I'm not sure. I think it's a bit like pyramid selling. It's really boring, but there's nothing wrong with using his phone It's best not to believe those things. The dial card is not very good, and the calling software is too expensive. Not worth it. It's best not to believe it casually. Do something else. I can't believe it. I told my fellow villagers to add it, but, in a word, miserable! You can also make a phone call. The phone bill is relatively cheap. Can be used as a user. Don't register as a member. I don't think so.
