Can't I change the USIM during the contract period if I get a discount on the optional contract?

pu1. Yes, there will be an additional fee if you wear another USIM.

OK

pu2. Instead of receiving a 20% discount if you choose an optional contract discount,
There's a condition that you have to keep the same USIM on the same machine for the duration of the agreement
You can't put a U.S.S. on another device

OK

pu3. If you insert a USIM into another machine within the contract period, return the discounted amount
And even if I put a USIM in another phone, the contract will be terminated
There's also an extra charge

OK
