but sim cards are not working on my device anymore.

SIM cards may be tied to device's IMEI, but never to device's SN.

[Q] HELP Original IMEI has lost :(

Dear All member xda...

Detail of broken list :
1. IMEI was FAKE ( i check on web that detected as Samsung Galaxy S3)
2. BT and Wifi MAC Address was 11.11.11.11.11.11
3. BT and Wifi can't turned ON always dimming
4. Serial Number was FAKE
5. IMEI CERTI : Fail
Now i has repair it but only problem number 2 and 4
I give to technician but same as before,,
My device was run on Android 4.4.2 and can make a call
Problem is :
1. Cannot turn on Wifi and BT(Always dimming) :crying:
2. No EFS Backup
3. IMEI still Fake
4. IMEI CERTI : Fail
Anyone can help me??
Need advice..
Sorry for my bad english..
Based upon claims your IMEI is fake, either the original IMEI was cloned and subsequently discovered, or the phone is counterfeit. I'd see about getting your money back, because Samsung won't touch it, and discussing methods to change the IMEI is forbidden here.

I won't to change imei,,just want to my original IMEI back..
it can be??
if can't i just want my wifi and BT can turn on,,
it can be??
once more,,what it's IMEI CERTI : Fail ????
Don't worry about the IMEI Cert. Mine says "N/A" yet the phone functions normally.
As to the IMEI itself, when you enter *#06# into the dialer, what is the result? Do you get a number, a number starting with 049, or a null response? If a number, does that match the number in the battery compartment?
Any other result than a number matching the number in the battery compartment requires the phone be serviced, which may not be cheap, assuming Samsung even touches the phone.
Bluetooth and WiFi may work again if you flash the firmware for your device through Odin. But this phone will never make calls until the IMEI issue is resolved, if it can be resolved.

IMEI result from *#06# it's not match with IMEI in the battery compartement..
I don't think to make IMEI match anymore,,i just wanna my BT and Wifi work again.
i was flash firmware hundred of time,,change modem too,,but nothing happen
disassembly and check hardware was too but nothing happen
anyone can help me?? please..
Send the device to Samsung for service. Especially if repeatedly flashing the firmware didn't fix the WiFi and Bluetooth. Be prepared to pay for the privilege.

Simunlock Problems

Hey there,
I got a I9505 that doesn't detect my simcard (if i put it in it still say pls insert simcard like there is none). so my guess was carrierlocked...
It also doesn't ask for an networkunlock code .. so i didn't wanted to buy a code on these websides because i didn't know where to enter the code.
Well I've tried the trick with the *#0011# and it doesn't go into the Service Menu.
The phone is on 5.0.1 could this be the problem ? Is there a way to downgrade?
Or do i have to falsh the modem in any way?
Till now i've just changed the FW with Odin to the DTB Version.
I'm kind of scared to try other things if I'm not sure what they do...
I'm really sorry if the solution is in a thread i havend found or just overlooked
thanks for your time and help
A properly working SIM lock would recognize the presence of the SIM card, and when you unlocked the phone, would prompt you to enter the unlock code. Therefore, a carrier lock is not the source of your problem. Unfortunately, yours is a hardware problem, and based upon your description, it's a motherboard failure, rather than a SIM card tray failure. It cannot be the SIM card tray because a SIM card tray failure would not ask you to insert the SIM. Instead you would have a circle with slash in the notification bar to the right.

Thank You for your help,
So in the mean time I successful downgraded to 4.4.2 (cyagogen)(and upgraded again) found a soulution to flash and access the modem so i could do the trick with *#0011#...but it's still not working.
I just don't to belive that its a hardware problem. Is there anyway of another software Simlock?
Because the Network Conectivity bar is showing 3 bars.
I got it (not so) cheap from ebay, so could it be that the imei is block in the network ?
Thanks agian for your help
IMEI could definitely be the cause of your problem, especially if you actually do have a signal.
It is showing 3bars but not the H for HSDPA but it also shows those bars if no sim is insert so...
The imei ist blocked ?
Guess there is no way to change it
Sent from my Nexus 4 using XDA Free mobile app
If no SIM card is inserted you wouldn't have any signal, but a missing SIM card indicator. This behavior confirms to me that you have a hardware problem of some sort. You need to have the device looked at, because software is unlikely to be the source of the problem.

SIM card not detected

I moved my T-Mobile SIM card from my Nexus 6 to my never used, eBay purchase, 6p. The 6p does not detect the SIM card. I reinserted it multiple times with no luck. I don't know if it matters that I installed TWRP, Nitrogen ROM and Franco kernel, without the SIM in the phone?
The phone is otherwise fully functional.
Any ideas on what might be going wrong? The package slip that came with the 6p states, "Tested for Key Functions, Ready for Resale". I've contacted the seller for advice.

