How do I save contact details on my Nokia phone?

In the phone memory you can save different types of phone numbers, a tone or a video clip, and short text items for a contact.The first number you save is automatically set as the default number and is indicated with a frame around the number type indicator.When you select a name from contacts (for example, to make a call), the default number is used unless you select another number.Make sure that the memory in use is Phone or Phone and SIM. Select Menu > Contacts > Settings > Memory in use. Select Phone and SIM to recall names and numbers from both memories. In that case, when you save names and numbers, they are saved in the phone memory.Search for the contact to which you want to add a detail, and select Details > Options > Add detail. Select from the options available.
