dual sim - Huawei P20 Pro Questions & Answers

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

Huawei P7-L10...any chance being dual-sim?

Hi.
Yesterday I bought a P7-L10.
For what I read, it's a single sim phone, but since there are several versions, but some say they are all the same, could there be any mod that could turn my L-10 into a dual-sim phone?
Thanks in advance for your answers
No-one replied and I doubt they will.
The short answer is no you cant.
The long technical answer is the phone is made with certain hardware I would ask you first how do you think a mod would work try to think that one through logically.
The phone only has one simcard slot and one antenna and the software / drivers is compiled and installed accordingly.
If you think you can just buy a usb simcard adaptor and magically turn the device into dual sim it doesn't work that way.
And if you didn't want a external device connected by your usb plug you would need to modify the internal phones SMD surface mounted hardware and thats not easy when they are built on robotic machines as you can see in this video.
Think about rooting all system level things is behind root and the rom would need to be modified for such functionality if it even existed.
Also the actual hardware and eproms inside the phone isn't designed or coded to work this way even if there is a usb simcard adaptor.
There is a modula phone in concept Project Ara by Google and another phone had a kickstarter that failed to get the concept of the ground and this could be the only way to do it in the future if the concept is realised.
Thats the basics of it simple and technical wise.

This is not entirely true.
Huawei suggested there was dual-SIM capability in the Ascend P7 at its launch, with a second SIM supposedly able to sit in the SD card slot if you value connectivity over storage space.

That is true for the dual Sim models like L00 that I use as I do use 2 sims.
The question was how to mod his single sim phone L10 to dual Sim which I answered correctly as the single Sim models hardware is lacking the physical bits and drivers in the kernel etc for a second Sim card likewise how the L00 lacks the internal hardware components and drivers in the kernel for NFC, this is also why the Roms are incompatible between models as well as different components like the radio freq for different regions which they all use different kernel drivers.
It would be the same if a L00 user asked how to mod NFC into his phone when there is no physical tag reader component on the circuit board.
The question was not if the p7 came in a dual Sim variant.
I was also correct on project Ara concept as no phone currently available in the world let's you change internal components like upgrade or swap your camera from 8mp to 15mp or swap in in a screen with higher DPI, memory or internal storage or even swap the sdcard module for a second Sim or something.
It's a concept Google and some others are looking at our of interest just because they can.
i think drguild is right. may be the same reason why huawei didn't include the L-10 to the list of phones that will recieve OTA firmware upgrade., Only the L-10 phone can't use dual sim., it doesn't even have any features or some sort of settings for it., even if the micro SD slot can adopt the nano sim. it seems that it doesn't have a way to operate it.,
this is not a down for this phone. single sim phone has lot of advantages than dual sim phone. like battery consumption., and phone speed.
some samsung models can enable single sim to dual sim. like s7. some asus phones can changing sim module to dual enabling dual sim but with single imei. i have damaged p7 single sim i tired change sdcard slot to dual sim holder but does not worked.

Please help, No Sim Card/Emergency Calls only

Any advice would be greatly appreciated. I have searched and could not find an answer to my issue. I purchased a T-mobile variant Galaxy S6 it was stuck on the Samsung logo but I only paid $100 so I figured worst case scenario sell it for parts. I managed to get it to boot everything works except cellular service. If I remove the Sim it says "Sim Card Removed" Restart. After restart it goes immediately to No Sim Card . I insert the Sim and it says "Sim card Detected" Restart. After Restart No Sim Card???? Checked IMEI its clean, flashed stock via Odin, pulled what little hair I had left out. Any words of wisdom? Thank you in advance for your time. forgot to add no mobile networks option at all in settings?
Does the SIM card work in another phone?
yes sim card works in other phones
Could be why you paid $100 for it. If your SIM works in another phone then there is a issue with the S6 being able to read your SIM. Have a friend with T-MOBILE? Try their SIM card. You might have a picky SIM.
of coarse it's why I paid a $100 for it, no matter what I can get my money back out of it but I was hoping to be able to fix it. Tried several sim cards same thing it recognizes the card restarts no sim card. I was thinking it might be the sim card reader itself but the fact that there's no Mobile networks in settings makes me think it's software related? Oh well I guess parts on ebay here I come. Anyone need a new display LoL
Same issue
Hi there. I have exactly the same issue with an O2 unlocked S6. I used my Ee sim on it till two weeks ago when suddenly i lost all network capacity (same as you). Previously i flashed an unbranded stock firmware in order to get rid of the o2 logo (may seem stupid but that was what i did). After 2 weeks of normal use with the new rom suddenaly i couldn't give/receive calls /texts. Since, i tried wiping, flashing, advanced wiping etc but same issue. Any advice is more than appreciated.

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:

Dual Sim P20 activation, any tips please ?

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.

Note 8 N950F - Convert to dual sim?

Hello,
Am new user of note 8 N950F.
At my last phone, i was using 2 sim cards. Now i see that N950F support only 1 sim card and 1 memory card
Is there any way that i can use 2 sim cards in n950f?
Thank You!
I don't think that is possible for the N950F. As it is designed to as a single SIM device.
Sorry!
Please delete post!
Strange how there's 2 sim toolkits running still.
I'm ok with pie but oreo starting to sound better.
Call recording and dual sim would be nice...

Depending on where your device originates from you may stil have call recording after you hae installed Pie onto your device. I installed Pie onto my N950N and I still have Call Recording on it.
if you device comes with the hybrid simcard tray, you can either use dual sim & no SD Card, or 1 sim and 1 SD Card.
Back on oreo you can buy those adapters to use 2 simcards and 1 SD card simultaneously but on Pie (One UI) samsung decided to block it.. so you can either use Dual Sim & No Sd Card or 1 sim & 1 SD Card.
I hated this.. so i went out to installed a pre-rooted custom rom as close to stock i can find, which the ROM maker edited it to accept the dual sim & 1 sdcard mod. I lost my knox and samsung pay, bt got samsung pay to work on my samsung gear sport instead. dont misunderstand me, spay still doesnt work on the phone but can work on gear sport if you hide the spay related packages via magisk hide.
Secure folders dont work anymore unfortunately. it was my favourite to "hide" apps and a seperate and secure photo gallery..
as for call recording, google decided to kill off 3rd party call recording (yes, google not samsung did it).. BUT since android has native call recording, and is activated via CSC, and having a rom that is pre-rooted, i went ahead and activated call recording.. and enabled camera shutter sound option (to enable the option to switch off camera shutter sound in camera app)
so, if you do not mind loosing knox and knox related features, go get yourself a custom rom. (i personally went for Dr Ketan's ROM)
Thank you!
This sound good because andorid version on my phone is 8.0.0 and smasung experience version is 9.0

But this isn't really dual sim.. U can only use 1sim at a time. Unlike real dual sim with active standby for both sims

You are right!
Don't think you can truly convert a single sim phone (SM-N950F) into a true dual sim phone (SM-N950F/DS).
Because I think you'll need 2 IMEI's numbers while the SM-N950F has only one IMEI number. So that is probably the only choice is to switch between the sims.
I deleted my first post because that was more for the dual sim phone and not for the single sim phone. Sorry for the confusion on that!
Hopefully someone has figured something out for the single sim phone to use 2 sims at once (1 active and 1 in standby mode)!
Wish the OP luck on figuring this out!
Ohhh, on sime per time. Is same as single sim
I will continue use my single sim note 8
yes, this isn't a dual sim this way. In my opinion is dual sim constantly have 2 number available.
Like the SM-N950FD
