[Q] Galaxy S2 Won't Register on Netowrk - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
I'll explain my situation. I had a work supplied HTC Sensation. The most god-awful handset known to mankind... except the iPhone. I digress. We are on Vodafone UK. When it came to renewing the work phones I was given an "upgrade" iPhone 5s. Long story short, I'm not using it. I have a Samsung Galaxy S2 which was on T-Mobile. I was given it and I thought I'd give it a go as it has to be better than the HTC Sensation.
Firstly I put in my Vodafone SIM. As I expected it didn't work. I have checked the IMEI number and it hasn't been blacklisted. So I thought I'd unlock the phone and root it. I followed the advice in this thread:
http://forum.xda-developers.com/showthread.php?t=2365701
After the first go of installing Jellybean which is what was on there initially I got to the end, rooted it and it wouldn't unlock using the method given. The method goes on to say that it works with ICS. So, I went through it again and installed ICS. Rooted it. Ran the unlock. Still locked.
Question 1: Is SIM lock the same thing as Network Lock?
At the moment, I have the stock ROM from the above thread for ICS installed. 4.0.3 I think it is. If I put my Vodafone UK SIM in this phone, when I try to make a call it says "Not registered on network". Tried following lots of advice in different threads. None worked. I thought, maybe that it can't register on the network as I am boosting my signal through a Sure Signal. I tried going to a place where I know I would normally get signal and tried doing it there. Still no luck. I keep digging and I come across the DEBUG MENU on the device:
http://forum.xda-developers.com/showthread.php?t=1882796&page=4
It suggests this:
dial "*#197328640#" to enter debug menu
click "6 [common]"
click "6 [nv rebuild]"
click "2 [erases three partition!]"
Except in the 3rd option there is no menu option 2. I have kept digging and then came across the "Personalizatiob Status" (http://forum.xda-developers.com/showthread.php?t=740167) and it shows this:
Network Lock
[OFF]
Network Subnet Lock
[OFF]
SP Lock
[OFF]
CP Lock
[OFF]
Please note that during all this my Vodafone SIM is NOT in this phone. It is in the HTC Sensation and is working just fine.
Question 2: Do I have to have my SIM in the phone when I do all this?
Question 3: How can I get this phone to register on the network with my existing Vodafone UK SIM that is working just fine?
I've tried the Galaxy S2 Unlock apps on the market store. The unlock code and unfreeze code show gibberish.
What am I missing? I don't actually care for using the stock Samsung ROMs because the phone is way out of warranty anyway. I just want to avoid having to use the iPhone I've been given.
Any advice welcome.

Any advice from anyone?
Cheers.

Nope, haven't tried that one. I will give it a go later on this evening. I've tried a couple of unlockers that have been recommended in other threads and neither have worked. I'll keep you posted.
Any thoughts on the other questions I had on the original post?
With regards to the iPhone, I think I'd rather stick with the HTC Sensation despite its multiple daily crashes/restarts and almost constant need for recharging.

I tried the app and it said everything was unlocked except for CSC Lock. Now, I did some reading on that lock and that seems to be a geographic lock applied by Samsung. As this phone was bought in the UK and I'm putting a UK sim in it, then this won't affect me because both the original TMobile SIM and my Vodafone SIM are UK.
It said my unlock code was 00000000. I doubt it is that, but on the slim chance it is, where do I even put the unlock code in?

Attached is a screenshot of the lock status from GalaxSim by Spocky.
It now shows everything is unlocked. Any ideas?
I can see the sim operator is listed as Vodafone and the registered operator is O2 according to that. Weird as it had a working T-Mobile sim in it prior to my getting it.
Thanks.

Any further ideas? There has to be something I've missed.

Well, I have still not managed to find out why this phone won't connect to the network. Sadly my old HTC Sensation has pretty much now become unusable and I've had no choice but to start using the iPhone provided by my work as I've not been successful in getting the S2 up and running.
I cannot believe just how bad the iPhone is. I've always said they were rubbish from day one despite having never owned one. Now I have one, I can justifiably say that I was correct in that they are dreadful things, however, I didn't quite realise just how rubbish they really are. Now I know.

[Q] Unlocked Vibrant could be locked again?

