Ok, I've found and tried this path from the Contacts app. A little bit long this route. More large if you are in a call and wanna call another contact (+Menu -> Contacts -> ...)

Steps to reach a call:
1. From desktop, touch a Contacts icon
2. Touch out of the "Obtain contacts" dialog
3. Touch "All contacts"
4. Touch "Groups"
5. Touch "Sim card Contacts"
6. Touch a contact
7. Touch "Dial"

* In bold the steps caused by the lack of SIM card integration.
* If the user have selected wrong a contact, may not see the mistake, because in the phone only the number is shown (not the name)
* The calls history in the Phone App only show numbers, not names.
