The default storage location for saving phone numbers to your contacts is your phone's built-in memory. As soon as the SIM card is inserted into the handset, the phone synchronizes the Contacts (using the Mobile backup feature) to the T-Mobile network. Additionally, new contact information is stored directly to the phone's memory and synchronizes with T-Mobile's network during predetermined, timed intervals.