Hm, you might be onto something.
I had unlocked my Vibrant using an AT&T SIM a few weeks ago (code provided by T-Mobile), but when I was on vacation in Central America last week, I tried a local SIM and it asked me for an unlock code again.
I never did bother trying to unlock it again, but it was kind of weird. Will test it again with AT&T when I get a chance.
I travel to canada once a week and switch my Tmobile sim to a rogers sim. Has been working for almost 2 months now. Tmobile provided code.
Just re-enter your orig unlock code again
I had similar issues some time ago and posted a question about it but no one responded. I have sinced re-flashed the stock rom again (2nd time) and I have not seen the issue again. It would usually pop up after having to force reboot the phone or do a battery pull after an app hung. I was beginning to think it was related to being rooted and an issue with the mount rw-read only. The first thing I did after the re-flash was to unlock, then did the root etc. It has not come back. One possibly related thing is that sometimes when I have to reboot, it shows missed called after it boots. These are calls that were from a day or 2 before. Its almost like some info isn't being "committed" when a force reboot is done.
Fortunatly it seems that it is just a matter of entering teh unlock code again. Just really strange though...I have always been told that once it is unlocked, it is always unlocked.
Well, it happened again yesterday. Phone was acting wierd, lagging, apps hanging, so I rebooted and got the sim unlock screen again. Entered the code and it unlocked ok.
Very annoying....
My previous Vibrant that I had unlocked re-locked itself somehow as well. I noticed this after I had re-flashed the JFD firmware with ODIN. I popped my AT&T sim and was prompted for the unlock code (again). Which I then entered but unfortunately it didn't take. What's up with that?
I checked my nv_data.bin once again and the code was still the same. I could never get the thing to unlock again though either with the unlock or unfreeze code. It didn't appear to be frozen either; if it was it didn't indicate that.
While flashing via ODIN I never even checked the box related to "efs". I just reloaded the JFD/stock firmware which worked fine. I can't explain it. All I know is I haven't unlocked this new phone yet. I have the code but I will worry about it when the time is come that I need another network to use.
I did notice on the samfirmware.com site they mention to "check your simlock" before flashing a new firmware. Anyone know what that means other than something obvious?
This just happened for the second time to me on two different vibrants from TMO. Is the consensus that the phone needs to be reflashed?
FYI, I have flashed mine twice back to the stock rom and it continues to happen. Also, I opened a ticket with Samsung and even got an RMA to send it in so they could "reflash it". I never sent it in because I knew that would not fix it.
Again, this seems to happen when the phone starts to lag or apps start to hang and I reboot. This has got to be related. I wonder if anyone has had it re-lock while running a lag fix? FYI, Mine is the stock rom rooted and thats it. I wonder if this is only happening on rooted phones?
It really scares me that there is at least one account of it not unlocking with the correct code after it re-locks.
Really would like to find out a solution for this.
I've read that this happens with a lot of Samsung phones, they'll just randomly lock.
Sometimes it appears to make sense (after a ROM flash .... even an official one), sometimes it doesn't. Sometimes it'll only unlock for the SIM you put in, but when you put another in, it'll lock again.
Just make sure you keep your code & have it ready to enter at any given time. Seems to be a Samsung glitch (like the many others we have to deal with).
Yeah same here. When my old vibrant relocked i could never get it unlocked again with the same code. I also highly recommend if your phone is rooted to make a backup copy of /efs which is where that nvram data is stored.
Surprised Here Too!
I went out of my way to go to an AT&T store. Then I read a thread here about proving Vibrants are unlocked. Pissed! Now you're telling me that it may never un-lock again?
"Open the dialer and key in *#7465625#. For an UNLOCKED Vibrant you should get the following result: Network Lock [OFF], Network Subset Lock [OFF], SP Lock [OFF] CP Lock [OFF], press OK to exit that menu"

They don't come unlocked, you have to unlock them.
I unlocked my vibrant & what you wrote above is what I see.

[Q] How do I unlock my phone?

I've got the Gingerbread bootloader, Passion ICS, and I'm (obviously) rooted... Everything on here that I've searched said I should be unlocked, but when I gave the Vibrant to my AT&T bound friend, it doesn't detect her network (or even that the sim card is in the phone, for that matter.
The phone works fine with T-Mobile, and her sim card works alright in my G2X, but could someone clarify what's going on here?
If you call or email T-Mobile they should send you the unlock code.
There's other apps/hacks to unlock bit of a hassle but T-Mobile sent unlock for me quick. Bought phone used too, they don't seem to care much about T-Mobile account or not.

