Cross SMS contact issue

Skype is good. uuCall is also available. You can buy a small account on Taobao or Paipai (the kind that can call for dozens of minutes and has a validity period of about a week), which is very cheap.

It is said that Fetion allows you to send and receive text messages free of charge, and only charges traffic charges. You can get a mobile number in China, open Fetion, and get a monthly GPRS traffic subscription. The charges vary from place to place.

If everyone had access to the Internet, wouldn’t it be better to use QQ voice and video chat?
