It's a huge difference. It's hit or miss with the individual plans. NW 450 is an individual plan. NW 700 is a FS plan.The only difference with this account that I am trying to purchase this on is that the NW 700 minutes was changed to NW450. Not sure if that would make a difference or not. If it does then I guess I'll have to change it back somehow to the NW700. That's just my theory :/
Do you have UL text with the 450 minutes you are trying to add a new UDP line too?
