I have the international GS3 and got it unlocked with a code and it worked fine on Orange network, while the phone is on Three, so then i flashed Omega 7 and rooted and it will no longer detect the Orange network, its just a circle with a line through on the status bar.
I thought maybe it wiped the unlocked but checked and it still says the phone is unlocked so i thought i would test and put back in the Three sim and it worked fine and then i had a old pay as you go o2 network sim and put that it and it gets a signal and the option to top up.
So i thought maybe the sim is faulty, and put it into my iPhone 4S and it gets signal and reads it, i followed the instructions and revered back to Stock to see if that fixed it but still the same problem.
Anyone have any ideas why or how to fix this?
Check your IMEI number

If your phone lost it's IMEI number, it will revert back to a default-number.
Some networks still accept the phone with that number but most don't.
Just checked with the three card in usig *#06# and a imei comes up so it can't be that or should I t do it with the not working orange card in?

IMEI is your device ID. Does it match the IMEI-number on the box or under the battery of your phone?
If not, you're on a generic one.
Yep its the same as the one on the box. I hm

Try another Sim and also check the Sim is locked into the receptacle properly.

I've tried two other network Sims and both work as well as the orange Sim works in my I phone.
Weird thing is when the orange sim. Is in the phone it shows the apn correct for orange but I just get the circle with line through where the signal should be.

CSC includes Orange ????
Network settings entered manually if not .

Your SIM might be locked to your iPhone's IMEI or does it work in other devices?
I've only heard a few reports of such practices and none so far with Orange (regardless of country)
As above....check apn settings
I checked apn under three and the orange wasn't there. I put in orange sim and three apn is gone and orange are there and the correct settings but still the same stop sign looking symbol where network signal should be.
Not sure what csc is.
It worked before in the g3 before I flashed to the omega rom so don't think it could be locked to a phone

phone's imei doesnt match true imei
hello,
what does it mean that the imei given by the phone doesnt match the original imei written on the back of the phone?
If for some reason the rom you put on your phone screws up the IMEI and replaces it with a generic IMEI you now have a different IMEI than before. This was happening with the SGS2's a while back when flashing certain roms... Was fixed pretty fast and haven't heard about it happening again BUT there's always a chance and no guarantees...
Is there anyway to fix it back without any backups?
Sent from my GT-I9300 using xda app-developers app
It's actually happening quite a lot with the S3, especially the US-versions
Some people have claimed it to have been fixed when flashing a Stock ROM through Odin, but should it not be fixed then you'll need to have it repaired by Samsung.

There have been a few users claiming to have fixed it without Efs backups in the sgs2 forum (from fading memory). Have a search there, as any method will /should be similar
Worth a search/try, or as posted above, will need to return to Samsung

Use "k-tool" to backup your imei and keep it in a safe place(upload to dropbox and PC) and use APN manager to backup apn settings. Btw is a brilliant app to have when traveling
Edit:u can recover your missing imei nr. But be sure to have the original efs folder,especially NV-data.bin most not have tampered with

how can i flashing a stock rom ?

Hi there guys, i have quite a peculiar problem and i tried searching the threads but to no avail.
I have an international RAZR XT910, i got it used, and as far as I know, it is sim unlocked, because i am already using a local sim on it (i live in the Philippines btw) and no local carrier offers this phone, thus the assumption that it is already sim unlocked.
However earlier today, when i tried to pop in another local carrier's sim card, i cant get any signal, and i dont even get the "sim card invalid" screen, just won't get signal at all.
I know the sim card is good since i tried using 2 different ones, but both wont get a signal.
When i put back my original sim card the phone works normal and gets signal.
My question really is, how do i make sure the phone is unlocked? Coz i know with samsungs there are codes you can use.
I have stock ics on system 1 and PA3.8 on system 2 using BMM btw, if that matters.
Hope to get a response. Thanks guys.

How old is that second sim card?
I've had that problem when I bought this phone,my sim was10 years old,it was functional in some older phones but not in this one,because of old chip,so I had to replace it with new one.

I just did, we have 3 carriers here in my country. I tried the other 2 and both have the same symptoms, no signal. :banghead:
I don't understand why this is fhe case, bexause i am sure that the carrier which works on the phone never released this phone, thus the phone being sim locked to this network is unlikely.
Isn't there a way to check the lock status of the phone?

Hello, I just bought samsung galaxy s3 and tryed to put in sim card, but it doesn't recognize it. I tryed to do factory reset lot of times but it doesn't helped it still writting no sim card. I tryed to put in my friends card who is in other network, so I think its not a sim slot problem. First think - it locked. Today I went to the salon of my operator and they sayed that my phone is not locked or black listed, so maybe somebody knows the solution for it ?

Proble might be hardware: sim slot or sim card. Does your sim work on other phones? Do other sims work on your phone?
If its software, a fresh firmware flash with wipes should fix it.
I tryed to put sim to my brothers galaxy s2 and it worked, and we tryed to put other network sim to my phone and its too worked, but sim with the same carier like my didn't worked, if its a software can u give me link where I can find tutorial how to fix it ?

