How much is the all inclusive basic fee upon cancellation?

Hello,

I am moving abroad on 30. November 2019. My mobile contract is due to expire on 27. March 2020. I have read all the forms (and numerous forums). I am trying to decide whether to submit for extraordinary cancellation because of moving abroad or to just submit a cancellation at the end of my contract period.

Everything keeps referencing an "all inclusive basic fee" but I cannot find any information about how much this fee is and whether it is higher than my regular monthly bill or not.

Given how close I will be to the end of my contract when I leave, what is the cheapest option? What fees would I be required to pay if I cancelled at the end of my contract period? How much is the "all inclusive basic fee" and what additional fees are added on early cancellation due to moving abroad?

Thank you in advance for your help.
