NumShield: Caller ID & Block

NumShield is a phone app that answers the question every unknown call raises: who is this, and should I pick up? It is a call blocker, a call filter and your dialer in one app: see who is calling and stop the calls you never wanted before your phone rings.

Install NumShield and set it as your default phone app 2. Accept the permission disclosure so it can screen calls 3. Answer your phone in peace — spam and scams are blocked automatically QUESTIONS PEOPLE ASK • Is it really free? Yes. Every protection feature works in this version without a subscription or a trial timer. • Does call blocking work without internet? Yes. Screening and the offline spam database run on your device, so a blocked number stays blocked on a plane, in a basement or with mobile data switched off. • Will it block calls I want to receive? You set the rules. Favourites protection keeps the people who matter ringing, and you can allow, warn or block any number at any time. • Does it replace my phone app? Yes. Set NumShield as your default dialer and your dialpad, call history, contacts and in-call screen all live here. • Does it drain my battery? The spam engine only works when a call arrives — there is no always-on scanning process. • Which numbers does it cover? Numbers from any country, with community caller ID that gets smarter every time someone reports a scam. Stop answering calls you do not want. Install NumShield and send the spam straight to voicemail.
