Dual Sim P20 activation, any tips please ? - Huawei P20 Pro Questions & Answers

Hi , have bough the dual sim tray, but need help to make my Phone dual sim if anyone knows how to alter the system to recognise a second sim ?
Sorry if this has been asked before, am new here
cheers

Two words: Funky Huawei.

Beware.
I have rebranded and then changed over to dual SIM using funky Huawei. I was left with a fully functional dual SIM and broken speaker sound volume. It was stuck at 20% and no matter how many resets I did could not get it fixed.
You also loose bootloader unlock using Funky Huawei. I luckily had my phone replaced under warranty...

The only way is to use the funky Huawei method. You must pay for it. Go to Funkey Huawei site and you have all the info. These is also a thread here in XDA.
I changed my CLT-L09 single-sim in a CLT-L29 dual sim in april-2018.
No problem at all. I have a dual-sim phone and all goes well. Also I have had all the OTA update from Huawei.
The only problem is that you can't root the phone anymore, even if you buy the unlock code from a site. This because Funkey change the bootloader code to enable the dual-sim code, and there is no unlock code that works.

[Q] Official operator unlock code not working - ideas?

Last year, I got an HTC Incredible S and absolutely love the phone. The only thing I did not like was the capacity, so I got a 32GB card instead. I do not know if there is a special procedure to follow when you change the SD card, so I just copied everything from one card to the other. Of course, some programs did not find the data, so that data had to get loaded again.
The phone was locked to an operator in Norway - Telenor, but as I used a SIM from an operator that used their network, I did not need to switch. This year I needed to go back to Brazil and wanted to make sure I could use my phone with my TIM number here. So I called Telenor when it was getting close and got the unlock code. I then tried to unlock it after changing to a SIM from a different network in Norway. But it did not work.
After trying a third SIM card, it seemed to work, so I thought it was ok and the phone had never actually been locked. How wrong was I...
After arriving in Brazil last week and picking up my SIM from TIM Brazil, I found out that the lock is very much in place. And the code I got is not working.
If I was in Norway still, I could send it to Telenor for free and they would fix it, but I am not. So what can I do to unlock it?
The full model as displayed by the phone:
HTC Incredible S S710e
The instructions for unlocking never mentioned anything about keeping the original SD card, but can that be the reason for it not working?
After I changed to the new SD card, the cold boot of the phone is extremely long, but most of the day-to-day operations is ok.
Any suggestions to what I can do to remove the operator lock? I have noticed that there is an official site from HTC where you can unlock some things of the Incredible S. Will that do the job?
I really need to be able to use my phone here. I hope someone out there have an idea what to do.

No the unlock procedure at HTCDEv.com is to unlock the bootloader so you can root and customize your phone. Unfortunately, rooting your phone will not help ou SIM unlock your phone.
You need to SIM unlock your phone which the unlock code should have done. Also the SiM unlock code has nothing to do with your SD card.
You need to contact Telenor and tell them that the unlock code does not work. Or you can try one of the paid services that provide unlock codes for a fee.

Can't imagine it not working, if there is two sim slots in the little drawer, I would assume it'd work....
Maybe it is some sort of software error. Have you tried a factory reset and see if it works after that?
Does vodafone in any way make any changes to the stock firmware (apart for maybe adding some customized Vodafone bloatware...)?

My money is on the firmware not supporting Dual Sim. Most carriers hate the idea of Dual Sim as its in there interest to prevent you using anyone else's sim apart from the sim they sold you with the phone. :crying:

Exynos Note 8 models are (probably) all dual SIM hardware - see pic

Just to put to rest the rumor that the hardware is different, here is a picture of the SIM/SD slot on my N950N (Korean single SIM model), which you can clearly see both SIM slot pins, as well as the SD pins.
Mind you the single SIM models only come with one IMEI so I have no idea if you can use one for a dual SIM setup, but the hardware most certainly is the same.
Also, bonus pic showing that this part is apparently labeled for an N95OU which is the north American Snapdragon model. Must be sharing quite a few parts even with those ones eh?
Hi Kalm_Traveler,
I buy a N95OU1 north American Snapdragon model. I buy a dual SIM tray in Amazon. How can I make the 2 SIMs works? It's possible?

That's the thing, as Kalm_Traveler is pointing out, you only have one IMEI. Dual sim phones have 2 IMEIs. How would you obtain a second IMEI to use to use legally? And you would need root access to configure it to work even if you did happen to have a second IMEI to use.

I legally own 3 old phones (Blackberry & other model) where I could easily get valid and, again, perfectly legal IMEI's;
so besides the legal concern, which does not apply in this case, it would be interesting to know if it's possible (or will be) to root the phone and enable somehow its dual sim capability having a 2nd IMEI (owned and legal) available to set up.
If the hardware is really the same we have just to wait, maybe

Try changing this line in build.prop and see what happens.
ro.multisim.simslotcount=1
To
ro.multisim.simslotcount=2

On my Note8 monosim brand HUI Italia and rebrand Vodafone Italia in build.prop have already line ro.multisim.simslotcount=2 but not have any menu for dualsim. My phone not have root access.
To make the menus appear, do you need the dualsim cart?

