Huawei mate 9 chinese version. Sim card not detected

Hi. It is the first time I'm asking a question on this forum and I'm definitely not a cellphone expert.
I purchased a mate 9 from china MHA AL00 version B136.
The phone is working great, using Google play with GSM core.
However, I just inserted a nano sim card from Rogers (in Canada) but the phone is not able to detect it.
Any reason why I have this problem?
Thank you very much

Try different sim card ,also make sure to reboot after inserting the new sim card.

How To check whats the official version of MATE 9?

Bought phone Mate 9 second hand.
How can I be sure what version is it or if its been rebranded?
About phone says its a MHA-L09 and build is L09C432B182
I tried to upgrade it to newest b193 with method in this post [Guide] Mate 9 Flash Update Package and Rebrand
but after upgrade i noticed I lost MEID just zeros, same with PESN when type: *#06#
I am not sure if those numbers were the same before upgrade or something just went wrong.
Other thing is that phone doesnt recognize sim cards after upgrade, it works fine with b182, even if I do upgrade with normal software upgrade throuh phone it finds b190 and again sim is not recognized.
It made me thinking ,how can I actually know what version of Mate 9 i have? I went to huawei web site to check warranty (http://consumer.huawei.com/in/support/warranty-query/index.htm) for this phone and acording to its serial nr/ imei and it says its a MHA-L09B ?im slightly surprised as i found out L09B is an Australian model? live in UK . my serial nr is UGM0217122003582 can someone advice? also if its L09 so i suppose it should have only 1 sim , then why if i go to mobile network there is an sim 2 network field (grey out) ,is that how it should be?
thx

You have 2 sims cause u rebranded ur phone from single sim l09 to dual sim l29.
Better to rebrand it back to l09 so you can hve ur iemi back and working network.

Read carefully , I have IMEI with all brands , I lost MEID and PESN not IMEI, also never rebranded to any l29 always used l09 that's the point

Are u sure it was L09 Firmware u used? Because if it shows that u have 2 sim now u used L29 Firmware when u flashed it, if u flash a L09 that is the singel sim version with a L29 Firmware it will show that u have 2 sim slots in the Settings.

1. bought phone mate 9
2 have no knowledge of its history and if it was rebranded or not.
3. phone info clearly shows MHA - L09 C432B182, IMEI was also there and mach serial number according to huewai warranty checker
4. tried to upgrade many times to newest MHA-09 C432193 but always had some issue with it finaly somehow i did it, phone info was showing MHA - L09 C432B193 IMEI was there but i noticed there is no MEID just zeros
5. confirmed that with dialler: *#06# MEID and PESN have just zeros IMEI is there
6. inserted sim and phone had to noticed its there as had pop up from sim vodafone if i want to use prepay or postpay, after selecting either of two : no service.
7 in settings , mobile network there are 2 sections sim 1 and sim 2 both ,grey out
8 rebranded phone with MHA - L09 C432B186, all went ok but results the same, phone upgraded mobile network still shows sim 1 sim 2 both greyout, no service
9 again flashed phone with MHA - L09 C432B182, straight away phone picked up signal. mobile network still shows sim 1 filled with info and sim 2 greyout.
10.having installed MHA - L09 C432B182 i upgraded software through official way settings ,system upgrade : system found MHA-L09C432B190 proceed with that , as a result system upgraded but again sim 1 sim 2 grey out no service.
Thats why im wondering if there is any way to find out phone original region/brand/version ? how can i know if i got L09 or L29 regardless software it has installed?
Something there is definitely not right if the official phone upgrade screws things up ,there is no service and only firmware that works is 182.

Seems it was single sim branded phone and the previous owner has flash it to single sim unbranded.
I think l29c636 firmware can fix it. Just flash an approved firmware.

No service in European L09 C432 ROM issue

Hello everyone, i know that here collected the best minds of Huawei custom thing development
So i have a question to you, and i hope that you can help me, i dont know there to search and what to do
Originally i had a Mate 9 with L09 C432 ROM (UK Three mobile), after time i decide to flash custom rom, to get a better battery life, root and another tools
Because my phone is insured i have to bring this to original ROM one day, but.... Now when i am flashing any version of L09 C432 ROM i dont have network access (cannot use mobile data), cannot make calls and messages, but i can receive calls and messages. In row about phone i have MEID 0000000000. In top left corner there should be carrier written - No service, looks like that phone think that he is now 2 sim model
No service
One ROM from L09 which one is working for me is RomAur 1.5
I tried to rebrand to another model, and after back to original, not working, all possible roms - same issue. I dont know which part of ROM responsible for receiving calls and messages, or what i destroyed in my phone
Any idea for this?

