Fails on international calls

Love the app except it doesn’t work on international calls because they have longer phone numbers. I don’t want to have to pay for the premium version if it won’t block these calls. Is there a way to get this option?

Will Not Allow Me To Block Calls

The app doesn’t pick up all of the calls, many have to be manually blocked! The app will also at times indicate a call can not be blocked! Then what do I do? I receive at least 10 to 15 spam or robo calls per day!!! Having to manually block calls on the app is tiresome. Very poor app! I really need help but can’t get it! Tried calling US Cellular- no help there! They referred me to the app developer-no help there, only a voicemail to leave a message after spending over 30 minutes on the phone with US Cellular. And I’m a paying customer for this app and US Cellular!

Developer Response ,

If you have the Premium version, you can have spam calls go straight to voicemail. Also know that US Cellular blocks the worst spam calls at the network so you never see/hear them. Other spam calls can be "blocked" by enabling blocking in our app.

Call Guardian update not working

I updated the Call Guardian app, I guess, because it told me my basic version was out of date. I went to App Store and all it says is open app. When I want to check to see if a number is legitimate or a spam, I can’t check anymore. I went to settings and checked to make sure call blocking is on, turned it off and then turned it back on. This still did not fix the issue. All I get is a page that says report spam or make a contact card. What happened to the ability to check numbers?

Developer Response ,

Hi, the functionality you describe was not removed, it is still there. To check and see if a number is a spammer, go to the Search tab in the Call Guardian app and type the number in. We will do a real time lookup against millions of spammers.
