Comparison is the best way to identify one's usefulness. And it is human nature to compare two things or services to decide which one is the best. In the domain of communication, numerous network providers are available (eg T-Mobile, Vodafone, Orange, O2, 3G, Virgin etc)., with their different and valued offers plus deals. Everyone is competing with one another to remain at the top in the market. As such, they all are trying to catch the user with their lucrative gifts and offer for the fresh user. But 'Mobile phone upgrade' can make the people truly loyal with their network providers. The reason is that same lucrative offers are being offered to them as other ones are giving. The difference is that users can continue with the previous network service without changing their older lucky phone numbers. But turning to another provider may get them new number. The network service providers are highly benefited by maintaining their existing users rather than getting new ones. Enjoying free mobile phone bonuses and gifts may stop the user to move towards another service. It would be much better to be the older user of old network rather than to be the new user on different network.
