The TalkBand B2 supports caller ID display.
If the caller ID can't be displayed, you may have denied the TalkBand B2's access to your contacts on the phone.
Every time your TalkBand B2 is connected to your phone, a phone book access request dialog box will be displayed on your phone. Touch Yes to allow the TalkBand B2 to access the contacts on your phone.
If you touch No, delete the TalkBand B2 from the paired device list on your phone, restart the TalkBand B2, and pair it with your phone again.
