Android - How can I see only phone contacts, not SIM contacts?

I solved this by erasing all contacts on the SIM. Here's how:

1. Contacts app -> Menu -> View. Uncheck all but SIM, press OK.
2. Menu -> Delete.
3. Menu -> Select All.
4. Press Delete.

After a while all SIM contacts are gone. Now re-enable showing the Phone and/or Google contacts and you're good to go!

(My phone uses Swedish so maybe the menu items/buttons above have other similar names)

Go to contacts -> press menu button and choose more -> then display options -> there you can choose either SIM or Phone. And say DONE

Try this SIM Contacts Manager application from Android Market. It is going to manage all your contacts which are in SIM card.

There is one more possibility of having duplicates in your contacts list. If you are importing/synchronizing the Contacts from Facebook/Gmail/Twitter then it will show the contacts twice or more. In this case use this Contacts Merger which merges the duplicate contacts.
