The sim card can be recognized but cannot be used
What SIM do you have? Do you use T - Mobile, etc. or do you use Verizon?
I can always give you your modem. img if you require it.

China Mobile Sim card，phone is Verizon
I don't believe it was a good choice to buy a Verizon model OnePlus 8 in a region where Verizon cannot be used at all. China Mobile SIM cards can likely not be used in the United States and are likely not compatible with U. S. devices at all; hence the reason to buy a different SIM card when travelling to a different region. do you know if your device is unlocked?
Xryphon said:
我认为在根本无法使用 Verizon 的地区购买 Verizon 型号 OnePlus 8 不是一个好选择。中国移动 SIM 卡可能无法在美国使用，并且可能与美国设备完全不兼容；因此，在前往不同地区时购买不同 SIM 卡的原因。您知道您的设备是否已解锁吗？

I'm in China，when i use Verizon oxygen os my sim card have signal，just me flashing other rom my phone signal don't work，The sim card can be recognized but can't connected and use
It's possible that custom ROMs somehow don't support China Mobile; does it say anything when you enter the Mobile Data settings?

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.

Just Google the Mate 9 LTE bands, so you don`t have to guess ....
Me and my friend both bought the mate 9 from the same store. He has the new update but when I try to update it I don't get anything.
Does anyone know what is the issue or how I can officially update my mate 9
He just update his phone from b136 to b138.
Try swapping sim cards between you and him.
Are you both have huawei id registered?

Huawei is known to sometimes restrict upgrade deployment by IMEI and operator so switching SIMs might trigger it.
Alternatively you can use FunkyHuawei.
Sent from my MHA-L29 using XDA Labs
I had to laugh a little, we all bought ours from the same store.
Try without your sim card in it also. Could manually flash with funkyhuawei also.
Not sure why they are limiting the update to imei, it's crap idea from them.
Probably to spread the load on their servers.
Or there are slight component differences.
I can confirm that swapping sim card will instantly detect updates to download since I was in C636B110 before. Even a dead sim card from the region that allows the update will work as well. In my case, I swap my Canadian Rogers sim with a dead HK sim and it detected updates available.

Hello,
I have a Honor 8 AL00, and i wanted to flash a custom rom into the phone.
I encountered the problem where it showed Error 7/E1001 while flashing the rom.
While reading the replies of a rom i found this: https://forum.xda-developers.com/honor-8/development/rom-t3606257/post73158733#post73158733
I followed the instruction and it worked, and successfully flashed the rom.
The problem is that after i open the phone i found that no sim card were detected, even though there are one.
I decided to change the custom rom but still it couldn't detect the sim card.
So now i reverted back to L04 internation rom and i am using it.
But i wish using the custom roms, Any solutions? Thanks!
Nope, no solutions, im in same situation. Till developers dont make 3G sim cards work i cant use any of the custom roms.
well its a 4g/lte sim so i dont know if it changes something...
also, i had a pin in the sim card so maybe thats the problem

Can you try switch back to stock and then see the behaviour. Or remove pin there and cone back to custom.

Is it a 4g sim and in sim 1 slot? If any of this is NO then it may not work on custom ROM may be. Similar issuess were reported for 6X but nit sure if that exist in other models too

Go for debranding. There is already a pist in guide section or rom section.
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

1. First of all unlock bootloader and u also have permanent sim unlock from t-mobile.
2.After unlocking your phone will restart, setup your oneplus 8 and enable developer mode and in developer mode enable "usb debugging" .
Note: You must have working adb/fastboot drivers.
3. now restart your phone to bootloader.
4. Download any android 10 fastboot Rom from xda developer.
"I have tested this : https://sourceforge.net/projects/fastbootroms/files/OnePlus 8/10.5.9-EUROPE-OnePlus8Oxygen_15.E.18_OTA_018_all_2007160043_913306-FASTBOOT.zip/download
4.1. For flashing this rom your phone has to be in fastboot mode.
5. After downloading extract the rom and open extracted folder and double click "flah_all.bat
5.1.connect your phone to computer in fastboot mode and enter "Y"
wait for 5 to 7 minutes, in this process your oneplus will restart to recovery mode but never unplug the cable or use your phone during installation.
Note: i have tested dual sim with dual sim tray.

If you do incremental ota to c.63 , it will be just like updating to OOS13. You will get a null imei 2. SIM will work without any problem.

If you convert through msm method and update to oos13, you will have weird sim bugs. If you reboot phone, your sim will not load for atleast a minute or two. That problem is gone with new conversion method.
