Twitter's use for SMS sending and receiving
Hong Kong is unique in the sense that whilst we have insane mobile penetration of 154.4 %, there is a huge price difference between voice plans and SMS plans.
Depending on a third party long distance provider, it is actually cheaper to call up somebody and speak for a few minutes (HK-US charges are 7 cents/min and an SMS costs at minimum HK$ 2) and convey more than send a SMS to that person
Thus, I find Twitter’s SMS integration very useful. I tell my family members to sign up to Twitter and then also enable their mobile devices. In India, Twitter has a shortcode 5566511.
In HongKong, wifi access is very ubiquitous via the GovWiFi program as well as efforts by FON as well as PCCW, HongKong’s dominant telco provider so hopefully with the upcoming launch of the iPhone in Hong Kong it can help me by allowing me to have access to Twitter