I've known some weird bug to happen (1 in a million or more) where a specific sim won't work on a specific phone, a friend working for movistar had that happen. Don't know why, just that sim won't work in that phone. They had to make a duplicate of the sim with a different format.
Check with your carrier to see if a different sim might work. And make sure its not a problem with the phone being locked.
Can you tell us. Is the phone 2nd hand or brand new?
I was thinking that if it is 2nd hand, maybe the previous owner flashed Custom Roms and may have damaged the 'EFS partition' when they flashed Stock firmware back onto the device before selling to you.
No, if EFS is damaged then device wouldn't log into any network.
Try to repair your device with Kies if you don't know how to use Odin:
http://forum.xda-developers.com/showthread.php?t=2088809
If it doesn't help visit your carriers store and get your SIM changed.
I tryed to put in maybe 4 cards with the same carrier and it didn't worked, yes phone is for 2nd hands :/

Now, when you say it doesn't recognize the sim cards, do you get a "sim not inserted" message?
Or does it recognize the sim but won't allow making calls or connecting to mobile data?
You say with different carrier (your friends sim card) it works. But with your sim card and others from the same carrier it doesn't work. That sounds just like a network locked phone.

When I turning it on it loading about minute and in that place where is network bars is pic like phone blocked I think, but after loading it shows me a perfect connection, but in my task bar writting "No SIM" and under it with lower letter "Insert SIM card". On the lock screen is too writting "No SIM card - Emergency calls only"
I know that it's sounds like network locked, but I was gone to the salon operator and they sayed me that phone is not locked, but I did not understand, or only to their network, or general. Where can check it ?

This totally looks like a sim locked phone.
What you already know is that the phone works with your brother's sim card, so the phone works with your brother's carrier. You know it doesn't work with your sim card or any other sim card of your carrier.
But you are still not sure if it is a simlock.
Just check with a sim card from another different carrier (one that is not your carrier, nor your brother's carrier). If the phone is simlocked it shouldn't work with that 3rd carrier.

I recently purchased a note 3 and I didn't have a sprint sim for it. I ordered one and inserted it but I still get the notification "No SIM". I've rebooted the phone and checked to make sure the SIM Card is in correctly. What do I do.

Either your SIM is bad or your reader may be faulty. I know sellers like to sell phones without the SIM in it to hide a failed SIM reader.

I'm fairly sure the SIM Card Reader is functional because I put a Verizon sim in originally to try to remove the notification. I will switch the Sims for my note 3 and 2. To find out if my sprint sim is faulty. I'm doubtful but best to check

OK just checked the sprint sim card is functional as I get a non Verizon sim notification in my note 2 and when I put the Verizon sim in the note 3 I get invalid sim so this means the sim reader is functional on the note 3 and the sprint sim card is usable. What's going on then

I'd still try another Sprint SIM. When you get the replacement one MAKE SURE TO TELL THEM IT'S FOR A NOTE 3!!! As far as I know, there's different SIM cards for different devices. A SIM from an iphone 4s won't work in a Note 3.

I can give you the link for the sim I got. As far as I know it's the only sprint sim out there that I could find. Would It be possible to flash the note 3 to Verizon, At&t, or T mobile. If it would be easier than getting a new sim.

As far as I know, it doesn't matter. I could be wrong. But from my experience the SIM model number does matter. The model number varies amongst the various Sprint devices and I recall what worked for one phone didn't work for another.

So wait....you're trying to flash? It's unable to be unlocked to GSM. If you flash the device you don't need the SIM. The SIM is ONLY for 4g LTE. If you flash you won't get LTE, and therefore you don't need the SIM and anyone who tells you otherwise doesn't know how to flash the baseband.

Huh?
You lost me. I just want the notification gone. I'm trying to use the note 3 as a media device not a phone as of now. If I could flash it might remove my error. I don't know if it's even possible. Not worried about the LTE till late when I may or may not use the note 3 as a phone. Data charges get me. But if there's a way to fix the sim issue with no flash that would be ideal. But if not its alright I can probably flash or try order yet another sim. Or try to find another solution.

I think someone found out how to remove the no sim notification by editing something in the build.prop. But honestly, it doesn't even do anything. You can still use the phone on Wi-Fi and you can get it flashed to use talk/text/mms/3g.

You'd need to root the phone and get some kind of file explorer. It's not that hard. The most difficult part will be finding what to edit/add to the build.prop file.
Throw the Sprint sim in the trash...or burn it.

I had a problem with the SIM card from a Note 3 that I bought on Swappa. My problem was that my phone would not switch to 4G LTE. It gave me some EHRPD error and occasionally a no SIM card found error.
The way I fixed this is I wrote down the serial number off the card itself then contacted Sprint via chat support. The number on the card was different than the number Sprint had assigned to my phone. They changed the number to the number of the card I had, rebooted my phone and the problem was fixed. Now I have 4G LTE and no longer get a no SIM card detected error.
I suggest writing down the number from your card, contact Sprint via chat and have them change the number of your card to your phone. That might fix it for you. How this helps!
Why not just take a trip to the Sprint store. They should be able to fix your issue.
I recently picked up an unlocked verizon s9+. I have no service at all. I flashed the u1 firmware thinking that would fix the problem no luck. I put my sim in and it reset to configure for the sim still no service. My s7 edge has 2 bars and my wife's s8 has 3 so its not that I'm in a hole. Any help would be greatly appreciated.

Are phone calls and texts working? Have you checked the IMEI of the device to see if the phone has been blacklisted? Verizon would probably tell you, or there are various websites on the internet.
Other than that, what carrier Sim are you using in the phone, and have you made sure that the APN got set up properly? Hope you get it working!

That's good you got your money back. Probably somebody reported the phone lost or stolen or defaulted on the payments and now the IMEI is blacklisted. That's my guess anyway.

There are some okay vendors on eBay, I got mine from a mostly accurate vendor, phone was new and unlocked but originally from Verizon even though it was advertised as factory unlocked. Luckily I was able to flash it over and turn it into a perfect deal for myself. Good luck, and pop your sim into the phone first if you buy in person.
Picked up another for a descent price. Getting better signal than the 7 edge. Took your advice and checked real good.
