How long is the contract period if I sign up by moving my cell phone number?

pu1. If it's a public announcement, use 69 kt for sk and 59 kt for lg for 6 months
After six months, you can switch to a low-cost plan
If you make a previous engagement, it'll be reduced to four months

OK

pu2. It's based on the short-term communication law, but the plan is 6 months, and the cell phone installment plan is 2 years
