Yes, everything stays the same, just that you dont have a binding anymore

Just dont do any alteration to the contract like, take out a phone number, or change equipments.

any change u make to the contract will renew it for another 24 months.

With that in mind, whenever u want to cancel after november, u junt need to deliver the cancelation form in any NOS Store. 

Um bem haja

Regards

William Keith Goodfellow
