bearone21, that is correct we now have a free version of call filter available. You can also get the service through My Verizon. Please see the link for details.
Both the phones on my account show as compatible devices (iPhone XS Max and Galaxy S10). However when I go the the "Get it" page, I get a message that says Sorry, one of the phones on your account is not compatible. So what's up?
It concerns us to hear you're experiencing issues when trying to add Call Filter to your lines. We always want to make sure you're able to add any features that will benefit you, and we'll do everything in our hands to help. We have some questions to better assist. How are you trying to add the feature to your lines? Are you able to add the service to the other cell phone?
If I use the link "https://www.verizonwireless.com/solutions-and-services/call-filter/" and then "Get it Now", I get a popup message that says one of the devices on my account is not compatible.
If I try by going to the web page for Add-ons, I can select the free option, however I cannot select the Samsung S10 on line ending 01. I can select the iPhone on line 00.
If I check the list of supported devices, both the Samsung S10 and the iPhone are supported devices.
If I download the app from the Google store to my S10, the only option available is to subscribe for $2.99/month.
