Beware! This app quietly charged me 49 NOK every month through my Ice mobile invoice, and I didn't realize it for four months. I uninstalled the app almost immediately, but the charges kept coming without any clear consent. When I finally reached out, the support was dismissive and unhelpful until I got serious about the refund. It’s a total scam that hides fees in your phone bill. Avoid at all costs!

This app is a scam. They charge you without warning just for downloading the app! Ridiculous. I Uninstalled the app after one minute when I realized they required you to buy a subscription to actually see who calls. NO WHERE did I accept paying for their service and now suddenly I get a bill in the mail. DO NOT download this app!

Hei! Takk for tilbakemeldingen! 1881 Mobilsøk er en abonnementsbasert tjeneste uten reklame. Du har 30 dager på seg til å stoppe abonnementet ( send "stopp mobilsøk" til 1881) og du har tilgang ut gratisperioden. Ønsker du en gratistjeneste har vi 1881.no både på app og nett. Mvh Opplysningen 1881

Useless. Installed, requires loads of permissions, does nothing to identify the caller. Have had 4 calls from I wanted this to know about since install, nothing. Regret installing, wonder if they mined my contacts. Apparently after the free period is a paid period. No chance.
