Getting started

The first time you log in to CaptionCall Mobile for iPhone (or iPad), you will be asked to acknowledge the limitations of E911 and verify your emergency address. You can update this address at any time in app Settings.

You can use the toggles to enable Touch ID or Face ID to use the app without entering your User ID and password each time.

Set up Call Forwarding

Call forwarding

You will receive another phone number with CaptionCall Mobile for iPhone (or iPad). While your regular iPhone mobile number will still work, only the phone number assigned by CaptionCall will allow you to use captioning. As a result, most users choose to forward their iPhone (or iPad) number to their CaptionCall Mobile Number. This means any incoming calls will automatically be captioned on your iPhone (or iPad). To set up call forwarding, go to Settings>Phone>Call Forwarding and enter your CaptionCall Mobile number, for Verizon customers, call *72 using iPhone (or iPad), enter your CaptionCall Mobile ten-digit number, tap the call icon and wait for the confirmation, “Calls will be forwarded to…”, then hang up. You can also contact your mobile service provider for help. Be aware that when you make calls with your CaptionCall Mobile number, that number will appear as your caller ID.

Making Calls

Calling 911

The CaptionCall Mobile app is a VoIP phone service. E911 service may be limited or unavailable under certain circumstances, including, but not limited to, uncharged/dead handset battery, lack of data coverage by your mobile carrier, or during an internet service outage. As part of becoming a CaptionCall Mobile customer, you provided CaptionCall with your Emergency Calling Service address. This address will be transmitted to the E911 center in the event that you call 911. If your actual location is different from the registered Emergency Calling Service address that you gave CaptionCall, you will need to provide your current location to emergency personnel when you call 911 during an emergency, or call 911 using your mobile phone service without captions. To verify or change your Emergency Calling Service address, please call 1-877-557-2227 or visit the Settings section of the app and touch Edit under Emergency Address.

Account activity

If you do not use CaptionCall Mobile for a period of 60 days, CaptionCall reserves the right to cancel your VoIP account associated with the app. If your account is canceled, you can sign up again at any time.
