How to send text messages to mainland mobile phones in Hong Kong is cheaper? Can I use Fetion or qq for my mobile phone?

In foreign countries, of course, you can use mobile phone Fetion and mobile phone qq, but you need gprs support, and the international roaming fee of gprs should not be low. Moreover, the current gprs monthly service is limited to domestic traffic.

At the end of 2007, I went to Hongkong, where the tour guide recommended a communication card, which seems to be a 200-minute mobile phone calling card from 60 yuan. You can buy one for direct use. It should be cheap.
