Hi there,I had a problem makes me quiet confused. Recently I did buy previously used galaxy s7 edge.The phone come to me as new condition.First I notice missing label on the box where is says serial number,imei,bar code etc...Only other label on the box says europien sim only.Switch on the phone and everything seems to be ok,until I did not put in my sim card. Phone did recognize sim card and network provider but was unable to connect to network.Try with few more sim cards from different country's and network provider but the result was the same.Here comes the funny part.In the phone settings>about the phone there is a serial number and imei number.Both numbers don't match the type of the phone.Even the imei number.On the internet under this imei I find completely different phone.Model of this phone shows as 935fd.This sopostu be a dual sim but it's not.I do have this option for the second sim inside the phones settings but there is no way how to put the second sim in to the phone.Only one sim fit there and one memory card.Root count one.Previous owner maybe somehow manage to flash different model software,or something.What I will like to know if there is a way to fix it.Bring back the phone to it's original condition so I can used for the phone calls also.Thakns for any future respond.Hopefully I make my self clear about the issue I got

Hi all. Just after a little help if possible.
Bought a 2nd hand S2 and was told it was locked to Virgin, before I bought it I made sure I saw the buyer make a call with the Virgin SIM on the phone.
I downgraded from ICS to 2.3.5, rooted the phone and used unlock tool from Market to unlock the phone. Tried several SIM cards in the phone, but I cannot connect to any mobile networks. In Phone Status, it shows phone number, signal strength etc but when I try and make a call is shows ‘Not Registered on Network’
I went out and bought a PAYG Virgin SIM card as I thought the unlock may not have worked correctly and exact same thing happens. Put the Virgin SIM in my unlocked HTC Desire and works fine. So, its deffo the phone that has the problem. I checked the IMEI number online to see if it had been blocked but it looks ok.
Any thoughts??
Thanks in advance.
Hi
A few things to check/try -
Does the IMEI number displayed by typing *#06# into the dialer match the IMEI number on the back of the phone (Under the battery)?
When you put a sim card in (other than Virgin) do you get a message from the phone asking for a network unlock code?
Does the network name of the Sim card appear in the status bar?
Which app did you use to unlock the phone? I've used Galaxy_S unlocker several times without any issue. (I install a ginger bread rom first, then insecure kernel, then root, then run Galaxy_S Unlock)

Check ur imei no dial *#06#
verify that imei no with the one beneath ur battery
if it same then try flashing the stock rom again and root it and try unlocking again using the unlock soft from play store
Yes, the IMEI number matches so no problem there. Have been onto several free IMEI check sites to see if the IMEI number is blocked and it shows as not being blocked. How reliable these sites are I do not know...
No, no unlock message comes on. However, I locked the phone again when rooted and put the Virgin SIM in, which it should be locked to so should work, and I got a SIM unlock message? So, when the phone is locked, it does ask for unlock code, when unlocked using the app, lock code doesn't appear.
I do not get the name of the network in the status bar. When I look at the phones status, it does show a signal strength, and I do sometimes get signal bars but when I try and use the phone I get 'Not registered on network'
I used Galaxy_S app and did everything that you have done!
Have tried flashing stock rom, rooting and unlocking and nothing seems to work.
Worried that I may have bought a nice, expensive media player...
If your IMEI matches up with the one under the battery then I really don't know why you can't get a signal. Maybe someone else on here will give you some better advise. It sounds to me like you did everything right. The obvious thing would be if the phone is on the blacklist (stolen phone, or reported as stolen, 2 different things!). I wasn't aware of any sites that can tell you if the phone is reported as stolen so can't comment on how accurate they are.
Hope you get it sorted, it's the best phone out there at the moment so would be a shame if you can't make calls on it.
have you tried with diferent modem? or diferent rom?? or both at the same time?
for the modem try KI3 or KI4, seems to work pretty fine for almost everyone..
have you tried
hi have you tried going to
settings>wireless and network>mobile network>network operators
and checking the settings in there are set to autoselect network.
if this does'nt work +1 for all posts below.
hope it does.
also not sure but i think sim lock is set in security settings and the pasword for unlocking is stored on the sim that password was put on. anyone feel free to correct if this statement is wrong. many thanks

>> about device

M Phone number is showing as 000000000000
any ideas how to change this?
I think it's carrier dependant, can u tell us on what network you are? I'm not 100% sure though
all the s3's I've seen don't show it in Lebanon
I'm on t-mobile uk which is now showing as ee, (everything everywhere)
its a SIM card thing I put my SIM in wife's old iPhone and now on gs3 shows number