Hello.
I'm not a developer or something likewise, I'm just a regular user. I have a mate 9 bought in latin America (Dominican Republic) after a month I rebranded my phone from MHA-L09C25B106 to MHA-L09C432B182. My phone was built with a single SIM and when I installed the ROM from this post. https://youtu.be/8OywEYZ2cbw it also gave me the MEID 00000000000000 but it let me do call and use data, also I noticed that even if the ROM was for MHA-L09 it has two SIM toolkits, one with the name of my carrier and the other with none but the phone was fine. The problem came after I updated to B190. I had the no service massage even though I had my SIM card inside, what I did was while on I took off and back on the SIM card and the service came back on, I restarted and came with the same thing so I took it off and back on again and my service came back. Because I use a case I don't want to be taking it off plus doing the same with the SIM card so I reinstalled back the MHA-L09C432B182 and don't allow the system to update itself.
I recommend for you check your version if it is ...B190 and also do the SIM off and back on solution.
Hope this helps.

Yep I have to eject and reinsert the SIM. Rebranded from L09C185 to L09C432B190. (SINGLE SIM)
Any fix for this on B194?
Will I have the same issue if I rebrand back to L09C185?

Does T-Mobile OP8 5G Support Dual-Sim if on Global Firmware?

I was curious as a colleuge of mine recently purchased the OP8 5G from T-Mobile rather than directly from OnePlus. The sim tray only supports one SIM, and I am assuming that as it has been done historically on prior OP devices, the T-Mobile OP software only supports one sim card. I am unsure as to whether the T-Mobile variant has hardware to support two sims or not, but I think it may only a software issue. Would rooting and flashing to get onto the Global firmware enable dual-sim support for a OP8 5G T-Mobile variant?
Thank you,

I'd assume so. I'm planning on trying this myself when my dual sim slot comes in from Shenzhen.

What is the dual sim's use case for you? International travel or work/personal use?
I think in Asian countries, people often get 1 cheap SIM for cheap voice plan and another SIM for cheap data plan.

In my colleague's case, for work and personal use. I personally have my OP7 Pro as my work phone, and it is the unlocked non-carrier variant, so the dual sim support is there. However, for my use, too, I would like to have the capability available on my T-Mobile OP8 5G just as my colleague. I had him order a dual-sim tray from eBay, and from a US seller to get the item faster. If it works for him, I'll likely order the dual sim tray.

i dont think the global or eu roms support dual sim. there was a disclaimer under the network & sim settings untill ob1. not sure if ob1 supports dual sim yet

Dual sim works, however, i cant get my Verizon sim to work with t-mobile. I get the CDMA-less notification, i read that you can get it to work, you just got to call verizon to register your imei with them so dual sim can work. This is running open beta, stable 10.5.12 wouldnt see my second sim.
I havent called them because my verizon sim is through work.

And, this is on a T-Mobile OP8 5G? If so, I wonder if my colleague would have any issues running two T-Mobile SIMs on a global ROM? (I suspect the T-Mobile software doesn't even recognize a second SIM).

Yes, this is on my t-mobile OP8. I converted to global because I prefer global. I haven't tried two t mobile sim cards, and I haven't tried using t mobiles firmware.

So, after receiving the dual sim tray, and inserting two SIM's on T-Mobile's software--it does not even recognize the second SIM. What particular guide did you use to port over to the global firmware? Thanks!

I would also be really interested in knowing how to get the second SIM to read on the T-Mobile IN2017 variant of this phone. I've been tearing my hair out trying to get this to work, now that I've seen that the international models running Android 11 OB2 seem to have functional dual SIM. Personally, I kind of gave up on getting Android 10 to do dual SIM- even with the European ROM (which I'm fairly certain is the only way dual SIM on this device was ever officially supported by OnePlus), I haven't gotten it, but I think I'm annoyingly close. T-Mobile MSM to Global 10.5.12 to Android 11 DP2 will get you non-functional dual SIM- the device will see both SIM cards, and will properly identify them and their phone numbers, but the second SIM won't connect to voice or data, no matter what I do. If I upgrade the device from DP2 to OB2, the dual SIM UI stays (if I go directly from Global to OB2, it doesn't show), but the second SIM slot is still non-functional- no service for voice or data on the second SIM.
For anyone who has gotten a T-Mobile OP8 to properly read two SIM cards, I'd really like to know how- through my hours of messing around with this thing, it always seems like one step forward and two steps back. Hopefully the final release of Android 11 clears this up.
(My two SIMs are from T-Mobile and AT&T, respectively. Unfortunately, I don't think two T-Mobile SIMs has a chance of ever working with this setup on any firmware- "SIM 1" and "SIM 2" share an IMEI. While that's probably okay for SIMs from different carriers, that's not going to fly on the same carrier- it will look like a cloned IMEI to the network, and probably get shut down fairly quickly.)

