FAQs

How much does Robo Shield cost?

Robo Shield costs $2.99 per month and offers a 7-day trial of their limited free version — not the full app — when you sign up. You still have to enter your payment details before you can start the free trial, and you'll be automatically enrolled in recurring payments. If you only want the trial, you'll need to cancel your subscription at least 24 hours before the period ends to avoid being charged for a full month.

With Robokiller, there are no surprises. You'll get a free 7-day trial of the full app — not a watered-down version that hides features behind a paywall — so you can get an accurate idea of what we have to offer. Then you can continue taking advantage of the best robocall blocker around for $4.99 per month or $39.99 per year.

How does Robo Shield work?

Robo Shield blocks spam calls based on a global database of numbers that are known to be associated with spammers. Users can also block individual numbers in advance by manually adding them to their blocklist. Robo Shield directs blocked calls to voicemail, but they don't send notifications, so you'll have to check your voicemail to see if it's working.

Does Robo Shield stop spam texts?

No, Robo Shield does not protect its users from spam texts. This is unfortunate because scammers can use spam texts to steal personal details like your bank account or credit card information, ultimately co-opting your finances. All it takes is one smishing link to lose your financial stability or even your identity.

Fortunately, Robokiller has your back when it comes to robocalls and spam texts alike. Our comprehensive spam text protection shuts spammers down from all angles, keeping the fraudsters out of your inbox.

Is Robo Shield an effective spam call blocker?

Users should be aware that Robo Shield is unable to block calls listed as restricted, private, unknown, or anonymous. The app is also unable to block shortcodes (five- or six-digit numbers). The free version of Robo Shield will identify spam calls but still let them through, which means it will warn you about spam but it won't do anything to protect you from it.

Does Robo Shield work on my phone?

All spam blockers have some kind of tech requirements, but Robo Shield's are especially stringent. The app is currently only available for iPhones that run iOS 11.4 or higher and is only available in the U.S. and Canada.

The good news is that everyone has access to the spam blocker they really need: Robokiller. Our top-of-the-line robocall and spam text squasher is available worldwide on both iPhone and Android devices.
