No, Korean model (N) is single sim, i need to know if there is a possibility to convert in dualsim.
In the setting menu sim card manager is not available
Thanks

There is no way the 998u doesn't take the 998uB software,

The SM-G998N does not support e-Sim, it can't be activated.

How to Sim Unlock HTC One 802d Cdma-GSM?? Need help urgently

Hi guys,
I'm from indonesia, I bought HTC 802d in china last week. Before buying, i asked the sales person specifically if both the CDMA and GSM are unlocked. They said yes they are unlocked. I only brought my roaming GSM card and it worked just fine. Didnt bring my CDMA sim.
Came back to jakarta, put in CDMA sim and it said no service. FYI, i checked the cdma freq between indonesia and china, and they share the same frequency. So, i guess that the Sim 1 CDMA slot is being carrier locked by China Telecom.
I had followed all the intructions thats available in XDA, from unlocking bootloader, flashing recovery found on chinese web, installing ROM from chinese web, got my blinkfeed working in english, facebook & twitter also worked. Even perform S-Off using moonshine.
However, the sim1 slot is still showing "No Service".
Please help me with your expert advice. I need to get the CDMA working as soon as possible as the GSM part is only running on 2G and its internet is sooooooooo slowwwwwww....:crying::crying::crying::crying:
Thank your for your time and attention
No body have any idea?

I doubt I can help, here in the USA the CDMA is never locked and doesn't use a SIM card. On this side of the pond, only GSM uses a sim card. The CDMA phones that have a sim card here, is because the 4G LTE technology is a GSM, so their sim card is for LTE only.

Actually the above worked for me. After rooting and editing the build.prop the phone can connect to a CDMA network in Indonesia just fine. The only eyesore is that the carrier name doesn't show, it only shows its carrier code.

I'm in China at the moment and ended up picking up one of these today (HTC DESIRE 609d) which i was told was unlocked. 1 Sim card however seems to be locked to china telecom.
You managed to remove the lock? So I need to find a special DEV rom? if so could you please send me a link or point me in the right direction? Im a bit of a noob...
Cheers, Phil.
Hi guys! I also unlocked 1-st slot but it works only GSM card. my cdma R-UIM not work for this slot. Befor unlocking first slot I edited device nam settiongs with DFS. When I put GSM card to slot one and select cdma mode, phone use setting from device and pick up signal. but not incoming and outgoing calls (because there is no registered number to carrier). But in the DFS I choose "Only R-UIM" but phone not read the R-uim card. How can I unlock first slot to use my carrier R-uim card. (my carrier PerfectumMobile-Uzbekistan)

That's not really how it works.
Different variations have support for different frequencies, you can't change that.
Also, if it's SIM locked, you'll still need to SIM unlock it.

P8 Lite 2017 Unlock Dual SIM (PRA-LX1C33B120)

Hi Guys,
I have P8 Lite 2017 (PRA-LX1C33B120) and I want to unlock the second SIM slot.
How can I do it?
I already have the phone rooted, unlocked and with TWRP flashed.
I just don't know what is the right firmware to flash.
I've tried some through DLOAD but it just doesn't work.
Can you please help?
Thx
Be very careful with flashing firmwares, a lot of people bricked phones and this one is complicated to restore.

I know... I was reading the other threads. That's why I'm asking help for the build I have.
It seems too complicated, but I really need the second SIM slot.

Have you pursued the device already with two sim?
Maybe you have the Single Sim version.

I do have the single SIM version, but it's possible to activate the second slot by changing the firmware.
The question is, I don't know what firmware to use.

I can tell you that PRA-LX1C432B110 is dual sim firmware, for unlocked EU PRA-LX1. But i don't know if you can just flash it or what are the steps to activate dual sim.

Yeah. That's it.
But I'm afraid to brick the phone.
I only have this one .
Your Phone has an IMEI. For Dualsim you need two. This cannot function. Wait for the next OTA update. If then afterwards only one Sim is active, your device is also laid out technically only for Sim.
Still can operate with one IMEI, did the same with Mate 9 single to dual, both sims working superb.

And it's possible in this one aswell, but I don't have the right steps to do it in my model and firmware biuld.

N9600 Dual Sim flash CSC without root

Since the N9600D is a Snapdragon device, would it be possible to flash canadian firmware for the 960w on the phone using ODIN without root? I am looking to install a Canadian CSC. Would it work and would I lose dual sim functionality?
There is no root

that could help but it needs to connect to the phone via usb (last time i used octoplus was 7-8 years ago)- there might be a usb service to connect through internet but i dont know how safe is that.

No it won't work unless first you have to clone main imei via chimera tool or any other tool that help to colne imei and you have to buy dual sim tray also.
After that dr.keten rom will work as dual sim.
There are many video on YouTube how to clone imei for dual sim.

Hey, luckily it works for me as I have already. I flashed Stock android Q using odin and there was only 1 imei at that time, and after flashing Dr.Ketan's rom I have 2 imei and dual sim capability . And ofcourse dual sim tray is required.:good:

please can the process of converting N960N to N960F/DS be reversed, and how?
So, flashing the correct firmware for the device restore the phone to it's factory state with software updates available. Dual sim will be lost, (of course). and the device will show the true model as N960N, not N960F/DS
