　　It looks like a mobile phone, but the service is much cheaper ．It acts like a mobile phone, but only in your own cite ．Beyond the city walls, it’s useless．

　　“Little Smart”, also called“xiaolingtong”has always been compared to the mobile phone．But in fact it is more like one of those cordless phones(无线电话)used around the home．The only difference is that this one reaches much further than from the bathroom to the living room．It can travel across a whole city．

　　Cheap costs are the main reason for the success of Little Smart．It costs 25 yuan a month for the line and about 0.1 yuan per minute to use．A mobile phone, on the other hand, can cost four or five times as much．What’s more, unlike mobile phones, there’s no fee for incoming calls．So these low charges have attracted many users．

　　But, Little Smart is not really that smart．Users often complain about its bad voice quality(质量)．And there are not as many questions to pick up its signals as there are for mobile．“I couldn’t receive a photo call if I was on a bus,” said Li Ping, a user in Hang Zhou．“It worked fine when I stood still, but there were breaks in signal when I was moving．”

　　Scientists are trying to make Little Smart more easy to use．Messaging and Internet even has a colour screen．
