After the mobile phone has no traffic and no monthly SMS, which is more cost-effective to use QQ or SMS?

If you chat continuously and use QQ on your mobile phone, you shouldn't spend 1 yuan an hour. I can't say a few words. It's more appropriate to use text messages. What's said upstairs is also reasonable. Use Fetion, but add friends first. Your friends may not be able to pay attention to your news in time. It's better to use mobile QQ. However, there is no cost-effective traffic package of 5 yuan. Chatting casually on QQ within a month is hard to exceed the traffic, and I can do many other things. I will answer your question with my mobile phone now. It is strongly recommended to open the traffic, which is definitely worth it.
