Lost half my phone contacts

[usertNcaAhaEad]

All of a sudden all of my phone contacts before the letter N have disappeared. How do I get them back?

Thx

Did you back up your contacts to pc through Samsung Smart Switch or copy all to sim card ?

If they did not back up, time to hit the yellow and white pages.

I found lost contacts with +signs beside them. What does that mean? Before I click on the name.
