I'd like to hollow out the Mate 20 Pro with a new contract at O2, to be exact this offer here (link). I have compared some offers and it is always of a connection fee of 39.99 euro the talk, why should always cost 40 euro to "join" me… Well, I know now but not how much I then have to pay in the end because that is never properly listed, so the total price.
Is it 1: device price + connection fee + first monthly rate = ~ 180 euro
or 2: device price + connection fee = ~ 140 euro

Why should not a first monthly installment be due in the first month?

You pay 180 euro and then 40 euro / month.

Aha, thanks for the answer. Sorry for my ignorance… I also did "research", just never got an exact answer.

These are 24 x 39.99 euro + 99 euro for the device + 39.99 euro connection fee = 1098.75 euro

Cell phone itself is available from 850 euro.
