Hello, thanks to my carelessness, I think I broke my dual sim functionality.
What I was doing was messing around in the network settings in Engineer mode that can be accessed using *#36446337#. And all of a sudden, both sims stopped working. After a lot of messing around with the RAT settings, I could get one of the sims working. After selection sim1 or sim2 in the options and changing the RAT settings for that sim, I can get said sim to work, but it breaks the other. No matter what I do, I can't get both working again. This was on Open Beta 9.
What I've tried doing since then:
1- Factory reset
2- Flashing another ROM (Lineage)
3- Flashing latest 4.0.4 firmware
nothing seems to get both sims to work. Always just 1 sim working. Does anyone have any thoughts what I could try?

Just do a full wipe with the unbrick tool and everything will be back to normal.
I have the same problem after I mess with the engineer mode.
Tried everything and still unsolved.
Try installing the modem or firmware of previous oxygen OS builds then updating the oxygen os

Yes, I tried the unbrick tool but it's still the same. It seems to me that the GSM/WCDMA band of the phone is broken. When put two LTE card into the phone, both can work under LTE band.

Installed the OOS3.0 and then updated to OOS4.0. Dual sim function won't work on both OS.
Flashing modem usually can solve signal lost on Samsung, but it seems that it won't work on Oneplus.

Well you just said you are a noob.. No problem but really dialing a number isn't going to break anything in your phone.. Wipe all partitions then Flash OOS 4.0.2 and o guarantee it will work, this is pure something in software level.
I have successfully fix the problem according to a post at Oneplus Community in China. Just Flash Official H2OS 2.5 (Android 6.0.1 ). Go to engineer mode. Choose Network Set -- Band mode --Hardware Default (Foreign) to fix the problem.
P.S. If you are in mainland China. Pls choose Hardware Default(China). Else choose (Foreign)

Hi everyone,
I am using a Oneplus 3 A3000 China variance. It was shipped with Hydrogen OS.
So i have unlock it and managed to flash it to Oxygen OS, as i need to use google services.
Everything was working perfectly fine until a couple of months later. I saw that Oreo is out and thus decided to upgrade it.
Using official method with stock recovery, i have managed to upgrade to the latest OxygenOS 5.0 using the below link
Oneplus 3 OOS5.0
I have followed the guide closely. Then after it reboot, my phone is no longer having service.
It will show my network SINGTEL (No service)
I have read close to 50 forums before i decided to post and seek help.
My phone info
OnePlus 3 A3000
Oxygen OS 5.0
Android 8.0 Oreo
Kernel version 3.18.66
Build number A3000_16_171116
Baseband MPSS.TH.2.0.c.1.9-00102-M8996FAAAANAZM-1.99649.1.118107.1
Stock recovery
Non root
Fingerprint, camera wifi all works
Both imei are still shown
Here is what i have already tried which all fails on me
1) Verified that Sim is not faulty. Have tested with 3 different working sim cards and it all shows no service on both Sim 1 and Sim, but works on my other phone
2) Tried using only one sim card at a time for sim1 and repeat with sim 2, same result as above
3) Remove sim card, power on phone and boot fully, power off phone and insert sim card and power it on again
4) Reset to default access point. Copied all settings from another phone using same telco access point setting and ensure its the default sim for data and services
5) Using *#*#46463*3* and set preferred network type
6) On the same menu, disable mobile radio power and reboot
7) Perform factory reset from phone phone system setting
8) Redownload OOS5.0 and reflash rom using stock recovery
9) Relock bootloader
Any help is greatly welcome. Phone no longer have warranty so i can't head back to the service centre.
Thanks for reading

Try the 5.0.1 update, maybe it works. https://forum.xda-developers.com/oneplus-3/how-to/oxygenos-5-0-1-ota-update-oneplus-3-3t-t3727433

Take SIM out. Reboot phone. Once powered-up, put SIM back in. This worked for me, even though it's a pain.

Have performed that too on my point 3
Tried something new today. Flashed back to Hydrogen OS hoping that it can detect my sim network
But sadly, it still does not detect.
Hello Guys
With unlocked bootloader, I have been to China and used local sim over there.
Now I am back to India and none of Indian SIM cards are getting detected by phone.
I tried all possible options, did reset..downgraded to Oreo also..but no luck. What ever sim card I try, it's not getting detected.
In device info, it's showing mobile radio is off, tried switching on several times..but no luck.
Can someone pls help me ASAP.
Regards
Pavan
Try resetting network settings or hard reset the device and also try flashing factory image if previous doesn't work.
If your bootloader is locked then try reaching customer support. Else, you can try restoring some efs/modem backup using twrp.
Do you get any notification when you insert the sim tray?
I may be wrong just sharing my 2 cents.
Same problem here (or similar, at least).
My 5z recognized the SIM card on both slots, but no signal.
Tried all of the four carriers from Brazil, tried a hard reset, tried the Android Q beta, switched back to Pie, nothing works.
BTW, I've seen three devices with similar problems recently. One Samsung, and two Motorolas. All of them was updated to Pie. Could be some update bug?
My problem was fixed after the May update that was released a few days ago.
Everything working fine, 4G, LTE, etc.

