@NapcorsecondMost likely you will need a new SIM. PUK etc are store on the provider side. But it really depends on how you define "hard lock"
What i meant to clarify, is in the event the phone is SIM locked you only have a limited number of attempts to enter the proper code untill the phone will no longer allow you to at all, then the lock is permanent.
After chatting with Rogers, swapping Sim cards and 2 separate chats with Samsung, everything now works. I had to input not 1 but 2 separate PUKs supplied by Samsung in succession. Thanks for everyone's input.
Ihave attemted to unlock too many time no what can i do
If you have attempted to carrier unlock your phone multiple times, it may be now permanently locked to that carrier. Some phones have a unlocking reset code that can be entered so that the carrier unlock code will work again. The manufactuer should be able to provide that.
Hi. I just had this issue with my Samsung S7. I obtained the PUK from public as well as the PUK from Bell my old provider but neither worked. Then I found the below post and it fixed everything.
If you need to unlock your Samsung phone, here's how. You will need the following codes:
1) The Master Code Key (MCK), also known as a DEFREEZE or UNFREEZE CODE and/or;
2) A Network Control Key (NCK) also known as an Network Unlocking Code (NUC). This is the main network unlocking code.
Both of these codes can be obtained directly from Samsung via their live chat feature in a matter of minutes. Don't waste time trying to get them from your old/new service providers.
It's important to note that what Samsung handsets refer to as a "SIM Network PUK" is actually the Master Code Key (MCK). It's exactly the same thing and it seems a poor choice of terminology by Samsung has caused a lot of confusion and wasted time for numerous people.
Instructions for unlocking.
1. Power off your device and insert the SIM from your new service provider.
2. Power on. If your device gives the following message you need to enter the MCK. "SIM network PIN blocked. Enter SIM network PUK." (See step 4 if your phone asks you for a SIM Network unlock PIN).
3. Enter MCK. It will likely tell you the code was "unsuccessful" however disregard this.
4. You should now be at a new screen which asks for the "SIM Network Unlock PIN." Enter the NCK here. Note you only get one chance to enter the NCK, so do NOT make a mistake.
5. You should see a message saying "Network unlock successful." Your phone is now unlocked.
I hope this helps.
@cellphoneuser1 I'm not sure everyone in this situation is guessing codes I think initially they assume they know and the phone has it wrong. Three attempts isn't much before its locked. Once... Twice because you could have screwed up... I constantly switch my 9's with R's haha... Glad it's been solved though as I didn't see that part before commenting.
