Who has used Ding Dong VoIP?

Although it's been 10 months since you asked questions, let me talk about the Ding-Dong telephone.

I'm using it now, but I don't use it often. It is not cheap to make a domestic call at 2.2 Ding Dong dollars per minute in China. Ding dong coin is one yuan. I applied for an American mobile phone number and used 100 Ding Dong dollars. It's not cheap to answer the phone with this mobile phone number on the app. It is difficult to earn Ding Dong coins. You can't earn a few a day. There are often mistakes in the activity and I can't open it. You can answer calls from American mobile phone numbers on the app. The effect is ok. There are very few apps in China that can take over the phone number, and they all make calls through VoIP.

Ding-dong VoIP, in short, it's ok.
