No app needed for SMS
Any saved contact can read back a one-time code.
Security first
Verify a suspicious call as it happens.
Send a one-time check while you're still on the phone: an SMS code to their saved number, or a push with a Confirm button in their Wcall.
The check can only be completed through the saved number or registered device. No confirmation - hang up.

Setting it up
Set up Wcall together
Scammers can fake a phone number or even a familiar voice - Wcall gives your parent a separate way to check.
Install Wcall on both phones and add each other to your Close Circle.
If someone calls pretending to be you, your parent's check reaches your registered device. Confirm or reject it with one tap.
Three moments where a pause matters
Scammers use urgency and emotion. Wcall gives you a moment of clarity and technical proof.
Urgent request for money
"I lost my card, please transfer 500." Pause. Send a check. True urgency can wait ten seconds.
A "Hi Mum" message from a stolen account
A familiar account writes on WhatsApp or Telegram asking for money. Check whether they really control the number before you reply.
The voice sounds strange
The caller sounds like someone close, but the voice, pace or request feels off. Send a check to the known number before acting.
How it works
Check any saved contact with an SMS code, or send a free in-app request to someone in your Close Circle.
Use an SMS code to check any saved contact. The other person does not need Wcall. They only need to read back the code sent to their saved number.
1
Open Wcall and choose the person the caller claims to be from your contacts.
2
Wcall sends a one-time SMS code to the number you already saved for that person.
3
Ask the person on the call to read the code back to you. Never tell them the code first.
Confirmed
This confirms access to the number, not the person's identity.
Not confirmed
Hang up β this could be a scam. Don't send money or share personal details. If it might really be them, call back on a number you saved yourself.
Add family members who use Wcall to your Close Circle. If someone calls pretending to be one of them, send a free check to their registered device.
1
Choose the family member the caller claims to be from your Close Circle.
2
Wcall sends a free confirmation request to that person's registered device.
3
They confirm whether they are calling you with one tap.
Confirmed
This confirms access to the device, not the person's identity.
Not confirmed
Hang up β this could be a scam. Don't send money or share personal details. If it might really be them, call back on a number you saved yourself.
Why it works
The call and the check travel over two different channels.
Wcall replies over a second channel: it sends a one-time check to the number saved in your own contacts - not to whoever is calling. Only someone with access to that number can complete the check.
No confirmation? No exceptions.
Scammers always have a reason why the check can't work:
- "My phone just died"
- "I'm calling from a friend's phone"
- "It's urgent - there's no time"
Every one of these means the same thing: hang up and call the number you saved yourself. If the request is genuine, they can confirm it when you call back.
Ending the call is not rude - it's safety. Pressure only works while you stay on the line; a scammer won't call back - they'll move on to an easier target.
Only a confirmation is evidence.
