Sim 1 not detected - OnePlus 7T Questions & Answers

Hi guys,
I recently purchased used one plus 7t 2 weeks ago and i noticed sim1 tray not detecting any sim.. only sim2 tray working.. i don't know it this is hardware issue or software issue.. now my device is bootloader unlocked and i read somewhere on internet that if you unlocked bootloader on one plus device sim1 cannot be use.. is that true? Can someone verify this as im new to one plus device..

Not true. Sounds like hardware issue if broken on factory reset (erase all) on stock rom

Mine needed a new board when I was having that problem. It may be under warranty if you ship it to OnePlus. They usually get it done in less than a week.

Finally I brick my E973,, :(

Couple days ago my beloved Bell E973 wont reay sim card.
Here is what happed. the original from bell, but I bought a unlocked code to use my Rogers sim. It's working perfect for 2 or 3 weeks. I love the screen. personal I like it bettter than S3.
I did not root or unlock the bootloader and one day when I put sim card in, it just said NO SIM. I tried with bell sim. same
So I rooted and tried all kind of ROMs, even F180S. that's fun. but still wont read sim.
If anyone buy it as a parts or want to fix it. let me know. I am in Toronto
You tried to re-unlock it ?
Also, if you flashed korean firmware, your radio will mostly be gone.
no really to re unlocked it, since I tried my friends Bell sim. doesnt work

btw
i saw your post on kijiji lmfao !! we live around each other lmao!!
Did you put it in the proper way?
I made the mistake of putting a sim in the wrong way once on my BB and even took it to a Rogers store and then felt like an idiot after the guy pointed out what I did.

Two things about your phone:
I may be interested in it for parts, depending on price of course. Mine has a dead spot in the digitizer, and as I bought it second hand, LG won't warranty it for me. I'd not want to spend more than the price of a screen/digitizer assembly, so it might be worth more to someone else.
Have you tried a different sim in it? If the phone is unlocked, try a friend's sim card, maybe your sim just died. Edit: missed your reply about trying your friend's bell sim
Have you tried a hard reset?
Have you tried reinstalling the original rom, using the original KDZ file and the "unbrick" method?
Can you browse internet, play store, or use any program with data connection via wifi?
- first, it might be the unlock procedure did it. I had 2 out 5 devices ran into this scenario after doing a factory unlock.
- second, but unlikely and super scarce situations, Bell might have locked up your device's IMEI that caused it. I got one relative that the carrier locked up his phone after doing a factory unlock.
My Rogers E971 stopped recognizing SIM cards yesterday. It is unlocked/rooted. Hoping I can reroot/lock bootloader and send in for warranty service. Still trying to figure it all out.
same problem

I am hoping to set mine back to stock and send in for warranty servicing.
Optimus G sim card inserted or removed all the variations of the device automatically restarts.
Did you notice this situation?
Inhabitants of this problem, removing or inserting the sim card would not open the device?

Woo911, you have used wrong title for your thread thus eliminating people who might know a solution to your problem to ignore the thread, inability to read the sim doesn't mean your device is bricked.

When I first got the phone it would reboot when I inserted and removed SIM cards. It has since stopped doing this.

Just an update. I couldn't figure out how to unroot and relock my bootloader. I ended up sending it off to LG for warranty servicing via my carrier and they fixed it free of charge.

[Q] No Sim Error - You're my last hope!

Hello all!
I have a Note 2 who can't detect my sim card, listen to this:
3 months ago I started to get no sim errors, and after trying everything (factory reset etc), I finally decided to buy a new replacement sim tray.
I got it in the mail and replaced it right away. Damn I was looking forward to using my phone again!
Errr.... Still the same no sim error
Mabye I was extremely unlucky and the new one was faulty as well? Hmm.
I ordered a new sim tray, got it today and replaced the old one.
FFS! Still the same god damn no sim error! :silly: I'm going mad over this ****!
So, it seems like I got no choice but to buy a new phone. (The phone doesn't have any warranty.)
My question is: Has anyone experienced anything like this? Do you have any possible solutions?

Did you test with a different sim? Are you on a custom or official firmware?

Yes, tried 2 other sim cards, none of them works.
I just recently changed to Cynagenmod 10 from stock to see if it would make a difference, but still get "no sim" error.
Do you think this is motherboard related?
It's clearly not the sim tray itself that is the issue here

hard to say, but it could be issues with the board. does searching google give you any info? Try gsmhosting for more info.

Check if your IMEI is correct / the same as when you bought the phone. If you see it has changed or its is corrupt then that might be the reason
to recover your IMEI means recovering your EFS
there is a user here and a htread about recovering / restoring EFS by Drkeaton..something like that .. it very useful and might help u and that mans going back to Stock ROM other than that maybe flash some other ROM stock based though if all fail it might be a hardware fault inside some chip in the mother board !!

Hey there buddy , i have bought a 4g variant and have root... i haven't encountered such a problem yet... I read somewhere on the net that disconnection of network is due to sim card cut in a wrong manner...Do you have a micro sim given by the operators or you just had it cut from a local shop?? try inserting a micro sim which is given by the operators themselves...

I'm using genuine MicroSIM and also I'm using a new sim card. So there is no way it can happen. Are you using Dual SIM?
In zentalk forum, many has reported this same problem....

LG H815 sim card not recognised

Hi guys,
Don`t know if it happened to anyone else but maybe someone can help me.
I bought an LG H815 from Vodafone UK > 2 years ago and unlocked it with an ebay code. It worked just fine until February this year ,1 month before expiring the warranty. I sent it to LG UK and got replaced by a new one.
The new one was also locked I unlocked it again using an ebay code but after few days I started having problems with the signal.
I was getting a message "no sim card" and my phone restarted.
First time I thought that the sim mooved and I put it back but it kept on doing like this.
The thing is sometimes is working for a few hours sometimes it`s not working at all.
Tried different sim cards same thing happened with the phone, tried my sim in different phones was ok.
I also did a factory reset but nothing changed.
I asked the guy who sold me the unlock code and he said it might be the sim bracket.
What should I do ? Should I try to flash another kdz or to install Lineage ? Or simply go to a phone service ?
Thank you very much for taking your time to read my post.

Tmobile and dual sim

Hello
I bought a used Tmobile LG wing and tried to put 2 of my SIM card inside.
The second card is not recognised at all.
Phone is unlocked
Is this a software issue and it can be cured or the phone has hardware limitation?
Thanks

Same try here with an unlocked T-Mobile LG WING, updated to Android 11 and also unlocked sim operator by update.
Watching some videos the dual sim is there, but are videos from India though, so no clue if this is a hardware limitation due region or the hardware for 2nd sim is there but it's software locked.
Did you (or someone else) find out why yours do not recognize the 2nd sim?
