It is old news already, but I think it is valuable information to visitors to Shanghai. China Mobile has decreased the price of GPRS. They are offering a package to give unlimited WAP access for 20 RMB per month. Here are the configuration details:
Access Point: CMWAP
CMWAP v.s. CMNET
I have been using GPRS from China Mobile for some time but I never really understand the difference between the two AP – cmwap and wmnet. The only thing I know was, to be able to access Internet, for example, from my laptop, or Dopod Smartphone to access Internet website like ebay.com, I have to use cmnet. If I only need to access WAP site, like WAP comment feed for this site, cmwap is enough. CMWap is cheaper – 20 RMB for all-you-can-eat while CMNET is charged by bytes.
You need to answer the question in the configuration section of your mobile.
Now, I understand the situation better.
CMWAP and CMNET are intentionally divided by China Mobile. They are two access points. If you configure your mobile to access CMNET, your mobile phone is assigned an IP address and the client can directly connects to web servers on the Internet, like microsoft.com, yahoo.com, wangjianshuo.com…
CMWAP is an application layer seperate that your client is assigned an IP address in the range of 10.*.*.*, and you can ONLY access sites with IP addresses in this range. That means, only the servers hosted by the closed system in China Mobile. There is one exception though. It is the mysterious 10.0.0.172 configuration. That is the ONLY WAP gate server on the 10.*.*.* network range. With this WAP gate way, you can access all the website (like a proxy) on the Internet that provides WAP protocal, like Wangjianshuo’s Blog WAP Edition. However, it is slow since there is only one point that you can access for the entire China Mobile.
So, just call 1860 to enable your unlimited WAP access today. :-) (Seems I am a China Mobile agent now).
