Skype sends text messages, is there a charge for the bound mobile phone?

Yes, there will be a charge, and it is only free if the other party logs in to skype at the same time. No matter whether the mobile phone sends SMS to skype client or skype sends SMS to mobile phone, there is a charge, so be careful of the trap ~

I suggest your friend install skype on his computer. Chatting through this software is free. Please feel free to use it ~
