Hello! First time poster here. I'll start with a quick overview:
My mum had a galaxy s2 on an orange contract. She's decided to give it to me. However, when I put my tesco mobile SIM in the phone and try to call it says 'Mobile network not available'. I tried to see if it needs unlocking by dialling #SIMLOCK# but I got the same message.
How do I fix this problem? Is this a case of me needing to unlock the phone? My mum has never gone on the internet with the phone and so won't have installed any new firmware etc.
Sorry if this comes across as a simple question. Any help appreciated!
Yeah it is simple.
Root phone,backup efs then use helroz unlock tool.

Hi People
I recently bought a second hand Samsung Galaxy S2 locked to T-Mobile (UK).
I unlocked it (Chainfire Galaxy S2 Sim unlock utility did not work) using Helroz unlock utility. Installed O2 Sim, phone booted fine. However I cannot make calls with any SIM inserted into the phone.
After much research and many forums later I put android 2.3.3 on the phone - mainly because I only had a single CSC Code (TMU - T-Mobile UK ?), installing Andriod 2.3.3 allowed me to choose a generic CSC Code XEU (*#272*<EMEI>#). This did not help still cannot make calls.
I decided to install Android 2.3.4 samfirmware - still cannot make calls.
I bought a T-Mobile Sim and inserted into the phone the name of the network (T-Mobile) is now shown (previously it said "Emergency Calls Only") but still cannot make calls. I have spoken to T-Mobile and they have assured me that this phone is not barred from their network.
Currently have Android 2.3.5 installed (samfirmware) - still cannot make calls and cannot send texts either.
Any help would be much appreciated - but please speak slow as I am a noob!
I apologise if this issue has been dealt with in another thread.
The plot thickens
I spent some time on the phone with T-Mobile yesterday and this morning my phone CAN make T-Mobile calls.
If I put *#simlock# into the dialler it tells me that the
Network Lock [OFF]
Network Subset Lock [OFF]
SP Lock [OFF]
CP Lock [OFF]
Therefore I assume I should be able to use this phone with other networks, but I cannot use it with Vodaphone or O2.
The CSC code is XEU (*#272*<EMEI>#)
Any help much appreciated.
Help needed
Any help with the above problem would be very much appreciated
having the same issue here tried *#simlock# and everything appeard just like you mentioned did you find a fix for this Im trying to get my gfs phone to connect to giffgaff
Dont like the sound of that. Am seriously looking at getting an S2 on a 24 month contract this week. I dont normally bother with contracts and usually buy factory unlocked, but on seeming to read these were pretty easy to unlock, I figured I had nothing to lose.
Now not so sure. Have you managed to solve this?

My GF bought this through ebay and its looking like its been barred from what the replys on giffgaff are suggesting, plus from googling Id say me and the OP have been the only people that have had this issue so far...The SG2 has been exceptionally reliable so far for myself plus do some shopping around and get a 12 or 18 month contract as 24 months are just overkill
Hi All,
I installed JB 3.05 AOKP a few days ago.(I have SGS2)
a few hours ago, came from nowhere, I lost my network signal and Cellphone keep asking for "SIM network unlock PIN".
I talked to my operator and the couldn't find a way to help me.
I've tried to install Galaxy s2 unlock sim app from Play and i allowed it to get to Root, but it couldn't find any pin code...
to be honest I'm kind of desperate..I sold my iphone 4 just because I had the feeling things like this will never happen to me in Galaxy and android system...(and because I don't like apple,but this for other discussion).
Please,you are the experts...Please Please tell me that my cellphone is not just a brick...
Thanks in advance for your time.

Hello,
I have a UK version of the S3 (i think its the I9300) About a month ago I had it unlocked from the 3 network (UK) by one of the hundreds of shops that offer unlocking services.
When the phone was unlocked I could enter *#7465625# and it would say that the phone was unlocked to all networks ( I don't remember the exact words) Anyway all was good until last night when my phone upgraded something (I got a reminder in the notification bar that there was an upgrade available) - I've done this before. Now it is saying that the phone is SIM network locked again. And I am unable to enter the code to see whats up.
When I got it unlocked, I was told (obviously incorrectly) that once the code has been entered the phone can never lock itself to a network.
It seems to me, that somewhere in the upgrade 'Three' (who the phone was locked too) has made the phone relock itself.... Has anyone else had this problem, or can point me to the right forum. FYI I am on the O2 network.
Thanks in advance.
Seems like a bit of a nuisance, if every time the phone upgrades it relocks... Perhaps I need to Root the phone..
Known issue on some phone with the latest ICS updates from samsung
Use GalaxSim Unlock to re-unlock your phone
(needs to be rooted)
Update make your phone lock it self common thing.Mate this shops ripe u off. Just root your phone and take simlock using one of the apps from market or voodoo unlock. There is pleanty tutorials how to do it on xda. Its not really complicated o and u can try galaxy S 3 toolkit I think u can take simlock as well using that program hope t helped

Hi, I am looking for some help/advice about a Samsung Galaxy s2 (GT-i9100).
I purchased this phone new and unlocked in the UK back in October 2011 and have been using it fine over the last few months. Recently I gave this phone to a friend who was going traveling in India.
She bought an AirTel sim and used it in the phone for the past several weeks, however, last week she woke up and the phone was asking her to enter a “Network Access Lock Control Key”, and she can no longer use the phone or data (wifi still works).
I’ve done some research and it appears that the phone has somehow locked itself to a network. So I am now trying to figure out how to help her restore connectivity.
I know you can buy unlock codes online, however, we don’t know what provider the phone has locked itself to and all the unlock websites I’ve been on need you to specify the network provider. Is there any way of finding this out?
I also know you can get apps from the app store to unlock, however, you need to be rooted to do this, and this isn’t an option due to where she is at the moment.
So, does anyone have any advice or suggestions?
She has been to AirTel and they don’t know what is going on, she also took it to an official Samsung store who did a full firmware re-install but the phone still appears to be locked. Would this code be available from Samsung?
Any advice or suggestions is appreciated.
Thanks.

Tell ur friend to do the below and see if it resolves the issue
1)Turn off the phone and then remove 'Simcard'
2)Turn ON the phone without 'Simcard' and let it boot completely.
3)Turn Off the phone again and this time put the 'simcard' back.
4)Turn ON the phone with 'Simcard' and let her have 'Finger's Crossed' and pray god not to give the same issue until she leaves INDIA

I think you need to be rooted: he says thats not an option.
Sorted out now
Thanks for the suggestions but we managed to sort it out now.
After much research we rooted the phone using cwm-touch (ver 6.0.1.2-i9100) and the SU-Busybox installer zip.
We then used the GalaxySim unlock app from the app store to unlock the phone, all seems to be working now!
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.
Did you try spockys app

If you dont know what it is; then one would presume you havent tried it.
You can do a google or xda search, or charge up the iphone.........

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.
