Zhaoqing wants to buy a Samsung i9300 Unicom version. How much does it cost?

From 3,500 yuan to 4,000 yuan, you can go to Unicom's online business hall www.100/kloc-0.com, click "3G mobile phone" on the home page, and select the mobile phone brand "Samsung" you need to know, and you can get the corresponding information. If you have any questions, you can contact the homepage "Online Shopping Guide" for consultation.

I saw that there were two activities, "prepaid phone bill to mobile phone" and "purchase phone bill to mobile phone", both of which were within 4000 yuan.