Probably should of checked it out before loading a custom ROM. That being said if the ROM is 8.0 I don't think the first version of the update is compatible with T-Mobile.
"8.0.0 (OPR6.170623.013, Aug 2017, Not for TMO/USCC/Fi)"
You should maybe try a stock ROM first. Get nexus root kit. There is an option to revert the phone back to stock. Might help.
Just a shot in the dark. May also be locked to a region. Good luck though.
I reinstalled stock Oreo. Now, I'm only seeing "No Service". I don't know if this is of significance, but when I check Settings - > System - > About phone - > Status, SIM status everything is blank. At least the SIM was detected. I didn't realize when I installed stock Oreo it would wipe out my SDcard.
The vendor image is used with Nitrogen was opr5.170623.007.img.
And I suppose the sim works in other phones?
It's hard to say what is going on. May just be in backwards?
Aside from the bootloop and battery issues the 6p has been awesome as far as loading ROMs. You never have to replace the bootloader so even if you break the recovery it can be fixed easily. Not the same for my sapphire unfortunately.
Anyways I would first say it may be a physical issue, Especially if the sim says it's blank. Again, good luck.
I believe it's just Android 8 and not the phone. Go through any 6p Oreo thread and will find one person with this problem. Solutions that where posted fingerprint/pincode security off before flashing, no encryption on first boot and solution that worked for me complete wipe of phone flashing stock Oreo. I haven't heard any direct answer on what the cause is and I think the first 2 solutions worked for people because they did a clean flash of stock Android 8 anyways.
Yes, the SIM works fine in my Nexus 6. I noticed under SIM status, it lists "No signal".
I installed the factory Nougat ROM and still no service.
Under SIM status in Settings, Network is Unknown, Signal strength is 0, Cellular network type is Unknown and Service state is Out of Service.

Is your IMEI field blank too in Settings? If the phone does not have an IMEI, the device may have corrupted EFS partition(s). Boot the device to bootloader (fastboot mode) and select "Barcodes". Is your IMEI there? Is your model a H1511 (US model)?
Put a known working SIM in the phone from a different carrier (preferrably not an MVNO), If that doesn't work, since your phone is new (to you) there is no harm in fastboot formatting these 3 partitions (system, cache and userdata) and then using the Google script (batch file) that comes with a full factory image. Not a factory reset, not manually flashing a ROM. One other possible scenario is that if the phone was previously used on ProjectFi, you may need to contact Google and have your phone's IMEI de-registered. Hopefully you get it working and won't be forced to return the phone.

Barcodes shows IMEI present and model is H1511. I ran the script in the full factory image for Oreo and then tried the same with Nougat. I didn't reformat the partitions prior to flashing ROM. Is this important or does the factory image replace them anyways?
I don't have access to another carriers SIM card.

The script uses fastboot erase which does not format the partitions. Formatting returns partition information, any errors and in some cases corrections. You did not mention IMEI within settings, both under "SIM Status" and "IMEI information". If present in bootloader, but not in settings, this may further point to a SIM card. Until you try (borrow) another carrier's SIM for 5 minutes you won't know for sure. At the very least you could get TMo to provision you new SIM. They should not charge you for this, and it may change your situation. There are many threads on this very same topic. Maybe searching those would give you another idea.

According to Google, the phone was purchased from them. They do not know if the phone is financed, as this would cause the IMEI to be locked. I'll try the T-Mobile store next.
Spent an hour at T-Mobile. The sales rep was determined to fix it, but in the end was unsuccessful. The Ebay seller issued an RMA and I dropped off at the P.O.. Will try getting another.

No, I meant the the Google-Fi the MVNO (carrier) not finance. If the phone was activated on Fi, it will have to be de-registered on their end. You still did not reply about IMEI present or not in Settings>>Sim info?

When I went into Settings, the IMEI was present, but no carrier information. The phone recognized the SIM card, but that was all.
In the chat session with Google Support, I did ask about Google-Fi and she wrote that she was unable to provide any information on that. She said the only information she could provide is where the phone was purchased.
I came across the same issue. Just flash your vendor.img using flashfire, this will fix everything.
Another fix for the no sim is too turn off security pin lock and reboot the phone. I take no credit for this find just spreading the good word. ?

DO you have the global or the EAA version? If you have the global version you can try to flash full package of 1.1.4 to solve the issue.

How did you do the full flash? There is a tutorial in here where 1 command is false i think.
its flash fastboot xbl xbl.img but it should be fastboot flash xbl xbl.img.
Maybe thats what you need to repair but i think xbl image is about ram....

My imei is normal no problems
Maybe I can help with a solution: I have 2 SIMs and my mobile data suddenly stopped working one day. (It seems because the mobile carrier had technical issues in my area.) Now as I use mobile data only on SIM1 which I de-activated during the day in hope to get a connection back, I assume my preferred SIM changed (see Settings -> Network & Internet -> SIM Cards: Standard SIMs) to SIM2 for calls and mobile data. As the phone tried SIM2 for data but it is de-activeted there, both networks had a small "!" near the radio indicator. After settings the preferred SIM back to SIM1, everything is working fine again.

The problem is that the cell phone doesn't recognize any chip, so I can't open the sim card options
Hello i have also updated to 1.1.4 and after around a month it is also not recognizing my sim card. The sim card works on any other phone. I have tried rebooting, soft restarting, resetting all network options, I even changed the sim at the store. Nothing has fixed my issue. My last resort is factory reset.
Has anyone found a solution?
