Their goal is to ensure effective and smooth communication." — Verified user "I was able to make a phone call myself. I set up my own appointment. I could clearly read every word the recipient was saying to me. I explained to her I was deaf and I was using closed captioning. It was amazing. Thank you Rylo for allowing me to be more independent." — Verified user Download Rylo. Make calls with confidence.

There is a cost for each minute of captions generated, paid from a federally administered fund. There are also eligibility requirements and a cost, paid by a federally administered fund for each minute of IP Relay service. Emergency calling through Rylo works similar to, but not the same as, calling 911 directly through a landline. It is important to keep your Rylo Registered Location updated.
