Does the ClearCaptions Mobile app need to be open for me to receive a call?

No. Even if your phone or tablet is in sleep mode or is locked, when you receive an incoming call (either from a caller who is dialing your ClearCaptions Number or from a caller who is dialing your mobile phone number that you have previously forwarded to your ClearCaptions Number), your device will indicate you have an incoming call. When you respond to the call, you’ll see the ClearCaptions Mobile app icon; tap it to receive the incoming call with captioning.

FEDERAL LAW PROHIBITS ANYONE BUT REGISTERED USERS WITH HEARING LOSS FROM USING INTERNET PROTOCOL (IP) CAPTIONED TELEPHONES WITH THE CAPTIONS TURNED ON. IP Captioned Telephone Service may use a live operator. The operator generates captions of what the other party to the call says. These captions are then sent to your phone. There is a cost for each minute of captions generated, paid from a federally administered fund.
