Was your old sim card on a different network from where you got this phone from? If so speak to your carrier
This is the code you need to input when you stick a sim in a new phone. Some sims have this code some dont. You can add one or change the code as you wish. The existing code will either be something you set, or something the operator set on the sim. Have a loom at the operator docs. Sometimes these are defaulted to 1234 or 0000. Dont enter it wrong too many times or you'll lock the sim. You need the PUK code to unlock a sim for which the wrong sim pin has been entered too many times.
Other poss is that the Z1 is not sim free and is thus asking for an unlock code to allow you to use s sim from another network. There's a thread on here somewhere regarding what to type into the dialer to get to the service menu. The service menu will tell you whats locked.

no sir, it's the same network
Then go to your network provider and ask for another sim card, it should be free

Hi there,
First of all congratulations on the forum. Very good stuff here.
I have a problem in a new Optimus Black. It says "Sim Network Block".
What it means?
Thanks in advance.
Greetings to all.

1. Perhaps it's related to your GSM SIM card? What if your SIM inserted to another phone, is it the SIM card fine?
2. Do you have any other SIM card to be inserted to your OB phone? It still had error?
3. Where did you come from (country)?
4. Your ROM version (10A, 10B, 11A, or else?)
Sorry to answer with question, but AFAIK this case is "new" with LG Optimus Black, and you didn't mention such as those information..
Thanks.
Sound to me like a SIM lock, or to be more specific: like a network lock.
Some service providers "lock" the phones they sell to a specific SIM (SIM lock) or at least any SIM of this service provider/network (network lock). I don't know about other countries, but in Germany this is mostly used for cell phones that are sold as pay-as-you-go/pre-paid offers while "regular"/post-paid contracts mostly have phones without any lock.
Most times such locks can be removed by yourself, but it might be illegal in your country (depends on the country). Otherwise you could contact you service provider and ask for an unlock key - but you will probably have to be a huge "fee" for that...
And before you ask: nope, I have no clue how to remove the lock. ;-)
It's SIMlock. Go for eBay and by unlock code for ~3$. It's really cheap.
It's seems to be a SimLock. I've tried 3 different sim cards from different networks, it happens in all of them.
The codes in Ebay are secure? It seems so cheap.
Thank you all for the answers.

Yes, no probs with them. Buyed one and it worked.
I'm trying to unlock the Exhibit 4G this week for use on a trip abroad (and yes, it is legal to do so since this was a prepaid phone paid in full in 2012 so T-Mobile did email me the unlock code - all that is good). What I don't understand is why it is not prompting for the Unlock code at boot. T-Mobile says I must have another company's SIM card in the phone to unlock the Phone. So, I bought a Simple Mobile SIM and placed it in the phone but it just boots up to the ROM as normal without asking for the unlock code. I am using the Linaro 4.2 rom (which is amazing btw!) but I also tried with Peach Sunrise 3.0 and Cyanogen 10 - nothing but a normal boot with no phone capabilities. So I have these questions: Do I actually need to pay for SimpleMobile service first to get the phone to recognize the SIM as different and ask to unlock? (seems unlikely) - Is Simple Mobile just not a good SIM to use for unlocking this phone... Or do I have to go back to stock ROM and unroot to unlock this? Of course if there are any other apps or shortcuts that will let me get straight to the unlock code prompt I'm all for it. Any help is greatly appreciated - not finding a lot of answers out there on the net and if it is on this forum I apologize for not finding it and would appreciate a link to it - Thx!
You probably need a different sim card. As I understand it, T-Mobile phones don't need to be unlocked to work on Simple Mobile.

Thx - it figures I would choose that one to buy!
Meekrawb is right, simple mobile uses the T-Mobile network.

To get your IMEI go to your cell phone and enter *#06# This will give you a string of numbers you will need to unlock your cell phone. Enter *#06# as if you are going to make a call. Then you will be given the string of numbers you will need.

After you obtain your IMEI and copy it on a piece of paper, power your cell phone off. Take the back off if you have a removable back. Take the SIM card out. Put a BLANK SIM card in its place. Power the cell phone on. A screen should come up asking for your IMEI number to be entered. It should look like a rectangular box. Enter you IMEI. There should be a small box under the rectanglar box that you press. The phone should then eventally unlock itself. You can test it by putting a different SIM card in your cell phone.

Hey guys, currently in Italy and tried to SIM unlock my phone using the instructions in BadBoyz Rom so I can use a Wind SIM, but my phone keeps asking for a pin then a puk code. Please help.
I think this is a code which was provided to you by your Service provider. If you enter puk code incorrectly 3-5 times your SIM will get blocked. Call your service provider and ask them what is the number or look for the original papers included with the SIM card and you will find the numbers.

I have one sim that I wish to use for phones / text messages, and one that I wish to use for mobile data.
If I put either sim in on its own, it works fine.
If I put both in together, and set them so they are both on, the one that I wish to use for phone calls and texts does not register on its network (which is Three in the UK)
I am not sure what to do. Can the phone company have set it so it doesn't work in a dual sim setting?
Or have I just failed to understand what dual sim is?
Any help much appreciated!

Try interchanging the SIM, I mean just enter the right one on the left and the left one on the right. What you are saying shouldn't happen.
If possible try another 2 SIM to see if the problem is with the SIM or the phone.

OK thanks. I have tried it with another 2 sims and it works fine. So that means it's a faulty sim?
Is it possible the network won't allow dual sim, or should I just request a replacement?
Thanks

Before requesting a replacement just ask the network operator of that particular SIM that if they disallow Dual-SIM or not. If they don't allow using their SIM on a dula-sim mobile asking for a replacement would be pointless.
I am using 3 (UK) and Vodafone, no issues, so likely the sim

Hello,
I bought a new sim card with a new plan. it came with enabled 0000 pin code.
The problem is my P10 is not showing the message at start-up asking me for the pin code.. and i couldn't get network. I'm stuck at ''emergency calls only''.
Anyone has an idea about this problem ?
PS: i don't have any other devises on which i can delete the pin code.

I tried and it does not work.. it's like the device is not reading the SIM at all. when i try to set a sim lock (i know from my operator that it's already locked on 0000) it just said wrong code, remaining attempts: 3.

(If you have Dual SIM model) have you tried in both slots
Also, are you sure that the phone is unlocked for that operator
I doubt, if you would even remove lock for that SIM on another phone, that P10 would still show Emergency calls only

Yes, it's a dual sim model, i did try in both slots.. same result for the new sim with the preset PIN.. but i can set a code for the second sim (does not have a pin code).
The phone is unlocked for all operators.. it's just that it does not ask for pin code at start-up.. and acts like it didn't read pin locked sim cards at all.. it's not the first time i find myself searching for another device to delete the pin code.
