Contacts don't show in Outlook contacts

[LGDP]

Hello,

Here is my problem :

I used to have nokia phone where all my contacts were stored on SIM.

First name and last name were in the "Last name" field.

Now I have a LG KS20 phone and I copied all my contacts from SIM to Contacts.

Now I see only the phone numbers in my contacts because it is checking only for "First Name" field which is empty.

Is there any program I could use to move the "last name" field to the "first name" field for all my contacts?

Please let me know if any other suggestions..

Thanks!
