sim cards turn on and off. oneplus 8t - OnePlus 8T Questions & Answers

hello everyone. I made the translation from google, sorry if I'm wrong. my phone is oneplus 8t as it says in the title. I've been using it for 3 months, for the last 2 weeks my phone disconnects after creating the sim card connection and this keeps happening. I tried a lot of solutions, sent it to the repairman but the result is still the same. does anyone know a solution? Thank you to everyone who has already helped. I sit at the computer in the evenings and it may be too late for me to reply and test. I'm sorry for that. You can be sure that I will follow and try everything written. I'll get back to you when I try it. If what I wrote can't explain the situation for you, I can upload a video next time.

Hello!
First of all check that sim card is good.
Try swapping it in another sim slot.
It it doesn't help you can change it in your carrier office.
If it's not sim issue, you can reset network settings in android settings.
Or update OOS firmware to the latest one.

I tried everything you said before :/ I tried resetting the phone completely and reinstalling it. I have installed the latest updates but the problem is not solved. It seems to me that there is a problem with the motherboard. Thank you for the help. I hope there will be others who offer different solutions.

Did you make sure it wasn't stolen?
Please help .... I have a similar problem.
The SIM card it is inserted in the phone, but the phone still writes: Please insert SIM card
The SIM card is new and in the other device is functional.
Please help .... I have a similar problem. Writes that: No SIM card plugged in.
Please help
try checking csc via phone info.
Any fix to this?? I've just gotten the same problem on mine! Thought it might have reverted back to the region lock as I am now using a USA sim card and started off with a UK sim card. Just ordered a new UK Sim to see if inserting that one will fix the issue
Please .... Solution
Same problem here... No sim card.

I had this issue with my first Galaxy S6... I went into the three shop and checked my sim and that worked with another phone, but my phone would not accept any other SIM card. I was told to send to Samsung for repair, luckily I was in my 30 day amazon exchange period so I just sent back to supplier and bought a new one.
Same poblem here.. When i insert sim card, the phone restart and when enter in Android show message... "Error occurred while unlocking network... Network unlock code block".... Its a Japan Docomo network.. U think that can resolve it with a subsidy code? To unlock a sim?
Solution needed urgent
Hello everyone till now their is no solution anyone can help plz reply,
i tried to unlock by z3x box pro, octopus box and spt box with no solution, even try to change CSC, rooting, reflashing the same problem still!!! . any solution?????

[Completed] No SIM Card error on LeTV 1 pro X800.

So, recently I bought this beautiful phone that came pre rooted with cuoco92's rom. I put my SIM in and was ready to go. But I messed up with titanium backup and deleted the system phone app.I could still call and all, but the menu while in call was gone so I could not hang up etc.
Then I obviously decided to re-flash the rom. Problem is when I did so, the phone's signal icon was grey with a small x . From there it went downhill. I flashed the rom and some others multiple times, I even returned to stock rom+recovery, and the problem changed from what I described to a simple No SIM Card.
The phone now does not acknowledge the SIM when i put it in at all, while before it did know it had a sim inside, it just would not work.
Is there any universal troubleshoot process I can try before contacting the shop and sending the phone back? Could this be hardware?
Note that today I changed my micro sim to nano sim since the phone takes both, in hope of solving it. But it did not work on both slots.
Thanks in advance.
Hello,
Verify that your IMEI(ESN) is still intact, if it is gone then you will have to restore it, the method to restore IMEI is different for each device so you'll have to research how to restore it on your device. I'm not saying that is your issue, I'm just saying it is something you need to check before going further because if it is gone then nothing else you do to troubleshoot/repair is going to work.

The experts there may be able to help. Good luck.
I checked my imei with the *#06# thing, it is there..

Not detecting sim card?

My phone isn't detecting the sim card, but is usually fixed by a factory reset? Is there a fix for this so I don't have to reset my phone every time?
Try another sim first. Sometimes they go bad.
Hello,
I have the same problem with my Idol 3 (Dual Sim) Both sim card does not work. I also tryed a factory reset, but it does not solve the problem.

Try a new sim. Or try a friend's sim.
Has it been exposed to water, dropped, custom rom flashed?

I am sorry to hear that. It seems as though it may be defective. You may need to have it replaced.
I would try a Mobile Upgrade Q first.
Do you see an IMEI under Settings > About Phone > Status?

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 Only 2g network after OneUI 5.0 Stable update

Device: SM-S908E/DS
Region: India
Carrier: Airtel
OS: Android 13 (One UI 5.0 Stable)
I have been facing network issues after installing the latest OneUI 5.0 stable update officially through the Samsung OTA. Immediately after the reboot, the network automatically switched to 2G and hasn't upgraded to 4G LTE/5G since then. During the beta, I had 5G working for 3-4 weeks flawlessly.
Is someone else facing the same issue? I have since done a complete factory reset twice, sideloaded the latest stable update manually via adb. What else can I try? Samsung and Airtel both have asked me to wait 15 days to get this issue resolved.
Try that sim in another phone. Some airtel sims are falling
I have the same kind of issue after UI 5.0 update - Belgium European version.
I 'm randomly missing calls, don't receive sms. Tried sim card in another device no issue. Only way to solve is going in airplane mode and going back to normal mode but it does not solve the issue.
Also did factory reset but it did not solve the issue. Hoping November update to come with fix or new kernel/modem.

Hello Mario,
I managed to solve it by removing my secondary sim card, it seems that it was conflicting with the main one. Since then no more issues but it was 3 months ago and did not test back with two sim cards and i got 4 or 5 updates since then.

Maybe tro to move your sim card from one slot to the other one and test back. Also try with another sim card if possible, or with your current sim card in another phone.

Can i contact samsung for replace or from my service provider where i got it?
Register you device with emei on Samsung site and ask for repair, i think it's always better to pass by Samsung directly. Hope you kept the invoice.
