Description
Tired of spam calls from the same area codes? Take control of your phone again. Spam Fortress lets you block hundreds of unwanted numbers at once by targeting their area code - no need to block them one by one. Your contacts always get through, and blocked calls go straight to voicemail.
How It Works Add spam-heavy area codes to your block list (like 800, 888, 877, 866, 855, 844, 833), and the app automatically screens all incoming calls. Contacts are never blocked. Voicemail and text messaging work normally - you'll never miss emergencies.
