Are you saying you haven't chosen a new plan but want to take it offline? If you have chosen a plan, you can always take a network offline/online. That's entirely up to you and changeable.
If you haven't chosen a plan and you take your network offline and later want to check and see if it is still able to be rescued, you'll need to let us know via the Help Center so we can check manually. If we can get you set up, we will, but obviously it won't be around for much longer. Hope this helps in some way.
