Is there a way to reset my pin without Find my Phone, WiFi, location, and erased data?

[AC Question]

Hello. So, I've run into a dilemma with my samsung galaxy mega. I was trying the face recognition, and set a backup pin for when it didn't work. I tried using this pin, and it refused to work. I am 99% sure that it is the right pin, since I use it often. This wasn't a problem because my phone has almost always recognized me, and I just didn't use my pin. It is now problematic because when I restart my phone, it ONLY lets me use the pin. Yeah. I also can't use my Find My Phone to reset it because my location is off, and so is my wifi. So I am currently completely locked out of my phone, and I do not wish to erase my data. Help would be appreciated greatly.

Do you realise Samsung Find My Mobile uses mobile data?
