Many different factors should be involved in selecting a mobile phone. The most important are features and price. Essentially, you want to get the features you need, but not pay for features you won't use, at the best price possible. If you are living with your parents, you should also look for family plans which can significantly reduce the cost of a phone. Another issue is durability and reliability. Consumer organizations such as Consumer Reports publish comparative studies that serve as good guides to this. To avoid being locked into a specific provider, look for a fully unlocked phone that can accept sim cards from any company rather than one that locks you into a plan from a single phone company.
