it depends on the person needs and requirement as a student don't need to have a mobile phone with them but speaking about you should definitely have a mobile phone with you,because it may help you to make fast appointments and meeting status .
I do agree with link press. It depends on the person needs and requirement. There are some people who always need mobile to contact with others like businessmen, marketing people but other like students don't need mobile phones. It is also important for people to know proper mobile etiquette.
Be very, very careful. It looks to me as if your teacher has sprung a nice trap for you: you are not requested to argue that it's a bad idea for children to have a mobile phone, you are requested to argue that it is not compulsory. Some of the earlier answers seems to have missed the distinctions. For example, you'll be shooting yourself in the foot if you say that "it is not compulsory to have a mobile phone because it can cause brain cancer"
Yes mobile phone is the compulsory thing of the today's life, I can say that it has become the part of life. Because technology has been growing up so much that now most of the work of daily life gets done with just a click on your mobile phone.
I totally disagree with having young kids walking around talking and texting on the cellphones all the time, especially if they don't have a driver's license yet or if they don't have a job to pay for them.
Business people, or online workers need to have access to their work to be able to manage it when things need to be dealt with. Micro job workers, for instance, should have their own mobile device so they can check for orders and messages in their inbox, as doing this simple task will keep help with keeping their response time down.
I tend do check in with my accounts to avoid lengthy wait times for my customers
Yes, according to me my view it is compulsory for everyone. But it should use as per the need. Now a these days it has become a part of the life. We can communicate with anyone in just few seconds. Even we can do our business in wide areas as well.
