What is the use of the mobile QR code scanning version of Shuangshoubao?

Shoubao has the calling function of an ordinary mobile phone, but the biggest difference between it and ordinary mobile phones is that it has no on-screen keyboard, cannot access the Internet, and cannot send text messages. Four numbers are preset, six and seven. Children as young as 20 can quickly master it, which can solve children's daily communication problems and effectively prevent the impact of bad phone usage habits on children's study and life. Moreover, Shoubao adopts Tianyi CDMA technology and has ultra-low radiation, so parents can safely let their children use it. At present, China Telecom has launched a "June 1" gift package. For only 600 yuan, you can get a Shoubao terminal and one year's service usage fee (the service usage fee is 20 yuan per month, including 100 SMS positioning and power on/off per month) SMS notification, 300 website positioning functions per month, black and white list filtering and management functions. Local calls are free, local calls are 0.1 yuan/minute) and 10 yuan of free phone calls per month for 24 months. If you are a "My e-Home" user and handle the Shoubao business, you can get a 220 yuan Shoubao purchase subsidy.
