Each person needs the HiSign app on their own phone.
Add each other in person by scanning each other’s QR codes or using NFC.
Read the words under “You say.” Compare what you hear with “They say.” Your contact does the same.
Send a little invitation now. Bring both phones when you meet, add each other, and try a call.
Make a family call plan →Yes. Each person needs HiSign on their own phone. Add each other in person before you need to check a call.
The supporter purchase is optional and one-time. It does not increase the 50-contact limit or change the phrase-check security model. The store shows the current local price.
Keep the call open and switch to HiSign. A headset or speakerphone can help you read the screen while talking. Open your contact, read “You say,” and compare what you hear with “They say.” Practice together before you need it.
Pause the request. Call back using a number you already know, or contact someone else you trust. A mismatch or an unavailable phone is a reason to follow your agreed plan; it is not by itself proof of a scam.
