Spam blocking that lets the people who matter through.
Birln Wall screens your number. People you know ring straight through. Strangers pay a one-time $1.99to reach you — so robocallers and spammers don't bother. Your real number stays private.
Coming soon to iPhone and Android.
How it works
Three steps. No more guessing who's on the other end.
Get your Birln Wall number
Hand out a screened number instead of your real one. Your personal line never shows up for callers you haven't approved.
The right people ring through
Add the people you know to your list. Their calls and texts connect instantly and free — they never see the screen.
Strangers pay to reach you
Unknown callers are asked to pay a one-time $1.99 to connect. Real people pay it; spammers and robocallers move on.
Your number is yours again.
Birln Wall puts a wall between your real phone line and everyone you haven't approved — without missing the calls that matter.
- Your real number is never shown to unknown callers.
- You decide who's on your approved list — change it anytime.
- We never sell or share your number, contacts, or messages.
- Payments are handled securely by Stripe. We never see card details.
Take back your phone.
Get Birln Wall and let only the people who matter ring through.
