Seeing your out of contract ...
You can do whatever you decide ...
I think I may go the option you mentioned, Cancel and reopen when you get moved into your new place, this way you may get the New sub promos, maybe ... you would also get new equipment if your needing new stuff.
Don't know what your currently using ..
Another thing to think about ... If you Cancel and re open, you will then be in 24 month commitment.
If you simply suspend your account, you won't be in a commitment when you turn it back on.