Has anyone managed to make it work the Oneplus 8 (pro) unlocked USA version with 2 sims at the same time ? Thank you

It's working on mine with second simbtray however there is no service with both inserted. BecUzebitvhas the same IMEI as slot 1

OP8 IN2017 (TMO) to Global Dual SIM

Has anyone been able to get dual SIM working on their T-Mobile OP8 after flashing to the Global ROM?
I have a dual SIM tray and whenever I insert two SIMs, I get service on the first, and the second is recognized, but refuses to connect to any network. This applies to any second SIM inserted. The IMEI numbers are showing as the same for IMEI1 and IMEI2, but that shouldn't be an issue as far as I can tell.
Thanks!

I have same issue did you find any fix? Please let me know

I was recently able to "rebrand" my OnePlus 8 T-Mobile 5G phone from the T-Mobile version to the European version using these steps (I tried with the GLOBAL version but it DID NOT work):
1. Unlock the bootloader. Steps given in:
https://www.oneplus.com/support/answer/detail/op588
2. I was able to to use the MSMTool_instantnoodle_tmo_15_O.06_200411.zip to go back to 10.5.7.IN55CB
(OnePlus T-Mobile Android build) using the method given in (GLOBAL version FAILED for me here) :

Tool: https://androidfilehost.com/?fid=4349826312261823571
3 Repeat Step 1. Go to Step 4.
4. Next, I upgraded to 10.5.9.IN21BA (OnePlus European Android build) by flashing 10.5.9-EUROPE-OnePlus8Oxygen_15.E.18_OTA_018_all_2007160043_913306-FASTBOOT.zip using the method given in:

Tool: https://sourceforge.net/projects/fastbootroms/files/OnePlus 8/
5 Repeat Step 1. Go to Step 6.
6. Finally, I upgraded the phone to the latest OnePlus Android version for this phone through System Update to 11.0.9.9.IN21BA (OnePlus European Android build). Now Dual Sim capability is installed but it does NOT show.
7. Relock the bootloader and NOW dual sim capability shows under SIM & Network.
What I don't understand is that the model, IN2017 (T-Mobile), remains the same but when you boot the phone, the T-Mobile logo does NOT show and it boots like a non-T-Mobile OnePlus phone. I expected the model to change to the European model number (IN2013). My goal was to get Dual-Sim working as it has been banned by carriers here in the good ol' USA. My phone now shows 2 sim cards, originally it only showed 1. Now I have to verify what signals it really works with (5G, 4G ?) and if the dual sim capability works.

I went to Verizon yesterday with the setup written above and the second sim did register as Verizon with the first card in slot 1 as T-Mobile. The problem was that we only tested it with 5G. 5G did NOT work with both sim cards placed. I should have put my phone in 4G to see if THAT works. I will go to another Verizon store later in the week to see if it will work in 4G with both sim cards. Hopefully it will.

I went to the Verizon store yesterday and they said that I needed to open an account and activate my phone with that account in order for the Verizon service to work. I was under the impression that all you needed was a Sim card with an active Verizon account and a phone with a good IMEI. I asked them to use a spare Verizon card at the store to test it just to make sure it would work. He wanted me to sign up first which I wasn't going to do. I will have to find another store. Am I correct in assuming that you can just use the sim card from another phone and the service should automatically work ? Or do I have to "register" that phone with Verizon ? F%^k Verizon. Thank you.

So I went to the Verizon store yesterday and brought my OnePlus 8 (IN2017 updated with Oxygen OS 11.0.9.9IN21BA European version). I brought it in unlocked and the Verizon clerk told me it was "dangerous" to leave it unlocked and advised me to lock it (of course I did not). I had my phone set to LTE (4G) under network settings and the two SIMs slots were showing with the first one occupied by T-Mobile. The clerk placed a Verizon SIM card on the 2nd slot and the phone recognized it but IT DID NOT work (messages nor calls). So apparently, according to other users over the web, the blockage of service is coming from the carriers (T-Mobile, Verizon, etc.) themselves. They frown upon dual sim capability and until there are enough complaints to make them change their stance they will continue to refuse to provide dual sim service. It may work in Europe and Asia, but here in the US, not a chance. Talk about UNFREE market.
