Sim card was blocked

[Avgona]

Hi ! I've bought Videotron in Montreal in June 1, then moved to Toronto.

Today my and my girlfriend's aim card were locked. What's the problem and reason?

How can we unlock them

If you entered 3 incorrect PIN codes and your phone displays “SIM card blocked” or “Enter PUK code”, your SIM card has been blocked to ensure your security. To unblock your SIM card, you must enter a PUK (PIN Unlock Key) code.

To unlock your SIM Card, reset the PIN by entering your SIM Card's unique PUK (PIN Unlock Key). Note: Entering an incorrect PUK (PIN Unlock Key) 10 times will permanently lock your SIM Card. If the SIM Card becomes permanently locked, you will need to swap it for a new SIM Card.

@Cynthia5464  No, I've been using Videotron since June 1, but it was suddenly locked. Can you verify in database what's the problem has occurred

I haven't entered PIN or PUN actually since June 1, so that's not that case
