Wechat helps friends recharge their flow cards. Is it illegal, Zhihu?

It's not illegal. According to the inquiry of Amber Talk Law Network, the WeChat platform itself can charge phone bills, traffic cards and so on. It is a formal channel, so it is not illegal. There are two kinds of mobile cards. One is the same as a mobile phone card, with monthly rent and telephone charges, and you can make phone calls and send text messages. The second is the pure flow card mentioned on the Internet, which is the so-called IOT card.
