The monthly refund of 245 is based on your total telephone bill of 5888 minutes for 24 months, but IPHONE4 requires that the guaranteed package must be 286, so you have to pay 4 1. 1000 every month, which is caused by the number you choose, and it should be an AABB type number. I opened the card myself, so I prepaid 300 phone bills, because I handled the package of 286. This is to prevent you from stopping the phone as soon as you start it, because the refunded phone bill will take effect next month. Another fee is your number selection fee. But this 1000 arrived in time, don't worry. So you don't have to pay in the business hall for a long time.

I hope you are satisfied. Unicom employees answered.