On my N950U1 (Snapdragon US Samsung unlocked, non-dual SIM), using Shortcut Master app, I found the working dual sim menu. See attached ss.
So also SD Notes could be dual sim capable.

Can you please tell me how to do it? I own the sm-n950f single sim European version.
1. Install Shortcut Master (lite) from Google Play.
2. Select 'app explorer' from menu.
Select 'system apps' from pull down list.
3. Scroll down to and select
'Mobile networks' (com.samsung.networkui),
4. Scroll down to and select
'MobileNetworkSettingsTab' (com.samsung.networkui.MobileNetworkSettingsTab)
5. Press 'Launch'
I have not been able to actually test whether 2nd slot works, as I am waiting on delivery of dual-SIM tray...
I don't think it has the software to work - you would need to have some way to add Stk2, and more importantly the libsec-ril-dsds.so libraries.
Your probably right, but will see what happens when $3 tray arrives ...

Thank you so much for your help! Did you flash the dual sim rom yet ? I have also read at the forum that it actually works but we need to change some files with the similar of the dual version. (https://forum.xda-developers.com/galaxy-note-8/help/galaxy-note-8-n950f-modding-dual-sim-t3685255) May i ask where did you get the dual sim tray from? Here in Greece it's unavailable. Thanks again and i hope everything goes well!
I did not flash anything yet... As I have SD, will /can not root easily..
Just search 'SIM tray Note 8' on Ebay...
Ok i have already subscribed to this subject so if you receive the tray and you make the dual sim work please write something here so that I will try it also to my device. (please forgive my English)
Thanks again for your support and best wishes to you for 2018!
wonder if you can just flash the duos firmware without root if you have the OEM unlock option available and get a dual sim tray?

same on my unlocked exynos model
ok, scratch my first question, firmware is the same for both Single and Duos anyway.
I have a second dual sim tray coming in the post and also have an old Samsung phone I can use imei number from to be legit so will take it from there, once I set up my dual sim I don't think I'll mind rooting this single sim as you still get OTA as long as you don't install custom Rom
just did a quick check here in case it helps anyone...
took the tray out of my dual sim to stick into my single sim Note, dual tray won't go in unless I put a sim into slot one so did that with an old inactive one and put my own sim into tray 2, rebooted just for the sake of it, can still make and take calls etc... but looking at sim info in settings... about phone... it showed sim as inactive and no mac address, I'll try with 2 active Sims when I get my hands on one over the next days.
Hopefully any small info gathered can help determine how easy/hard it will be to get dual sim out of single sim
@Kalm_Traveler looks like you'll need to add dual sim capabilities to your zip once you get wifi calling working xD
On the N950F, could it perhaps be as simple as installing a dual SIM tray and then flashing the N950FD firmware? Or just editing some files on the current firmware.
Maybe the second IMEI will come from the hardware?

Single SIM to dual SIM

Hey guys,
This is sort of an odd question but I thought it would be worth asking anyway.
I recently bought this phone but then realised it's the single SIM variant. At the time of purchase I didn't appreciate there were two versions. I mean, even the manual says you can put a second SIM instead of the memory card.
Anyway as you can imagine this is very annoying because the shop won't take the phone back "just because". So I looked on eBay and I can buy the dual SIM variant SIM tray.
Do you think I can just replace the single SIM tray with the dual SIM tray and use two SIM cards like a champ? I guess the OS wouldn't recognise the second SIM, would it?
I'd be grateful if someone could shed some light on this issue and let me know what my options are (if any).
Cheers
I mean that is impossible, but you can try to ask a question to Nokia support, maybe

I think it's not possible, dual sims are being flashed with a different firmware version from HMD. Let us know.
Differeent rom flashed? Ok but then this must be because of the second imei that got to be written somewhere in a flash partition. Would the Android os-code be really that different?
I think it would not be possible not because of the different firmware or missing imei2 but because of a possibly missing sim2 slot connection
Check attached pictures of the different sim trays attached and an inside view of the sim slot!

The second IMEI exists!
Trying to type the code *#06# I've found two IMEI number for my TA-1004.
In Settings -> Network menĂ¹, there is SIM Cards section
The only test to do is to buy the dual sim tray and check if it works.

OP has single sim TA-1012.....

dual sim

Is there anyway I can mod the phone to accept dual sim
The mates are able to do this, buy flashing l29 software and adding a dual SIM tray
Hey mate. Yeah you can but you risk killing your speaker volume. I used funky Huawei to enable dual SIM on my P20 and it worked but my speaker volume got stuck to about 10% and no amount of firmware reflash did anything. I had to get it replaced under warranty. Also your bootloader will be locked.
Thanks
