1What's wrong with 9 yuan Flow Card?

1. The current is in vain. I spent 19 yuan to order 200G, which is almost useless, but the background shows that more than 60 g has been used, and it is estimated that 200G is equivalent to 10 g. 2. Advance payment. This kind of prepayment is generally paid through WeChat official account, and the extra fee is not paid to the operator, but to the agent. 3. The problem of imperfect after-sales service. At present, a large number of Tik Tok users have purchased this IOT card, and most of them said that they could not find after-sales service.
