How do I calculate the penalty if I buy a cell phone with an optional agreement and cancel it after using it for about 3 months?

There is no official subsidy, so is there any penalty?

The entire discounted amount for 3 months under the optional agreement is a penalty.

As you know, there is no significant penalty because there is no public subsidy.
There must have been a discount on the optional agreement for three months.
You can pay that amount again.
