My friend asked me to download the micro will and make a phone call. Does this work?

Someone in the micro will use it. They can make calls for free with callback function, but they have to pay 15 yuan every month to ensure normal call quality and display the number. Under normal circumstances, the number cannot be displayed. If you want to use it, it depends on whether you want to spend money. If you want to spend nothing, you need to spend more traffic. If you use TouchPal mobile phone, the cost performance may be higher, mainly depending on whether you are pursuing free or quality.
