Can I help you , Ma'am ?   I need a phone card for this new cell phone .   Cool phone . What kind of phone card do you want ?   It's for my daughter who is still a senior high school student .   Then the M-Zone will be suitable .   What's special with the service ?   You know students use tested message service . And they provide favorable service for that .   That's nice . And I need a pre-paid phone card .   Oh , there is a sales promotion for it now .   Oh , good . Then what is it ?
