Yes, by default it is 1111. However, it is possible to lock your Big Red Roaming SIM by entering the wrong PIN number 3 times or more. If this occurs, please contact Big Red Roaming Customer Support to retrieve a PIN and PUK code for your Big Red Roaming SIM. Your PIN number, as well as the PUK number (PUK stands for Personal Unblocking Key), is printed on the credit card sized piece of plastic you received your Big Red Roaming SIM card in.