Hi
So before anyone tells me to just insert a SIM and be done with it, please read this first. I'm trying to unlock the bootloader so I can try flashing different ROMs and radios. I had a perfectly working global version of the Redmi 7. After a phone call, the network went off and wouldn't return.
What I've tried so far:
•Trying multiple Sims known to work
•Manual network selection (fails because it can't find any)
•Changing preferred network modes and bands with the *#*#4636#*#* menu. Nothing happens.
•Toggling airplane mode, several times.
•Factory reset, both from within the OS and from the recovery (Vol Up + Power button)
•Attempting to flash a Fastboot version of the latest global MIUI 11 ROM. This actually fails, saying that critical partitions can't be flashed or something.
•All sorts of bootloader unlock tricks, such as the older versions of MiFlash Unlock, using multiple accounts, etc.
I'm honestly stuck here. Any help in fixing my problem would be appreciated. It could be either getting the network to work, or unlocking the bootloader. I can't bind the MiAccount to the phone under developer options ->MiUnlock status or such, because it detects that there is a SIM in the phone alright, but it just can't connect to any network.

Was the SIM card's network working before? Maybe you're just in a dead spot?

It was working fine for a few months. It just stopped being able to connect to a network all of a sudden. I swapped SIMs, moved to places with strong network connections (I verified with a different phone) and still nothing.

I need to root my redmi 6a but bootloader makes a big trouble for me .for unlocking bootloader there must be sim in that device.but I doesn't have a sim card and even if I insert it, my sim board is damaged. So is there a way to unlock bootloader without inserting sim.
My POCO F3 8GB/256GB suddenly not letting me call anyone (Says mobile network not available) or pick up any calls but mobile network and texting is working completely fine. I've rebooted the phone multiple times, disabled volte, reinstalled google carrier services and still nothing so I had no choice but to factory reset the phone but that didn't work too. Currently using MIUI 13.0.9 and hoping there's a way to fix this asap.

Use miui flash tool to reset your phone to he miui version it came from. If it does ot work then, it's a hardware problem.

So I've tried using 2 different sim cards (One of them being the same carrier as the sim that's not letting me make or receive calls on the F3) and so far those sims are working fine with the phone . Also tried putting the not "working" sim on other devices and it seems to work fine so I'm not really sure what's the problem here. As soon as I put the sim card back on the F3 it works for a moment then completely stops letting me call and receive calls.
Try changing network modes.

Try manual network selection. If fails probably hardware.

Hello everyone. I have a realme GT Master Edition (RMX3360).
The problem I am facing is that, SIM network does not work. SIM is recognised but it won't connect to any network, so basically I cannot use the SIM card even though the phone knows what SIM is this.
I did try:
Factory reset.
Use Force LTE app to access phone information and switch bands (I noticed radio toggle is switched off, I tried turning it on but it won't).
Unlock bootloader, just to increase my chances.
Flash only modem/hlos/... related partitions. Did not work (phone bricked).
Flash OFP firmware. Did not work.
Flash EDL firmware (C.09), which I am currently using. Still same problem.
Different SIM cards.
My IMEI is fine, it is recognised. My baseband version is 4. I did search for the issue in realme community, and it seems quite popular as a lot of people suffer from the same issue on different models.
I live in Sudan, we got no 5G, no VoLTE or whatever. Could you help me please?
I have similar problem after reboot .I can't connect to network or it tooks long time . What helps me is switching to airplane mode.

Thanks for the suggestion. I did install RMX3363 EU ROM from EDL, it booted fine but the phone still won't connect to any SIM network.
I will also try Russia ROM to see if it would make any difference.

I did flash Russian ROM from EDL, still does not work. Modem version is also still 4. I will try Chinese ROM next.
Try Latam version this what they put in middle east but so far i think its hardware issue did u try the sim card on another phone? Did you try another sim provider on your phone ? Sometimes if the sim card too old it wont work

That LATAM version is 18 Gigabytes haha. It'd take a few days to download.
I came to think it might be related to modem images as it showed the same version repeatedly on both RUI 2 & 3. So I'll try different modem images.
Also I'll try custom ROMs and GSIs. If it failed I'll return the device as a very last resort.
Update:
I tried latest Official ProjectElixir till date, still same problem.
Update 2:
I gave up the device and replaced it with another one under warranty. I will not buy another realme phone anytime soon.

I have a Xiaomi device too. The new virtual proximity sensor depends on hand movement to function. I don't use MIUI, but it is very fine at all situations.

It was already updated to F.03, I heard there was screen flickering or something but I didn't notice any so far.
But I did notice the battery was draining fast on mobile data. Really fast.
Besides, I can always lean on post-market development.
