If you're using N950F with single SIM, it's possible to change your phone to dual sim if your phone is non-rooted.

You cannot do this by yourself, there are enough discussions in terms of this,

I have converted my N950F to dual sim and tested, working well on both SIM cards, VoLTE looks only work on SIM1

I'm looking the sim extension cable, I have already bought dual sim slot from ebay, but you CANNOT use sim 2 and SD at same time,

Otherwise you need DIY your SD card and SIM card, I cannot do this because my second SIM card belongs to another country, I cannot get new card if the old one got damaged.

So I'm looking some SIM extender cable.

There are 2 solutions for this,

1. Copy the IXXI to SIM2, some country will restrict same IXXI on the network, duration: approximately 2 hours, remote control 1 time

2. Using 2 different IXXI, but the original IXXI will be lost, they will give you 2 new IXXI for both SIM cards, duration: approximately 3 working day, remote control 2 times

If you need keep the current CSC, please use oreo AP/BL/CP and your home_csc file from your country rom.

I have tested, all good, VoLTE is working well.

If you need change the csc to another csc, normally change to the different csc but in same country, for my case, I have changed my csc from VAU/VAU/VAU to XSA/XSA/VAU.

I'm on vodafone, the VoLTE is still working after CSC changed, so don't if VoLTE is working on XSA with carrier vodafone.

How to change the CSC in same country:

You can just change to another country, then flash your home country firmware back, I have tested, the default csc will be changed to your home csc, even you take your SIM card out.

The only way with unroot is using the combination rom, see steps below (source)

Prerequisite:

*Battery at least 50%,

*Remove SIM & SD Card.

*Important- BACKUP

*Odin 3.13.1

1- Download the latest Combination file,

Google COMBINATION_FA71_N950FXXU3ARA2_CL12771072_QB16471415_REV00_user_mid_noship.tar or COMBINATION_FA71_N950FXXU3ARA5_CL12991683_QB16751804_REV00_user_mid_noship.tar

2- Flash your home country firmware, if you didn't flash to any other firmware, you can ignore this step.

After flashing the official ROM, Do a Factory Wipe.

3- Flash Combination file you downloaded in AP AND your country HOME_CSC file from official ROM

4- After successful flashing is done, wait for the phone to boot up, it will go in to diagnostic/Factory mode, don't panic.

5- Tap Factory IMEI and enter the code *#243203855# ,it will show you list of available CSCs, choose the one you need and tap install (I remembered there is 2 options, I selected the option with full).

6- Just in case, do one more Factory/Cache Wipe.

7- Power off the phone & enter download mode and Flash it with your country's officlal ROM. Four files (BL+AP+CP+CSC) Use CSC, don't use Home_CSC.

8- Knox Zero. System Status: Official

9- You can check your active CSC in recovery mode or use Phoneinfo app.
