Contacts Synchronization if I don’t have Inbox contacts
If you don’t have any contact on the inbox web version (inbox contacts), then after confirming contacts synchronization at the first time of authentication in the mobile application inbox.eu, all contacts who are in your mobile phone’s address book (regardless of provider type) will be automatically added to the inbox contacts section. Contacts, which are stored in the same phone on Gmail, Viber or other places - will automatically appear in the inbox contacts section.
After these activities, at the mobile phone address book, next to imported contact you will see inbox icon.
(!) After exit (logout) from the inbox mobile application, all synchronized contacts from your mobile phone, will remain at the inbox contacts (web version) folder "From Android".
(!!) When you are editing the contacts on your mobile phone, do not forget to make changes to all providers who store information about this contact.
