No Sim card detected after flashing to custom rom

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.

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

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.

Both Sim Cards deactivated after latest update

After updating to the latest update, android 11 global for poco f2 both my sim card slots have been turned off.
When i try to turn on sim1 it tells me that only 1 sim card can have 5g enabled and to change my network settings.
Unfortunately none of the slots wont turn on so i cant change the network settings for either sim.
Have tried putting in 1 sim and restarting, in either slot 1 or 2 the sim slot still wont turn on.
Is there any other way to do it other than a factory reset?

I have same problem with you. I cannot turn on sim card 1 or 2. İt is very weird problem. Did u solve the problem ?

A hard reset maybe help

Yeap i did it. I had another bugs after the update. But factory reset fixed all of them

This version (stable BETA) in android 11 has multiple bugs. Many prefer to revert to the previous version.
https://forum.xda-developers.com/t/...11-general-discussions-bugs-features.4165065/

Great,! Wish I'd bloody read this thread before I updated. At least I know now, it's not just me. Unfortunately, for me at least, I'm on stock & haven't modded, unlocked bootloader, rooted or flashed anything at all. Does anyone know if Xiaomi's backup utility is any good or shall I not bother before I factory reset?. Cheers.

Question poco x3 pro sim card detected but not working for calls

hello guys,
my friend has an issue with poco x3 pro the doesn't read properly a sim card, it works only for data and not for calls ( lte is not forced , did already a factory reset, update firmware, tried custom roms, swapping sim card between slots, same issue always ), the thing is this issue comes only with a specific operator sim card and not for others, ( knowing that this sim card works properly on another phone )

Ask the specific operator to give a new SIM card for your mobile number.
Sometimes there's issue in old SIM cards.
If it's still not working properly, there's chance with 2G/3G/4G bandwidth issue.
What mobile operator and which country is that specific operator? Maybe someone had same issue you have and can help you.

Sim 2 not working/ Unable to enable after update

I have bought OnePlus 8 used. At that time dual sim was working fine. However, the phone was not updated. When i started updating there were 3 updates pending and phone downloaded and installed them one after another.
After update i noticed tha sim 2 is not showing in status bar. In settings sim 2 is showing, however when i tap on it, the menu is all gray out and the enable button cannot be taped/ enabled.
It also shows the sim 2 operator name and sim number but cannot enable it.
When i remove sim tray it also shows no sim icon in status bar with 2 sims icon.
I have tried replacing sim cards, restarting with areoplane mode but no luck.
Please help how can i again start using the sim 2 as it was working fine before update.
Current version: IN2015_11_C.33

Perhaps, after each update, it was necessary to check the operation of both SIMs, or perhaps it became too many changes at once and a conflict appeared somewhere.
If you installed OTA update, try to backup important data first, remove both SIMs, restore the phone to factory settings and insert the SIM cards one at a time (restart after inserting and setting the first SIM).

@shafiqb9 have u solved your problem.

Nope. Downgraded to OOS 11 for using both sims.

It was a single sim mobile,
