Mobile phone functions are also being used in schools. In France, schools are using mobile phones for exam revision. In Australia, Brisbane University is using SMS to help foreign students learn English. Information that explains grammar is sent to their mobile phones between lectures. In China, the BBC has teamed up with Sina.com to provide English learners with similar opportunities so that they can learn English while traveling to work. What of the future? It has been predicted that mobile phones might soon replace our wallets. For example, instead of handing over cash to pay for groceries, our mobile phones would be scanned and the cost added to our next phone bill, the idea that in the future we won't need to carry money seems crazy, but 80 years ago, the idea that you could walk out of your house with your phone in your hand probably seemed more crazy! Mobile phones have become a major part of our lives and one wonders what the next technological advance will be.
