Mobile phone plans are usually pre-paid or post-paid. The best plan for you depends on your usage. If you already have a pre-paid or post-paid mobile plan and would like to move to a better plan, first find out your usage before looking for a new plan. Go through your usage history as far back as it is relevant and determine your usage pattern. Your service provider usually sends you your monthly usage with your invoice. Don't throw away your usage data as it comes handy when you want to change your provider. If you don't have your usage history, you may still get all your usage history by logging into your service provider's website and going to your account information section.
