First try a simple reboot.
Second put off the Simcard and back if again > reboot then.
Third u can just have a look at google and search for the APN settings of ur provider.
Enter it and all should be ok again.
Much success.

I think you should contact your SIM card provider (telephone company) and ask for the unlock code (PUK) which is linked to your SIM card subscription and how to use the code to unlock.
Yes u need PUK code from sim card provider
Sent from my X10i using xda premium
I appreciate u all......
But its not about PUK code.....
Its that the phone isn't allowing any sim to connect to the network.....
the phone is blocked to the network......
Please cheak it out in X10 --> Settings --> Location & Security --> Set up SIM card lock --> Lock SIM card....
Its is in any x10 with any 2.3.3 rom.....
B careful..... dont block ur x10, like me..... :'(
I tryed other sims too.....
Plez help......

A SIM card is locked by 2 or 4 passwords
PIN1
PIN2
PUK1
PUK2
PIN1 and PIN2 are programmable by the end user the code is 4-8 digits long usually you have 3 attempts to get the code right, if you lock PIN1 or PIN2 out you then need the PUK1 or PUK2 which is the PIN UNLOCK KEY which is an 8 digit code provided by your Service Provider get this code wrong 10 times and its time to buy a new SIM card
Well this depends on what kind of "lock" you mean. A SIM card can be password protected (usually 3-6 characters long) by going into the Security Settings on your phone which is usually where you can chgange your phone's lock as well if it has one.....if you enable a SIM password this password is saved onto the SIM card itself which is a good security issue because if somebody steals your SIM card they can't just simply put it in a new phone and be ready to go....they'd have to know your SIM password in order to even get the phone to fully load up and connect to the network. Another thing that can be done is a SIM card can be locked due to someone putting in a wrong password too many times....if you ever get to this screen on a cell phone call customer care because if you try too many times you will fry your SIM card which would mean you have to shell out another $20 or so.....if that doesn't sound like what you meant than to my knowledge the answer is no but otherwise I hope this helps
So according to this......
the password is stuck in my x10....
which i cannot erase, or change......
coz my sim is working on other cells.......
so, wat should i do now...???
Plez Got no proper solution till now.....
M restless without my x10.....

[q] after updating to ics 4.0.3 rc4.2

plz help me ...after the update everything is working fine but i dnt get the service....i mean the mobile network is unavailable....i cant make any calls...:'(
Did you try to make a complete reboot of your phone?
First of all are you sure you didn't lock you Sim code ? (try to put you Sim Card in another mobile and check that you can make calls.
If you have done this, check if there is an option that turn this servise of.
ics
On the ics beta for the photon you can go to the dialer and type *#*#info#*#*
Click on phone info and scroll to preferred network. Make sure cdma (prl) or GSM is selected if not change. Also note whether it says the radio is on right below that setting.
You might also try to go to airplane mode and back, or wifi and back.
If all else fails return to your stock backup and make sure all is well.

After preparing sim it says with a "!" on the notification bar "cannot connect to desired network" .Then it means it recognises the sim.
When i prompt a network search it finds all the tree available BG networks and then "unable to connect to this network at the moment"
I just remembered now it didn't ask me to enter pin... so sim card not recognized. Back to FXP CM9

Thats why I asked you. Only solution is to disable pin code in other rom or phone. than it connects normally. You can still use patern as pin alternative, but it didnt secure your sim card if you lost phone or it will be stolen.

GT-I9300 unlocked, but not quite unlocked?

Yesterday I bought an S3 and rooted it straight away as I was trying to unlock it due to it being on EE. I couldn't do anything and downloaded Galaxsim unlock and paid for an unlock. Now everything shows as unlocked and so far I've tried orange and vodafone both work. I'm trying to get o2 to work with my S3 but it's not working and just says "Network is not registered". It also says invalid MMI when I tried something else I don't quite remember. Any help please?
This is in the UK by the way, I believe the phone is from germany though.
Did you check IMEI? *#06# Looks like you haven't got one....

I just checked and I do still have an IMEI.
Use this metod to Unlock it, works fine on JB 4.1.1 you can try even if you have 4.1.2 installed. Downgrade to 4.1.1 if you can't see option 4 from guide.

Type the code *#7465625# or *#SIMLOCK# on the keyboard of your phone. It’ll display various lock status information of your phone. This method should work on all other Samsung Android handsets.

Hello. I typed the code in you told me about, I had done it before it just says "connection problem or invalid MMI code" when I put an orange simcard in and "not registered to network" for o2. The thing UMTS method thing also wont work for me because as soon as I go on network lock it says "menu does not exist current command is 186." The apn settings are all correct.
I'm going to ask again, which version of JB are you using? 4.1.2?? If yes, you need to downgrade to 4.1.1 to use this trick

Sorry man I didn't see your comment at all, yes 4.1.2, so I can't continue to use 4.1.2 or do I downgrade, use the trick then upgrade?
Yep, downgrade to 4.1.1 first, use the Trick (missing option 4 now will be there), unlock & check if works. Once completed, upgrade back to 4.1.2. This method is permanent so in future you can flash any ROM and SimLock won't be back.

No problem final question, does the baseband number really matter too much? I've got an XXELL4 but I can't find one for 4.1.1. Sorry if that seems nooby it's just my first time downgrading
Here you go
Download any similar one, on the bottom of the page you can get 4.1.1
I might be wrong but I don't believe this method will work on non qualcomm devices.
Anyway, no "network unlock code" requested on boot means that your device is not sim locked anymore.
Did you check that your serial number and imei match those written on your box?

Nope. Just shows the same thing it did before "MENU NOT EXIST, current command is 186"
EDIT: If curiosity is killing you guys now, the phone couldn't get unlocked. Not even when I took it to the shop; every simcard worked except o2. They simply gave me another s3 and I was happy

Exactly same problem with JB 4.1.2
I fear if I downgrade I can lost the IMEI, happend some trouble with IMEI with the guy who try to unlock before phone comes to me.
The GalaxSim Unlock shows that the phone is unlock and all ok, but still recieve the "not registered in network" error message with any sim that´s not from the seller company
¿Any ideas for unlock in JB 4.1.2?
Thanks

There could be many different causes to this problem. Perhaps you could try factory resetting your device using the inbuilt recovery (if you are on stock 4.1.2). Does the same issue occur on a different phone (if possible)? Did you save any sms on your sim card? If you did, try deleting them using the stock messenging app.
Regards, gsstudios.
P.S: The thread title is not very specific. It's good to summarise the problem as best as you can so we can quickly understand your situation.
