Where has my phonebook transferred from old flip phone to Lumia 635 downloaded to?

[Windows Central Question]

Phonebook transferred from old flip phone to Lumia 635 has disappeared.

I had my 100+ phone numbers on non-SIM, non-smart flip phone (Samsung M370). Just bought Lumia 635, paired both via Bluetooth, and transferred the phonebook (names and phone nos.) to the cell phone. Now I can't find them, so I can't call any of my contacts using those numbers. Please help.

Not 100% sure but may be it can sync in your Microsoft account. You can logged in your Microsoft account and check your contact list.
