1. Your package is in the form of GPRS20 yuan package, which can't be changed to 5 yuan (20 yuan contains 150M traffic), so you don't need to apply for 5 yuan package, and it's impossible.

2. In addition to giving away 150M traffic, this package also gives away 300 domestic short messages, caller ID, Fetion and 139 mailboxes (free version).

3. 150M traffic, not to mention hanging QQ into the space, playing a mobile online game is enough.

============

There are also the 30M package in 5 yuan and the 150M package in 20 yuan, both of which are used for surfing the Internet, but the given traffic is different. Each mobile phone card can only open one online package every month, because your online chat package is a gift from 20 yuan (including 150M), so you can't open other online packages, so you can only use 20 yuan's 150M package, which is a gift from the package.
