The Secret to Blocking Scammy, Spammy Calls from Telemarketers

Services for Real Estate Pros with Inc

If you are someone who gets spammy, scammy calls, you are not alone. You also know that they can be very annoying. Thankfully, there are a number of apps out there that can help. Here are a few of the best:


CallApp can be used to lookup numbers, and then you have a choice to pick up or not. It collects data from its users, and then passes on the info to you when a call comes through. CallApp Crawler is available for Android phones.

Call Control

The Call Control app allows you to block calls, do reverse look up, and even blacklist texts that are unwanted. It is easy to use, and the community supplies spam numbers to keep all members safe from scams. You can get Call Control on both Android and iOS phones.

Calls Blacklist

Calls Blacklist is another option that allows you to block calls, but also offers things like filtering calls by prefix. This means that you can block out all numbers that start with a certain prefix, like 803. You can only get this app for Android phones.


Previously, Hiya was a simple reverse look up app, but now it also offers features like caller ID and call blocking. The app also has access to billions of records, including your own number. Hiya is available for both iOS and Android.

Norton Mobile Security

Norton Mobile Security is another option, but it isn’t necessarily an app that blocks calls. Instead, it’s a full security app that has call blocking as part of the features. This app is a great choice for people who want full security software on their phones, and it is available for both Android and iOS.

Safest Call Blocker

Safest Call Blocker is a simple app, but it is still very effective at blocking any and all unwanted numbers from telemarketers and robocallers. Just. Keep in mind that right now, it is only available for Android phones.

Should I Answer?

This is an app that looks up numbers, blocks calls, and categorizes it all to make it easy. There are more than 500,000 numbers in the data base, and you can get it for both Android and iPhone.


This is one of the more popular call blocking apps out there, and it has a data base of more than 2 billion numbers. This is a great app for identifying spam numbers. But, you must keep something in mind. TrueCaller has all of this information because it also adds its users numbers to the list. This app is available for iOS, Android and other operating systems.

Some good information here.  The spammers are out of control and do not respect the Do Not call lists or even what time of day they call

I recently started blocking emails instead of "unsubscribing".  Sometimes, when you unsubscribe, it verifies you had a valid email and it backfires into even more spam!  Also, some hackers are getting so creative that their link to their malware looks like it is the "unsubscribe" link.

Thanks for some great information, Robert. The scam/spam texts, emails and calls are getting ridiculous.
