Android users, see information here. iOS users continue below.
Your Signal contact list will only show users who also use Signal and are listed in your iPhone Contact's app.
You will need to give access to your address book to add a phone number or add a specific contact. If you need to re-enable access you will need to go out of the app and go to one or both of the following:
- iOS device Settings > Signal > Allow signal to access contacts
- iOS device Settings > General > Restrictions (if On)> Contacts and select Allow Changes
If your Signal contacts are not showing up, please store numbers in your address book in the correct E.164 format (i.e. with the + and excluding initial 0's). If a contact sends you a message, and they show up as a number and not the contact name you can see how their number should be formatted in your address book.
To refresh your contact list tap on the message compose icon or + in the top right corner and then pull down on the contacts list page.
If you are still not seeing your contacts, have you confirmed they are using Signal?
