Hi all. I was out of my country and used another sim card for these days. After i returned , when i tried to use my own sim card my phone doesn't recognize it. The very same sim card works in another phone. Another sim card works in my phone but my sim card doesnt work in my own phone. I tried factory reset, it didnt work. Then i flash stock rom, again it didnt work. Any ideas ? Thanks in advance.
I had this happen to me once. The only way I fixed it was to get a good new sim card.
Not really sure what caused it.

Help!
I was rooted 4.1.1 and flashed latest 4.1.2 Czech stock ROM via Mobile ODIN. Everything seemed to went fine except, wifi seems to work, but I have no SIM detected. I tried pulling the battery out but no go. What went wrong?
Any help appreciated!!!

Did you try to pull SIM out? Use different SIM to test.

I didn't since it is pretty hard to take it out being micro SIM, and I have no other micro SIM to test (only normal sized mini SIM). I didn't open the phone or done anything to the SIM so I have no reason to suspect it being moved or such. Probably something to do with EFS folder from what I read.
When I dial *#06# it says nul/nul (should display IMEI).
PLZ Help!!!!

Does your sim card come out when you pull the battery?
Nope, I don't have custom recovery because of triangle !#[email protected]!
I noticed another thing, it reports Baseband: unknown
I've had the same thing, flashed new custom recovery version and ended up with broken sim-card...

We just went to a service center of our telecom operator to change the sim-card and the new one works fine.
I tested the original if it could be broken by using another sim-card, just to be sure, but it was true what i expected
How can flashing software affect the sim-card that seems hardware to me...?
Is there any possibility that the sim-card gets wiped or something?
No, it doesn't seem to be SIM card - I can't try another card in my Note II because it is the only phone I have with MICRO card. But my card from Note II works just fine in old Sony-Ericsson....
BTW, took the SIM card out and back and still no go. It has no BASEBAND.
I wonder... when I bought the phone, it's 1st language was GERMAN. It could be german import. It wasn't CZECH. Now I've flashed Czech ROM. Could that have any impact?
Managed to "repair" it. Just flashed the SAME ROM with Odin from PC, and my IMEI reappeared.... HAPPY!!!
Thanx 4 help!
Make efs backup.

Will have to Thanx! Lost my root now, but important that it works
Hi all,
I have a Huawei P6 in which I tried to change my SIM. However when I put the new SIM in it was not recognized and my Micro SD card is also not recognized now. I have tried factory resetting, the SIM works as I have tried it in another phone. Does anyone have any ideas on how I might be able to fix this?
Thanks

Does it work when you insert your old sim again? If yes, I guess your phone is sim-locked.
Anyway, your sd-card should always work... so why it doesn't...

I have found that the old SD Card was corrupt however I have tried my old SIM Card again and it still isn't working. I bought the phone unlocked so as far as I'm aware it shouldn't be locked to a network.
Good day! I just want to ask if anyone has an idea of how to solve a weird and sudden problem that happened to my phone a few days ago.
I was running Cyanogenmod R16 with Xcelerate kernel.
I use two SIM cards on my phone, but I do not use the first slot all the time, so when I'm not using it, I regularly disable it through the SIM card settings, and enable it only when I need it.
What happened is, when I tried to enable it, suddenly both my SIM card slots could not be recognized (The SIM card settings could not be accessed; and error says: "SIM card info not available. Menu cannot be accessed"). In the lockscreen, it says: "INVALID CARD." for both SIMs.
I tried both restoring a backup and going back to stock MIUI, but still, the problem was there; none of the SIMs could be recognized (I tried using other SIM cards too.)
My IMEI's for both SIM slots are fine.
I've looked up on other forums, but I haven't found any others with a similar problem on the Redmi 1S.
If anyone knows what I need to do to fix this, I need your help. Thank you very much.
Have you tried both sim in other phone..?
If yes,and both working then should be problem with your imei!

Yes, I've tried both SIM's on another phone, and they work fine.
Since my phone still shows both IMEI's when I look for it, I assumed that there's no problem with them. What are possible problems that concern IMEI's? So that I can look up on general IMEI problems.
Thank you very much!
May be this can help friend

Thanks for the reference. Backed up my IMEI and Restored it right after, but still no change. Still, thanks!
EDIT: I've already tried two newly bought SIM cards, and the problem is still present.
Was this solved? Happening to me right now..
Happening to me too... Unsolved
For me just blowing in the sim slot & reboot fixed after few times..
if you have TWRP backup your modem & efs partition, just restore it via twrp. it worked for me
Hello,
I have a similar problem.
SIM2 is not recognized at all. I can use SIM1 only.
Tried to switch the SIM cards and still SIM2 is not recognized.
Both SIM cards are working great on other phones.
Is it OS related issue?
I've got same problem. Try to clean the sim metal contacts carefully and gently with an alcohol and qtip or tissue. It solved my problem.

Hi guys,
bought a LG G4 and used it with SIM card from Vodafone without any issues.
Now i've tried a SIM from another carrier and phone doesn't reconizes it, thous i've tried this SIM in other phones and it works ok.
What can be the problem? Cheers
Don't know. Had a similar problem. Phone would NOT recognize SIM card after reboot. Needed to reboot 1, 3 or even 4 times! I swear it stopped BEFORE 10C update. Nevertheless I do NOT have this issue anymore despite NOT changing a thing. Same SIM Card, same phone.
Try rebooting. Try updating to 10c

I just bought my brand new lg G4 unlocked but it doesn't read my SIM card . Pls help
I have an LG G4 with the SIM card in it reboots on its own with the SIM card out it does not reboot but I can use all of my apps and do a WiFi call through Facebook Messenger or Whatsapp. Anyone have that problem?
Hi, I buyed the One Plus 3, but when it arrived i see that it need an nano Sim card, proceed to cut my old card and insert on OP3, the card don't show network signal, i thinked it was from being cut, so i proceed to buy a new card, i inserted the new card and nothing no signal, it detects the carrier ID but never get's network signal, if i manualy search networks it don't any carrier, I Tried with anothers Sim cards and no one can't get signal on OP3.
All the cards are working on my before One Plus One, i tried factory reset, i contacted the provider and the problem is not with the sim card.
Is there anyway to share the modem or something like that so i can fix this?, i even try twrp recovery, and flash the original Oxygen Signed zip.
