What is WAP and what is JAWA?

China Mobile artificially divides gprs into CMWAP and cmnet, which are what we call WWW and WAP networks. CMNET is faster, and the price is 3 cents /kb. At present, wap monthly subscription is generally not limited to traffic, but you'd better call 10086 to ask if there is an upper limit for traffic. The monthly fee is generally 10 yuan to 20 yuan every month.

After WAP, you can hang QQ on Monternet's dynamic e-home (WAP. Monternet. com), and there is no charge for accessing 163, 126 and Yahoo Mail. If your mobile phone supports jave, you can go to wap.ucfly.com to download ucweb cracking software (free download). You can browse the www page for free through this platform, and there is no charge for downloading mp3 on the www (note that you can log in to www through ucweb).

There is no charge for downloading things on some WAP websites. I recommend a website for you:

wap.hao 123.com

This is a website providing links, in which Skynet, wap World and Dynamic Network are all free and can be downloaded with confidence. The others are not clear. Pay attention to the tips yourself, and be careful that there may be information fees.
