Hello I'm new to these forums and I've already run into a problem. I recently changed my contacts memory from phone ---> sim. As I was trying to change it back, it asked for my security code. Me not knowing it I willingly tried the default number I found on many sites, 12345, to no avail. I was wondering if there is any other number I could use? My IMEI is: 357065002481309 Thank you in advance.
