The company also offers a paid subscription service called Premium that provides enhanced features like the ability to block entire area codes and import contacts to block specific numbers.

The company claims its algorithm and crowdsourced database allows it to stay ahead of telemarketers and robocallers as they change numbers. But does the service actually work as well as advertised? Let’s take a deeper look at’s features and claims.

Effectiveness of Does it Actually Block Spam Calls?

The most important question about is simple – does it work? With over 100 million calls blocked, it would seem to be an effective solution. However, some users have raised concerns about the legitimacy and accuracy of’s spam call blocking capabilities.

One of the main issues cited by reviewers is the number of false positives where legitimate calls are erroneously blocked. This appears to happen most frequently with business calls as a store or doctor’s office may change their outgoing call ID which then flags it as a spam number to

The crowdsourced database only works well if users consistently report the spam calls they receive. If users don’t diligently report numbers, the database can quickly become outdated. However, the service claims to have measures in place to constantly identify and add new robocall and telemarketing numbers as they change over time.

Many users also complain fails to block obvious and verifiable spam calls that come through from clear robocallers. This suggests potential flaws in’s claims that their algorithm stays ahead of new spammer tricks and number changes.

Independent call blocking tests done by reviewers like CNET and Wirecutter found successfully blocked only 60-80% of spam test calls. While not perfect, that does represent a significant reduction in unwanted calls compared to using nothing. However, some competing services like Nomorobo and YouMail performed better in head-to-head tests.

Is Free or Paid? What’s Included in Each Plan? offers both free and paid subscription options:

Free Version Features

  • Crowdsourced spam call database
  • Online database lookup
  • Basic call blocking Android and iOS apps

Premium Version Features

  • Enhanced crowdsourced database
  • Area code blocking
  • Contacts blocking
  • Custom blocklists
  • Text message blocking
  • Call screening
  • Advanced call blocking apps

The Premium version costs $4.99 per month if billed annually or $7.99 month-to-month. Many of the features like contacts blocking and call screening require the Premium version.

For most individuals, the free service should provide adequate basic protection using the crowdsourced database. However, Premium may be worth the cost for the extra features and more aggressive blocking approach for frequent spam call recipients.

Both versions utilize the same underlying database. The paid Premium service adds additional call blocking features on top of the basic free version.

Can Block Calls on Landlines?

One major limitation of is that it only works for blocking calls on mobile devices. The service does not currently offer any way to block calls through a traditional landline phone.

Landline users can still utilize the free online database to check numbers and add numbers they want manually blocked by their phone provider. However, this requires contacting the provider directly instead of relying on’s apps and algorithms.

For a true landline call blocking solution, consumers typically have to use a third-party call blocking device that connects to the landline. Popular options include the CPR Call Blocker and the Sentry 2.0 Call Blocker.

Hopefully in the future will develop a call blocking solution tailored specifically for landlines. But at this time, the service only focuses on mobile call blocking through smartphones.

Can Block Text Messages?

In addition to blocking calls,’s Premium service claims to also block spam text messages. The Premium mobile apps allow users to report spam SMS numbers so they can be added to the blocklist.

However,’s text blocking capabilities are much more limited compared to its voice call blocking. While users have reported significant reductions in unwanted calls using, its effectiveness at blocking spam texts appears to be much spottier.

One issue is that many unwanted text messages come from email-to-SMS gateways which all share an common SMS short code. So blocking one specific number often doesn’t help when the spammers can instantly use a different shared gateway number.

Automated spam text blocking is also technically more challenging compared to voice calls. The content of a text message can’t be used to judge whether its spam in the same way a robocall using an auto-dialer can be flagged.

Can You Use on a VOIP or Virtual Number? is designed to work by blocking calls that come to your regular 10-digit phone number registered on the mobile network. But can it also effectively block unwanted calls on virtual phone numbers provided through VoIP apps?

The major issue is that many VoIP apps don’t provide access to the built-in call blocking interfaces on smartphones. Calls are received through the app’s own software which doesn’t integrate with’s apps.

However, some VoIP services like Google Voice do allow adding apps as an integrated call screener. In these cases, can successfully function to block identified spam calls from ringing through.

But for VoIP apps that fully manage their calls internally, won’t be able to automatically block them even if a spam number is identified. Instead, you would have to check the number against the online database and manually block within the VoIP app.

So compatibility with virtual numbers depends entirely on the specific app and whether it enables third-party call blocking tools. It’s best to check with the VoIP provider directly to confirm if will work or if manual screening is required.
