app from Play Store and set it as default dialer.
2. Open Google Phone app and key in *#*#27663368378#*#*


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.

Go to UE SETTING&INFO -> SETTING -> PROTOCOL -> NR5G -> NR5G SA/NSA Mode Control > SA/NSA ENABLE Exit


Solution to make 5G work in PH (also works in some countries with compatible 5G bands)
Try this. On UE Settings>Protocol>GCF>Remove NR Whitelisting. Then reboot. That's the first step I did.

Unhide/Enable 5GNR bands 3 and 28
Hi there,
Please go to [2] UE Settings >> [2]System
On the last page choose [1] SET LTE BAND CONFIG
Then click on [1] SET DEFAULT LTE BAND
Reboot your phone and check again the available NR bands.


How to check what 5G bands are enabled
4. Go to UE SETTING&INFO -> SETTING -> PROTOCOL -> NAS -> NETWORK CONTROL -> BAND SELECTION -> BAND SELECTION SIM * -> NR5G Band Preference -> (enabled ones are marked with asterisks)

If not yet enabled, select each then -> GO MAIN -> APPLY BAND CONFIGURATION. Exit then reboot

Better 4G Carrier Aggregation (4G+)

The following are the mobile 5G bands being used in the Philippines from foi.gov.ph:

- Smart: 1, 3, 5, 8, 40, 41 and 78
Update: According to this article in smart website, they are using NR28, NR41 and NR78 with 5G CA.

- Globe: 1, 3, 8, 28, 40, 41
Update: According to Globe's website, they are using NR41 and NR78

METHODS FOR ONEUI4.0

Here 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.

Update: This stopped working after a certain update.
Fix 5G Reception

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.
Don't know which worked, just sharing.

Hi! I am planning on buying HK Variant of N20 Ultra 5G. I see that the 5G capability is not automatically integrated with PH couriers with this version. I am not that quite experienced in playing around with ROMs. May I just ask if the procedures you mentioned require rooting? :(

Hello mga Kababayan!

Glad to meet you here. Just an update on my case. I am back on TGY and 4G c.a. is working fine now on my unit with the latest update. I still don't have a chance to test 5G as there's no 5G here in our province.

But for those interested, here's the ff new hopefully useful info that I read somewhere.

The 5GNR bands missing is in N9860 are 5, 8, 34 and 40. Theoretically, our device should work in 5G sites utilizing 5GNR bands 1, 3, 28, 41 and 78 which our device is capable of. Otherwise, 5G will not work.



However, there are config issues that possibly keep our device from working on our country's 5G.
- 5G Stand Alone (SA) mode is disabled by default in our device. But there's a way to enable it.
- 5GNR band 28 in TGY and 5GNR bands 3 and 28 in BRI are disabled by default. But there's a way to enable it.

To enable 5G Stand Alone Mode:
1. Install Google Phone app from Play Store and set it as default dialer.
2. Open Google Phone app and key in *#*#27663368378#*#*
3. Go to UE SETTING&INFO -> SETTING -> PROTOCOL -> NR5G -> NR5G SA/NSA Mode Control > SA/NSA ENABLE Exit then reboot.

The above guides are based on this thread.

Share if you have tested the above and if it does work on your unit or not.


UPDATES:

New method to access ServiceMode in Android 11 in this post.

Finally a working solution to Enable 5G - Huge thanks to @xUtsumi for discovering and sharing this solution.

Try this. On UE Settings>Protocol>GCF>Remove NR Whitelisting. Then reboot. That's the first step I did.

I’m in the same situation as this guy. Additionally, @tribalfs , when you said the latest update, did you mean the 3.0 update?

Try to do the following to force refresh 5GNR band list, you can revert settings after to sub6.

UE SETTING&INFO -> SETTING -> PROTOCOL -> NR5G -> NR5G sub6/mmWave > ALL ENABLE then reboot

After that, redo step 3 above.

    I recently got an eSim for my Globe postpaid and for some reason I can now get a 5G signal even if I don't have n78.

    I think you're connected to NR41 - which I believe is the more widely used 5G band by Globe specially on NSA mode.
    You can check the connected band(s) using the *#0011# code.

    Try this. On UE Settings>Protocol>GCF>Remove NR Whitelisting. Then reboot. That's the first step I did.

    Huge thank you to your both. :)(y):D:p:p:cool:

    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
    It was a consolidated effort. :) 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. :D

    5G working on mine with oneui4.0. 5G is new on my location, just saw this now. And I am a bit surprise that I have it on my device. Although I changed some EFS files on my device using QPST few days agoI'll share soon.

    What does deleting the entire L2 directory do?

    If delete L2 directory with QPST tool

    Removed NR Whitelisting in GCF?

    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.
    Don't know which worked, just sharing.

    You can check the enabled bands on your phone using this