You see, my other AT&T friend had it while it was rooted with Trigger rom on it, and it worked fine for him. I'm thinking it's the bootloader that re-locked it, but I may not know what the hell I'm talking about.

Still didn't work.
--Disregard. How do I check if it's unlocked? *#SIMLOCK# doesn't bring up anything.
Rooting, GB bootloader and ROMs, shoudl have no impact on whether or not you are unlocked, IIRC correctly. Use the Galaxy S Unlock from the market. Run it (correctly) and don't freak out about the black screen. It's only like that for less than a minute. Once it is done and rebooted, let your phone settle down.
Go into your dialer and punch in these *#7465625#
It will give 4 items. You want the top (Network Lock) to be OFF. If it is, then you are unlocked.
Don't rule out the fact that your friends ATT card might be bad or s/he might need a new one.
1. Yes, I have run said app correctly. The first time, I didn't have busybox, but I ran it again with it.
2. *#SIMLOCK# is the same as what you typed, it doesn't bring up the menu, though.
3. Her SIM isn't bad, if you read the OP, you'd know that it works in my G2X (what I didn't mention is that she has her own phone which it works in completely fine, as well.
Mostly, what I want to know now is why *#SIMLOCK# does nothing.
Strange. There is a manual way to unlock it using ADB, but it is pretty intricate with high probability of errors.
I would suggest just calling T-Mo and getting them to give you the unlock code, especially if the apps didn't work for you.
Let me know if you want me to give you the link to the manual way to unlock. Will take me some time to find b/c it isn't in the Vibrant forums at all.
I didn't say it didn't work. I don't have another company's sim to test it with, and *#7465625# doesn't bring up the menu, so I can't check it.

I must have missed that Disregard. Odd that the code won't bring up the menu, though. Do you still need to know if you are rooted though? If the Galaxy S Unlock worked (or even the fact that you could run it at all) then you are rooted. Did you grant it SU permission? If so, there is your answer.
Do you need anything else on this other than someone else's non-TMo sim card?

Go to network operators in settings. If AT&T is detected you should be unlocked.

Very strange. It shows that on the phone, but still doesn't get signal with her Sim card in. I'll research some more, and if any of you have theories, feel free to post them.

I didn't mean rooted xD sorry, I meant unlocked. It was 3AM and I still hadn't slept.
I have an idea. Maybe you need to set another set of APNs for ATT. Just a shot but Google ATTs apns and the go into settings>mobile network blah blah APN. Hit menu and add new, the put in what you Googled and don't forget to hit save. Back out and tick the ATT one and see if that works.
Worth a shot.
Thanks, I'll give that a try when I visit my friend again.
Thanks guys, it works now
Can you post your steps Please, I have the same situation and it does not work. I also have the Tmobile unlock code but their provided procedure was not work in ICS passion.
just fyi , I have the vibrant , no longer active on tmo , my worked changed to att , so i thought hell why not.
I rooted using superone click ,
I put the ATT sim card in ,
I dl'ed "Galaxy S Unlocker from market" by DaGentooBoy
I ran it and got error , dl'ed the "pro" version
I ran it and boom , worked like a charm , now phone works on ATT just fine.
I hope that helps someone
tried other methods first , but kept getting permission errors
While you had tried to find out , was simcard in your phone? so this one Galaxy S Unlocker from market worked for you?
thanks

[Q] Not Registered on Network

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

Atrix 4G unlocking SIM

I'm getting a bit frustrated... I have unlocked and rooted the phone and now I"m trying to unlock the SIM so that I can give it to my wife to use with a European Sim Card. I've googled, read and read and so far I've done the following:
1. Placed the European SIM into the phone (that I used in my old TMobile phone to date)
2. Was presented with "Enter sim network unlock pin"
3. Called AT&T and obtained the "unlock code".
I tried that code 3 times so far. After spending a fair amount of time with ATT support on the phone they believe that the "pin" is different from the "code". Btw, the unlock number was confirmed to me by ATT support folks twice... I rechecked the IMEI number twice... and I"m stuck... what do I do? Is there a difference?
Btw, I tried it under CM7 and AOKP
Thanks
SIM vs Carrier Unlock
There is definitely a difference between Carrier unlocking and SIM unlocking. I was steered wrong by AT&T the first time I asked. Essentially, they gave me a code that would allow me to override being locked out of my SIM card (to access phone numbers, etc) as a result of entering the SIM password wrong. This was NOT what I wanted.
I called back, and specifically requested a Carrier Unlock (for using other companies' SIMs), and they then made good on this request. You will need an active SIM from another carrier to get the job done, but if you specify your request to them, hopefully they will get it together. Another option is to buy a code at the numerous online re-sellers, but like I said, AT&T gave me mine for no cost. Good luck to you!

