My single greatest App Store purchase.

For years I’ve fought with AT&T and spam callers from one area code. This solved it. Just today it blocked over 30 spam calls.

App doesn’t work, Customer Support won’t respond

App keeps crashing, won’t load numbers. The FAQ page refuses to load. I contacted customer support, but they don’t reply back. Looks like I got ripped off, nothing else I can do except leave a 1-star review.

Great app

It works

Amazing

This app lets me do what Verizon refuses to: block specific area codes that i get 10+ spam calls a day from. Verizon wants me to pay an additionally monthly fee to block just 10 "neighborhood codes"(the first 6 digits).

Number shield just let me 6 area codes i get all my spam from. Number shied let me block 6+ million numbers for a one time payment of 2.99! Verizon wanted me to pay 3.99 A MONTH to block just 10 neighborhood codes(6 digits) thus only 100,000 numbers. Number shield is doing what verizon refuses to. This service should be provided by verizon for FREE but i had to find a third party app to handle this. Thank you for this great, fairly one-time-prices app. 10/10 amazing

WOW. Spam has dropped a lot

So this may sound bad, but I have only had 23 spam calls for the first 20 days of May, but that is down from over 60 a month. I usually get 2-3 a day from similar exchanges. Now I block them and my spam calls are a third of what they used to be.

International spam has completely stopped. Great program.

UPDATE: I have been using this app for years. I don’t get nearly as many spam calls as I used to. However, my spam text messages have skyrocketed. When there is a pattern, I have started blocking the exchanges for spam texts and those are dropping. The only problem is that spammers are constantly changing numbers.

I’m still happy with the results.

How do I block similar numbers?

You can block similar numbers by entering a wildcard for each digit you want to block. For example, to block numbers similar to 714-555-1234, you could enter 714-555-####. You can also block numbers directly from your missed calls screen by sharing the contact and selecting 'Block Similar Numbers'.

Is Number Shield free to use?

What happens to blocked calls and texts?

Blocked calls are automatically sent directly to your voicemail. Blocked text messages are sent to the 'Junk' filter within your phone's Messages app. Please note that iMessage messages are not blocked.

Can I still receive calls from my contacts?

Yes, phone numbers that are saved in your contacts are always allowed. This ensures you will not miss important calls or messages from your family and friends.
