possible to freeze my account for 6 months?

Hi
I'm in to few months of my 2 year contract, but I just sold my house and I don't move into my new house for another 6 months.

I'm going to live temperately with family and they already have internet.

Is it possible to put my account on "hold" mode, not pay any monthly charges, until I move into new home?

I don't want to cancel.

Thank you.
