Can this be disabled?
Kids could easily do this by accident or even someone having a laugh.

The PIN code is on the SIM card, not the phone (you may already know that) - the phone itself doesn't know your pin. The phone sends the PIN entry to the SIM card and the SIM card will either say "Accepted" and unlock, or it will fail and remain locked.
After 10 (usually) failed attempts, the SIM will lock itself. You can Unlock it by using the PIN Unlock Code (PUK). This is NOT the PIN code, it's called a PUK code. You may be able to obtain this code from your carrier / operator.

I was on Sprint recently, and upon entering my account I saw this option "Get my PIN1/PUK1 unlock code". What exactly is this and where would I use this at on the phone. Also are there and advantages or disadvantages to no having my PIN1/PUK1 unlocked.

it's if you happen to lock your sim card on accident you would need the PUK code to unlock the sim in order to be used again. I work for AT&T and I get this call on a regular basis.

Since I would apparently want to avoid doing this, how would one lock the SIM card inadvertently? I'm going overseas soon, and wouldn't want to mess up my foreign SIM card. :fingers-crossed:

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

I purchased a used Incredible S and when I purchased an unlock code online I was able to network unlock the phone. 2 days later it failed to read my simcard anymore, did it lock back up? It doesn't give me the option to enter an unlock pin like the first time I unlocked it, so how can I check if the phone is still unlocked? or how can I input my unlock code again if it needs it again? HELP
Also, the sim card still works fine in my old phone so it isnt the sim.
So phone won't send text messages suddenly and having found some advice the fixed dialing is on. But to turn this off I need the pin2, but I've no idea what this is or where to find it!
Can anyone help?
Mine wouldn't send texts after a recent update. I force closed the messaging app in settings and it worked fine after that
Pin 2 is usually on the SIM card, so you'll need to ask your provider what the code is

No, pin 2 is the PUK code and that code should be on the plastic card that holds the simcard incase you fail the pin1 3 times.

Actually its not. You have 2 PIN's on a SIM usually, and PIN2 doesn't get printed on any of the supplied details with the SIM.
For each PIN, there is a corresponding PUK and PUK2.
And then you discover it's a network problem!
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.
