What are the conditions for canceling the mobile phone service?

cell-phone smartphone mobile cellphone withdrawal-of-operations

As far as I know, within a week after the cell phone is opened, it will be withdrawn.

Even if you buy a normal product, you can't return it if you open it or just change your mind.

Even if I opened the product and used it for a while, does it just accept the cancellation of opening and the return of the product within a week?

Or is there any other condition?

You can apply for withdrawal without any conditions within 7 days after the mobile phone is opened.
All you have to do is return everything you received at the time of purchase and pay the fee you spent for a few days.
There's no penalty.
