Sometimes no SIM PIN needed

Since updating to 2.2, my Gen 1 iPhone has an intermittent problem. After it has been off for any length of time, the next powerup will sometimes (but not always) skip asking for the SIM PIN.
The passcode is working properly every time, but the next step, entering the SIM unlock PIN, is skipped once in a while, somewhat compromising the security of the phone. In other words, without entering the PIN, the phone is fully functional, able to call, access EDGE data, etc.
I have tried toggling the SIM PIN feature off/on and cold rebooting, but the intermittent problem always comes back, eventually.
Has anyone seen this or dealt with it?

Thanks. Here is how it is behaving:
• first thing in the morning, turn it on from a "cold" start: sometimes it asks for a SIM PIN; sometimes it doesn't.
• power it off during the day and power it back on again: sometimes it asks for a SIM PIN; sometimes it doesn't.
• do a full reboot (hold Home and Power until Apple logo appears): sometimes it asks for a SIM PIN; sometimes it doesn't.
Prior to firmware 2.2 it always asked for a SIM PIN under these circumstances.
• toggle Airplane mode off/on: does not ask for a SIM PIN (as long as one has already been entered).

HT204023 What is 'sim pin' under Cellular data on my iPad mini? How do I use that and change cards from one country to another?

I have a new ipad mini with retina display, and cellular capability.
I've learned how to set up an account and use it in the US. I'm now traveling internationally and need to learn about changing the sim card.
My first question is about the notation under 'settings', Cellular Data, SIM PIN. Under SIM PIN, there is an option of turning on 'sim pin' and then entering a PIN to lock the SIM.
What does SIM PIN mean in the first place?
Where does the PIN number come from?
Thankx.

A SIM PIN, also referred to sometimes as a PUK Code is like a PIN number for your SIM card (just like your ATM Card). Since your SIM card has your cellular account on it and can be typically removed from one device and put into another, you can lock the SIM Card with a SIM PIN if you choose. If you activate the SIM PIN feature and forget your SIM PIN when you try to re-activate your device or a new device in the future using the same SIM Card, you may have to contact you carrier to get a new SIM Card. http://support.apple.com/kb/ht1316
As far as changing the SIM Cards out because you want to use a new carrier, you can remove the SIM card fomr the old carrier and put in the SIM card form the new carrier. http://support.apple.com/kb/ht5163
I hope this helps clear things up.

HT201529 I bought my iPhone from Verizon and having their service. Does my iphone has a default SIM PIN?

I bought my iPhone from Verizon and having their service. Does my iphone has a default SIM PIN?

The 4G LTE SIM card in your device contains information about your plan, device and more. You can set a SIM PIN so others won’t be able to access that information if your SIM card is removed from your device.
If you remove your SIM card and insert it another device (e.g., when you upgrade to a new device), you’ll be asked for the SIM card PIN. You can find your SIM card PIN in My Verizon if you’ve forgotten it. Or, if you’ve entered your SIM card PIN unsuccessfully 3 times, you’ll need the PIN Unblocking Key (PUK) to unlock your SIM card again. After using the PUK, you’ll need to create a new PIN for your SIM card if you want to secure it again.
To locate the SIM PIN / PUK numbers for your 4G LTE SIM card:
Navigate to the Overview page in My Verizon.
Click My PIN and Unblocking Key (PUK) under About My Device.
Your default PIN and PUK will be displayed in a pop-up window.
Click Close when you’re finished to return to the My Verizon Overview page.
You’ve successfully located your SIM PIN and PUK.

How do I change my SIM pin?

I was robbed yesterday and my GalaxyIII was taken. Unfortunately I wasn't able to install any anti-theft apps, like Lookout. I already tried using Plan B, but the thief just uninstalled the app and turned the phone off. I don't want this person to remove my SIM card and insert their own, and be able to use a brand new phone that they didn't pay for! So I'm asking, how do I change or create my SIM PIN to keep my phone from being utilized by an unauthorized source? I'm very upset, I've only had the phone for 4 days. Someone please advice.

Hello amandasimms,
I am extremely happy that you're safe and I completely understand the importance of making sure your phone is not activated.
As ritsbits1212 and silver6056 stated changing your sim pin will not be effective in preventing another to use the sim card or phone and the best action to take would be to notify us right away.
We can suspend the sim card and services for you. We will also be able to add the phone to a negative list for you. This will ensure that no one is able to activate your Samsung Galaxy SIII on their account.
Please contact us right away and let us know if you need anything further.
Thank you,

IPhone 3G no longer asks for SIM pin since 2.2

Since I updated to 2.2 my iPhone no longer asks for my SIM pin after a restart.
If I reset the pin it works as it should for a while but if I reset the iPhone the problem reoccurs.
I did a restore but the problem persists. Any ideas?

