Yes, certainly :)

But first you will need to move or copy these contacts from the SIM card to either your device itself or one of the popular cloud providers (iCloud, Gmail, Outlook). While it is good practice to do this anyway (among other reasons, in order to be able to recover your contacts if you lose your phone), the reason why Covve doesn't work with SIM contacts directly is that SIM cards are very limiting in terms of the data they can hold when it comes to contacts.
