How to reset an iPad if I don't have access to my old phone?

This is actually a question for a friend. I little back story.

She bought an iPad here in US & then took it to Sweden. She registered it with her then Swedish cell phone. About a few months ago she came back to US and tried to access her iPad. Evidently because of the country change the iPad then needed her to enter a PIN that it wanted to text to her Swedish phone. Unfortunately she gave up that cell service/phone number when she left Sweden (or in other words, she doesn't have access to her old Swedish number that the text with the security code was sent to.) She says that she tried to guess the code but now the iPad had completely locked up on her.

Is there any way she can get into the iPad now?
