You can delete SIM Card Contacts from your BlackBerry Storm smartphone like this:
1. From the Contact list, press Menu.
2. Select SIM Phone Book.
3. Highlight a contact.
4. Press Menu.
5. Select Delete.
A common question asked is ‘How do you delete multiple contacts from the SIM card at a time?’. It looks like there is no way to remove multiple entries though. Perhaps there is a third-party solution out there? If so, please post it.