Thanks, unfortunately they keep sticking by their guns and claiming that the code they're providing me with is the proper one.....
Don't try too many times, after maybe 5, not sure, you can permanently lock your phone. It is a security measure.
You nay already know, but hate for you to mess up your phone.
I'm still convinced that there's no way AT&T or anyone else would be able to tell you remotely what the code is.
When you buy new SIMs, they come inside a credit card-shaped piece of plastic. On that card itself (not the sim), there's two spots: one for a PIN and one for a PUK. The PIN is needed because the new SIM defaults to being locked as a security feature. Every time you turn off the phone, the SIM locks itself. Once unlocked, however, you can go into a phone's SIM settings and leave it unlocked permanently for any phone.
You need to find the card that originally came with the SIM.
Chrism suggested not to attempt the wrong pin too many times. It won't lock your phone, it will lock the sim and then require you to enter the PUK code.
I still wonder if it is the phone. When you enter the code, then you can use any sim card. He wants to unlock the phone to work with a different carriers sim I believe.
His problem is with the phone, not with the sim, is it?
Could be wrong.

I believe this is correct. Also, if you are entering the carrier code, and enter it wrong a specified number of times,i'm pretty sure it can lock your phone. I have unlocked well over a dozen, and have always been warned about it....

Reread the OP. The phone is already unlocked and rooted. That means that technically yes, he can use any sim card on his phone.
However, not all sims are sold unlocked. As I mentioned before, it's not uncommon to buy a prepaid sim outside of the US (like the OP's Euro sim) and be asked to enter the sim pin upon start up.
If you reread the OP, you'll see that he's describing exactly what I'm talking about. I've had to do this a handful of times on a handful of unlocked phones.
Regarding locking the device, again, the OP phone is already unlocked so locking the actual phone due to entering the incorrect pin is impossible. It would be the sim that would be locked (since the phone is asking for the sim pin) and could only be restored by entering the PUK. I've had to do this a couple of times myself for people who had forgotten their sim pin but still had their original card info at home. Once you enter the PUK, it works again.
i would Spend the 20 or 30 buck online and get a diifferent code

Regarding post #8
I agree with post #9 as well.
Maybe so, not my experience though. He has unlocked the bootloader and rooted. He has not carrier unlocked. I don't think that they are the same, but you could very well be right. Thanks. At least we are all trying to help him out.
That sim seems to already be unlocked if he has been using it in a T-Mobile phone to date. His ATRIX is still network locked.
OP. Let us know please. Now I am curious.
Thanks.

I still haven't read where the OP stated he unlocked the bootloader. Rooted, yes. When I read "unlocked," I take that as "Carrier unlocked" the way that googling "unlocked cell phone" would bring up unrestricted/debranded/etc. cell phones, not necessarily having anything to do with the status of the bootloader.
That said, the bit about him using the sim on his older tmobile phone made me assume one of two things: he either forgot the code he used for that phone or it's a bad sim.
Granted, not every carrier unlock code works but given that he was getting it directly from AT&T (and it was on their servers), it should work. My Atrix, for example, required a code off Motorola's servers and even then the first code worked perfectly.
Trust me, if the OP has gone through all this trouble and the only thing left is to try the SIM pin then... 1+1=?
With the ATRIX you usually unlock the bootloader first, but that would explain some confusion.
Hey, I'm not trying to argue or anything.
OP, what unlock did you perform?
This thread is seriously non reality based.
Neither rooting nor unlocking has anything to do with getting the subsidy unlock code that allows non-ATT sims to be used.
ATT can cerrtainly provide the vaild code, and has always done so for me (albeit after possibly a await time).
3rd parties MIGHT be able to provide the same code. YMWV.
There have been some reports (search) that with the wrong radio the unlock code does not take. So ithat might be a way to go.
Wow, we are going round and round. Good luck.
Use search!!

