How can I send text messages cost-effectively? I send almost 1,400 text messages every month. Is it more cost-effective to subscribe to monthly SMS or mobile QQ or Fetion?

Get a WAP Internet package and chat with QQ on your mobile phone. There are 5 yuan, 10 yuan and 20 yuan. I used to use the 20 yuan package, which had unlimited traffic. However, this package has now been cancelled, and has been changed to 20 yuan for 50M traffic. If you only use it to access QQ, the 5 yuan package is enough.

However, it only works if the person you are chatting with is also using QQ on mobile phone.

Obtain a wap Internet package. There are many free text messaging apps available for mobile phones. Like X-Rose; PINGCO are both good. But you need to participate in interactive activities to earn points before you can send text messages. PINGCO supports text messaging with China Unicom users. I've used it before, it's good.
