Even if your cell phone is prepaid, you should still be able to access your call log. Some argue that this is a function that is only available for contract cell phones, or post paid phones, but all phones should have a function built within them to access this data. Typically to access a call log on your phone you will first have to enter the menu. Within this menu there will be an option labelled 'call log', 'calls' or something similar. A Blackberry, for example, has its call logs stored under the 'Phone' menu option. Most modern cell phones will have a shortcut to the call log that can be accessed by pressed the green 'call' button. This is the button that you will normally press to call a number that you have typed into your keypad.
If you want to access more information than just who you have called and when, e.g. Find out how many minutes or how much credit you have remaining, most network providers give you the option to do this online. By setting up an online account with your network provider, you should be able to access the details about your phone's usage. Within your account there will be a 'View Bill' option. Through this 'View Bill' option you will be able to see exact details about any phone calls you have made and how much of your prepaid credit each call has used. You will also be able to check your remaining prepaid balance and add more credit to it if you feel it is necessary. Being able to access these in-depth details of your phone's usage allows you to see where the concentration of your credit is going to help make future decisions about your contract. This information can also be used should there be any discrepancies in your bills.
