no, the mobile phone 3 years ago was not a smart phone. It can't access the internet. Pinduoduo is an online sales platform. And it seems that there was no mobile phone 3 years ago. Even mobile phones appeared in the late 198s and early 199s. At that time, landlines were not common. Take mobile phone, for example. How can it get online? I suggest you buy a new mobile phone. And I don't need any brands. As long as it is a smart phone. Can install Pinduoduo and other network platforms. You can realize online shopping.
