How much does it cost for A and B to send messages to each other by PC Fetion in the United States and China?

1, yes, no charge;

2, yes, it seems that B only charges 50 cents, not even a dime;

3. If A is in America, A must go through international roaming, otherwise B can't get a reply. If A has international roaming, it is theoretically free to receive short messages, while B sends them to Fetion, so it only costs 50 cents.

That is to say, in which country Fetion is located, it is a concept with domestic Fetion, mainly depending on where the B mobile phone is, and the PC client logs in when it logs in, regardless of the region.
