Facebook's new Messenger app now lets you sign up with only a phone number, sidestepping the need for a full Facebook account. The docs are a bit sparse for those who want to be informed before signing up, so...
If I sign up for a messenger-only account with a phone number:
- How am I discoverable by users with full Facebook accounts? (I.e. will they need my phone number to find me, or can they look me up by name in the global graph search and see my picture?)
- And how can I discover other contacts on the Messenger app to start chatting with them? (I.e. will the contact search bar search only contacts whose phone numbers I know, or will it search the global Facebook graph too - including Facebook users without phone numbers?)
This seems an obvious enough thing to be in the messenger.com docs, but astonishingly this does not yet seem to be there