I came on here because this morning I just noticed the same thing:
iPhone 3G 16GB
iPhone OS 2.2
I have the SIM preference set to a custom password (not the default) which should be requested on restart/reboot.
If I normally shut down the iPhone 3G (by holding the lock button and swipe) and restart, I have to enter the SIM unlock code.
However if I force a reboot (reset) by holding the home and lock buttons, upon startup, either immediately, or later, then the SIM opens unlocked, and no code is requested.
I also have an iPhone 1G 8GB with iPhone OS 2.2 and this does not happen on that phone. The SIM passcode is always requested and needed regardless of restart/reboot/reset method.

Default SIM PIN on iPhone???

Howdy all,
Does anyone know what the default SIM PIN is on the iPhone? In the SETTINGS menu under PHONE:SIM PIN, I am trying to turn the SIM PIN on, yet it keeps asking me for a password. It says I have 1 attempt left, so I don't want to enter a code until I am sure I have the right one. I've tried calling Apple and they transfer me to AT&T... and then AT&T transfers me back to Apple... and repeat.
Any suggestions would be greatly appreciated.
Thanks All.

Any Device specific information can only be provided
by APPLE CARE 1-800- MY IPHONE. AT&T only
troubleshoots network issues and checking to make
sure your Visual Voicemail is setup correctly in
their systems. Basically if you wanna know how to use
youriPhone, call APPLE!
True, but the SIM is an AT&T controlled component, not Apple. If you call AT&T CS about the default PIN, they currently don't know since it's not in the Apple manual. I even raised this up to a director level there. If you call Apple, they tell you call AT&T. No one wants this hot potato...
The default PIN needs to be put into the User Manual. It's inexcusable to leave it out since inserting the wrong PIN 3 times results in the SIM being blocked and a non-functioning phone until the PUK has been entered or the SIM replaced by AT&T.

SIM PIN

I have just upgraded from a 3g to iphone 4. I restored the 4 from my latest 3g backup but the phone no longer asks me for the SIM PIN on startup. When I switch SIM PIN on it doesn't recognise the old number.
I have one try left. Is there a default PIN for the iphone 4?

Can I ask a question. If SIM PIN is enabled, do you need to enter the PIN every time a call is made or just when the SIM is inserted into a new phone?

Where do I find my SIM PIN and PUK code

Plz help

Contact your carrier. If you don't know the sim pin, you'll need the PUK code, which you get from your carrier.

My phone is locked and i can't unlock it without a SIM PIN

some how i locked myself out of using my phone and i need a SIM PIN to unlock it, but i don't have it

Not clear just wht you have done...do you have a passcode set and did you misentering the passcode? If so you need to restore using the recovery mode described in http://support.apple.com/kb/HT1212

No data on the iPhone should be erased or touched when activating a new SIM card via the iTunes sync process.
Contact info on the iPhone is designed to be synced with a supported application on your computer. The same for calendar events and bookmarks.
All iTunes content and photos transferred to an iPhone should remain on the computer the iPhone is synced with for this data.
Photos available in the iPhone's camera roll should be imported by your computer as with any other digital camera.
So to be on the safe side beforehand, import all photos available in the iPhone's camera roll, and sync contact info, calendar events, and bookmarks with the supported application on your computer. Sync with iTunes immediately beforehand to update the iPhone's backup if needed. The iPhone's backup includes data such as most iPhone settings, email account settings, contact info (but you shouldn't depend on this one alone), SMS messages, notes, recent calls, call favorites, 3rd party app data and any data created and stored by a 3rd party app, and photos available in the iPhone's camera roll - you shouldn't depend on this one alone either.

How do I change my iPad mini's SIM PIN when I cannot remember what the original PIN was?

I went to enter a new PIN so I could lock my iPad's SIM card and was asked to enter a number. At some point, I must have entered a number already, because I got a message that I had entered the wrong one. I can't seem to choose the "change PIN" option, probably because I can't recall the original one. How to I change the SIM PIN? What happens if I use up all my chances at entering the PIN and don't hit on the correct one?

Thank you for the reply.
I have one chance left to enter a number and then I will be locked out of
4G service. So, I have not tried 1111. What will that number do?
When I log into MyVerizon, it does not offer "view all" as an option under
My Device. Instead, under My Device it only offers the following:
My Device
Apple
iPad mini with Retina display 32GB Space Gray
Other Options:
Accessories

My Plan
300MB for $5 Daily Plan
View Plan Details
Other Options:

There is no place I can find that provides with a PIN or PUK. I have tried
clicking on all the options listed above.

Lumia 720 powers off, requires SIM pin after Amber

Hi. I notice that my 720 would randomly power off after the Amber update. It would happen when phone is not in use, I would turn it on but would have to enter the SIM pin for it to function. 3rd time its happened today, within 6 hours.

hi mate
have you checked that you are up to date with all the latest Nokia system app updates? also try performing a soft reset to see if that helps.
