So, the story is: I went to Sri Lanka and bought a Sri Lankan sim and when I put it in, my contacts went. When I put my regular sim back, the contacts didn't come back. I tried many contact recovery apps on the app store, but no luck. The only thing that did work is wondershare. It showed me my contacts but to recover them, I need to pay. Is there any free way I can fix this? Or should I just do them manually?
