Hi this is my daughters phone,yesterday it kept saying no sim when she'd not even touched it and now it's asking for blackberry Id username and password, I didn't know password so I've reset it with the email sending me a link and now it's still not letting me in, I'm now on attempt 9/10 so if I get it wrong again were locked out!
Hopefully, this information will be of use to you.
Cheers, and Good Luck!
