When I try to USB-tether, my 9800 tries to dial/call "#777" ?!

Hey guys,

Whenever I'm trying to connect to usb-tether, my 9800 attempts to dial "#777"...

Would anyone know why this is happening?
I was tethering fine for the last month or so, it just started happening today! So confused!

#777 sounds very familiar.. Like it has to do with a connection or something, but I can't remember exactly. I'm really thinking hard trying to remember because now it's going to keep bugging me that I can't remember what it is. If I do remember it, I will edit this post.

#777 is the number I dial for my carrier but they are all different. Are you using DM to tether? Have you went into the options and chose your carrier?
