My device is j7elte (running Los 17.1) and using one Sim card named Grameenphone (BD) which is 3g it works well in two sim slots. Recently I buyed a same Gp Sim with support of 4g I inserted this Sim on both Sim slots it detects but says no service . I know first sim slot of my phone supported 4g and 2nd one is 2g I tried to swap Sim cards in different Sim slots first Sim card (which is 3g) it detects and work fine but the new one doesn't work .I tried dialling ussd it says no network available. I clean flashed the ROM again .. Previously I was in an a12l ROM . I changed to Los 17.1 also tried few aosp Roms with clean flash but same result. .. Can anyone help me I'm a newbie. Sorry for bad English. Thanks in advance.

Either your SIM has a problem or the ROM has a problem.
1) Check if SIM works in other phone.
2) Flash a different ROM and check again for network.
3) Check if another SIM works in the Nexus S.
4) If none of the above work then may be your SIM slot has a problem.

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 ....
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.

What an tragedy
Had same issue with Airtel SIM, same sim was working in another phone and Jio sim was working in x3pro. Had to go for replacement of sim which fixed the problem. Not sure what was the issue.
Thank u
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.