Try THIS Thread---->Solved: Sim Unlock Fails With Valid Code
Sorry for taking so long to reply but for whatever reason I missed the email saying that there are replies. Anyways, lets recap
Phone is rooted and unlocked. I can run any ROM that I want and bootloader is unlocked.
The sim cards I am testing on (yes, plural) are not locked (as in they do not require a code).
I am trying to use a non ATT sim card (specifically I am trying TMobile EU) so that when I go traveling to EU again I can use the ATRIX with my local number that I keep rather then the ancient HTC windows phone that I have used to date....
I have made 4 attempts at unlocking so that means I am down to last one.....

[Q] use of a foreign sim

Ok so I (foolishly) bought a galaxy s4 with verizon even though I was moving overseas to Israel in two months. I made sure that the phone was world capable (like it can do cdma and gsm) and the guy at the store said it would handle foreign sims no problem. Once I arrived here I got a new sim. I figured out that it needed to be in gsm. From then on it had the service bar and confirmed it was connected to Orange. Since then I have been able to receive calls and texts, but not make them, every time I try to make a call before one ring I get a prerecorded message saying that my number cant be completed as dialed. I have tried several things already to fix this: to a cell phone repair person, to the local sim carrier where a lady tried using the sim of her own phone, customer service at verizon and samsung (who both told me to go see the other). I also did a factory reset which didnt do anything.
my phone is not rooted and is schi545 ME7. I will root if I have to, but if I dont I would prefer not to for the time being
Anyway I suspect the problem has something to do with the fact that I got the phone from verizon. Every time I start the phone I get the Verizon logo and after a minute I get a notification from the verizon set up wizard saying that I have a non verizon sim and that the sims source is unknown. I also tried disabling the verizon security and was able to make the notification go away but the problem persists.
Can someone with experience with this kind of stuff help me please? Thank you so very much:good:
Are you sim unlocked? I don't think the phone is unlocked. Talk to verizon to see if they'll unlock it.
According to verizon I am. I spoke with multiple representives from verizon and they said the phone was unlocked

Has any one told you if you have to change any apn, access point name? That may be the problem too. They can be specific to the carrier.
No, how do you configure that

In system settings, network & wireless, more, mobile networks, access point name. It'll be specific to the carrier so i can't help you there.
all LTE Verizon phones after Galaxy Note 2 are factory unlocked it must be a APN issue. Try maybe to do a factory reset and as previous poster suggested do the steps he told you to change the APN or look into I think it's called HiApn in Play Store.
Also try to put it in global mode or GSM? play with the settings.
still having problems
Thanks for all the input everyone but my problem still persists
I downloaded HiApn and followed its instructions to which told me to set up 3 Apns. I noticed that only one of them can be active at the time. I tried with each one active and I still can not make phone calls. Does anyone have any other ideas?

Go to Setting, call setting, disable the prefix international. I have done the same for using Verizon S4 in Indonesia.
Mine was not unlocked either, although I knew this before buying. This is a guide I tried (without success) to unlock it on my own.
Like the last poster, I reside in Indonesia, but I was never with Verizon. I rooted mine and have had no problems since.
Ok so I went to call settings and the closest I found was assisted dialing for international calls and the option to turn it on or off. I played with that for a bit and it didnt work.
I also tried the code and it said connection problem or invalid code
during my fiddling I came upon an app that showed promise of fixing my problem if I had adb shell. Does anyone have a good place to get that? I tried a few that didnt work out for me. There was another that showed promise but it wouldnt send a package no matter what I try
Thanks
If you want ADB, you need to download Android SDK and have Java Runtime Environment also installed. Then, it is just a matter of typing in "adb" into the command prompt of Windows.
Is there a serious conflict for you not rooting the device? The true benefit of doing this is to get SIM cards from anywhere to work, and to allow certain apps to work. Rooting is simply a matter of bypassing security parameters. As long as you follow instructions strictly, you won't have an issue using the phone as it should be used.
yea I suppose I could try to root it. Im just not great at that stuff and am worried about messing up my phone permanately

You don't need to root. You need to sim unlock. Get a hold of att international chat and adj them for an unlock code.
Hey guys thanks for all the help but I figured out that it was just a bad sim all along and that the first school screwed me over
But everything works now