Yes it's written on SIM card, some roms can't write it down on the card, the solution if you absolutely want this is to put your card in an old/another phone.
With my previous phone the number wasn't readable, now I have it.
Thanks for the replies, its not that important, but i may swap the sim over sometime .....
thanks
Hi
I have the same problem, I did put my sim in a different phone and edited the number but it still shows the wrong one in my phone. Any solutions?
Sent from my GT-I9305
First of all, I'm in the US. I bought the Samsung Galaxy S II GT-I9100 (I'm in the right forum, yes?) off of ebay.
From what I remember, when I received it, it had some weird ROM that I had never heard of and can't remember the name of, along with clockworkmod recovery already installed.
I put cyanogenmod 9.1.0 on it via: [cyanogenmod's site, model galaxys2 cm9.1.0] (I can't post links yet, so I had to remove all of them).
I was using it mainly for development for a while, so I never tried to activate it on a network using a sim card, but recently I tried to do that with StraightTalk (using an AT&T sim). Nothing happened. I rebooted my phone multiple times, took the battery out, reseated the sim card multiple times, etc. Nothing is any different than before I put the sim card in (except the messages about "No sim card installed" have gone away). And in the settings, it shows that it can read the phone number from the sim. I actually talked to their support for a while and they couldn't figure out what was wrong. I tried the sim in 2 other phones and it works fine on those.
I thought maybe the problem was cyanogenmod 9, so I tried installing cyanogenmod 10 nightlies made specifically for this model from: [cyanogen's site, model i9100 cm 10 nightlies] . Same thing with that. No network connection, emergency call only, etc. I've gone through the settings, trying to change things throughout. I've tried to force-connect to AT&T's network via the Mobile network settings -> Network operators menu, but it just says it can't connect to that network. When I tried to connect to TMobile's network, it said this sim card did not allow a connection to that network.
I wanted to double check to make sure the sim was actually unlocked, but none of the magic codes ( [cduu wordpress galaxy s2 secret codes] ) work except to display the IMEI. I've checked a couple online databases to make sure my IMEI is not blacklisted, and both said it was not blacklisted.
Getting pretty much nowhere, I wanted to return it to stock, but when I read up on it, I could not figure out what to do in order to do that. I'm not very experienced with the GS II; my personal phone is the galaxy nexus. After reading up on it, there's about 100 different versions of "stock" for this phone, depending upon what country/language. I don't know where this phone is from, but the only booklet it came with was in French.
I did find the sammobile released firmware versions for jelly bean and ice cream sandwich (I9100XXLSJ_I9100OXXLS1_OXX.zip and I9100XXLPH.zip) from [sammobile's site] . I don't even know if these are technically stock though. The only one I tried to flash was the ice cream sandwich one; the jelly bean one is still downloading. When I tried to flash the ice cream sandwich one using Odin3 v1.85, it just failed. Didn't harm any of the software that was on there, so I'm guessing it found that it wasn't the right version for my hardware?
So after all this work, I'm coming up empty.
Is there anything else I can do to try to troubleshoot why I have no cell network connection at all?
Should I try to flash back to stock and if so, can anyone tell me what english-language version of firmware/software I have to flash/install to my phone to get it back to stock?
Can I provide any more information to help?
Thanks for the time.
Since you have verified that the sim card is working properly.
Then the issue is with the phone,did you check with the provider if the imei of the phone is valid or not. It maybe a blocked device because it was reported lost or stolen previously.

I only checked in a couple online databases and they both said it was not blacklisted. I found the IMEI issuer at imei-number .com though, and it says it was issued by BABT (British Approvals Board of Telecommunications). Is that who I would contact? I don't know how I would contact them and get a response. Other than that I don't know what carrier the phone was used under before.
If it is not blacklisted
It maybe a hardware issue in that one pins for the sim card is not making contact properly. You may need to take the phone apart to see if there is an issue with sim connection.
Would it be able to read its phone number from the sim if a pin wasn't making connection?
Under About Phone -> Status, Network is Unknown, Signal strength is -111 dBm 1 asu, Mobile network type is HSDPA:9, and the phone number is listed correctly.
Oh, one thing I didn't mention is that the device ID from "adb devices" shows up as 0123456789ABCDEF.
And I just noticed in the About Phone -> Status menu, the Serial number is "unknown." Is there something in my ROM or something that is blocking or has erased the serial number or device ID?
Any ideas?
I'm probably going to have to buy a new phone for development today, so if anyone had something to try before then, it'd be really appreciated.
Hi,
Three months after getting this OX+ I get round to using it and put a new sim in it only to find there is no signal and the IMEI number will not display, it is "unknown".
I have just paid for an IMEI report which shows it`s identity and history is legit and the numbers tie-up with packaging and sim card tray and phone serial number. The report also says the phone has not been modified/rooted. The boot loader is locked. Is this a dead duck or are there measures I can take to restore the original IMEI by rooting/clearing cache etc?
Hello to forum and sorry for my English.
I recently bought an S9 Plus Dual Sim. The phone has a strange problem. It can only recognize the one of 2 sim cards ( sim number 1) and has signal but whenever i am going to make a call, gives me the error :“Not registered on network”.
The sim card in the second place of sim tray, is not reading by phone.
The phone has only one IMEI in the settings and when i dial the code *#06#.
The back cover of the phone has 2 IMEI and the one is the same as this i can read in the settings.
I installed the confirmation firmware and i dial up again the *#06# with the same results.
I made a call to official Samsung and the phone is clean and unlocked.
I am so comfused.
Can anyone expain me what is the problem ?
It's very strange... But you can try to send it to warranty service and hope that they will substitute it
