Shield: Caller ID & Block Spam

Shield blocks telemarketing, spam calls, texts, and unwanted emails while delivering automatic Caller ID so you know who is calling before you answer. You can search numbers later and report new nuisances to strengthen the community registry, with easy blacklist/whitelist controls.

With Freemium and Premium plans, Shield offers flexible blocking options, an ad-free experience, and ongoing updates to the known spammers list. Premium includes unlimited blocking and extended settings, plus Caller ID powered by the Suomen Telemarkkinointiliitto database. A 15-day free trial lets you try before you buy, and Shield never sells your data.
