ALL of Call FIlter needs to be free (not just the basics)!
3/4 of my calls are Spam & CF only catches half. To block the other half costs me $2.99 each on my 3 lines? Really? Another $100/year so I can adequately use my phone?
Spam is a massive industry problem causing many of us to question the viability of cell phones.
Solve this at a network service level and bundle it in. My $300/month I already pay should cover having a useable phone service.
