Is there a charge for sending private messages on WeChat?

Software development companies will not charge any fees, but there will be traffic charges during the use of the software. This is the fee charged by local mobile operators. If you handle the traffic package business, you don't have to worry about the high traffic fee. It is recommended that you apply for a suitable traffic package when using WeChat, otherwise high traffic charges will be generated during the use of the software. In other words, if you use WeChat without a traffic package, you will be stabbed by the phone bill at the end of the month.
