SIM network unlock PIN - Galaxy S II Q&A, Help & Troubleshooting

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.

[Q] Samsung Galaxy S2 - Cannot make calls

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

[Q] Samsung Galaxy S3 was unlocked, now its locked again...

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
Sent from my GT-I9300 using xda app-developers app

[Q] Simple unlock issue?

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.

Samsung Galaxy S2 network sim lock

Hey guys. I have looked into almost every topic on this website that I could find about unlocking the phone. Tried most apps. But not successful! Even when I enter
Code:
*#7465625#
nothing appears! I strongly believe that the network has been frozen. I could not find somewhere to tell me if I have reached the number of allowed tries nor how to crack a network freeze!
Any help or threads I have no found (been searching for the past 4 hours) will be very much appreciated!

Is there a way to remove locked networks on a rooted S8

Hey all,
I'm hoping someone can shed some light on an issue I'm having. I've googled my life away and all i get is the same videos of tutorials telling you to go to their website and pay $30 or £25 etc.
When i put another sim card into my phone it comes up with
"Sim network locked. Please enter sim network PUK"
I enter the PUK for the sim card but it says "network unlock unsuccessful"
I have acquired the unlock code for my samsung S8 edge from my provider but nothing i do seems to work. Tried loads of sims, loads of PUKs but to no avail.
Ive rooted my phone and was wondering if there is any other way by tweaking the settings somewhere that will open it up to other networks has i f***ing hate Vodafone
Thanks for any help in advance, i'm going out my mind with it
Thanks
Chop
