## Number Shield Description
Block annoying scammers who hide behind fake phone numbers.

Do you get unwanted calls or text messages from phone numbers similar to your own?  With Number Shield, block an entire group of numbers at once.  Just enter a wildcard for each digit you want to block.

For example, if your number is 714-555-1234, scammers might use a number like 714-555-6789.  Block all similar numbers by entering 714-555-####.  Wildcards and numbers can be combined in any order you choose.  Block international numbers, too!

To make sure you don&#039;t miss calls from your family and friends, phone numbers in your contacts are always allowed.

Block numbers directly from your phone&#039;s missed calls screen.  Just follow these steps:

1. Tap the “ i ” button next to the missed call.
2. Tap “Share Contact”.
3. Tap “Block Similar Numbers”.  (If you don&#039;t see this action, tap “Edit Actions...“ to enable it.)
4. Now you&#039;ll see the Number Shield number entry screen.  Tap “Done” to block calls from similar numbers.

Please note:

• Each number pattern can contain up to 7 wildcards, and up to 50,000,000 phone numbers can be blocked.
• Blocked calls are sent directly to voice mail.
• Blocked text messages are sent to the “Junk” filter in the Messages app.
• iMessage messages are not blocked.
• When “Do Not Disturb” is enabled on your phone, calls that should be blocked may appear in your phone&#039;s list of missed calls.

More information about caller ID spoofing in the United States is available from the FCC:

## Number Shield Reviews in United Kingdom

### *---- "Mike Pollard"
Really disappointed with this app. I get dozens of 0843 and 0845 calls a week, sometimes 5 a day and this app does not block them. If they are accidentally answered they can cost a £5 connection fee, quite apart from having to stop what you are doing to look at the call. If it won’t stop these premium numbers, then what god is it?
-- Forestlander, 2024-12-12

### *---- "Doesn’t reply to support email"
Doesn’t work in the UK. Emailed support three times and no reply. Requesting refund from Apple.
-- happyboyblue, 2024-11-19

### *---- "Very disappointed"
I get repeated calls from 0843, 0844 and 0845 numbers. The remaining digits change randomly. The phone rings once and stops. If you call back you get charged and it’s a scam call. I bought this app to block these, and it doesn’t work.
-- TonyJ#, 2024-11-04

### *---- "Doesn’t block all"
I purchased this app to block all 0843/0845 numbers. It just blocks 1000 (I think).  I contacted them at that is all it does. Every day I get unwanted calls, which ring a couple of times, which I want to stop. I hoped that this app would do it. I suspect that it helps a little
-- Cadan Andrews, 2024-11-02

### ***** "It seems to work"
I was getting several calls a day from 0843 ### #### and 0845 ### ####. They would ring just one ring, or show as missed call, and obviously wanted me to phone back on a premium call number.

Since installing this, I have not had one call.
🤞
-- Christoffe888, 2024-10-29

### ***** "Works for me - brilliant!"
I have been plagued by nuisance calls from Madrid, Spain that really annoy me and after installing this app and adding the city &amp; area code to my list I got none!  Recently they phoned from another area in Madrid so I added the Madrid area code on its own &amp; nothing since! I love this app - it’s really helped my sanity…! Very reasonable price too!
-- Cally Bee, 2024-10-18

### **--- "Doesn’t block as well as hoped"
I get 0843 numbers call me around 3-4 times per day, although this dropped slightly it’s still letting those ranges through - disappointed after paying for it
-- Peter Samuel Harper, 2024-10-12

### *---- "Doesn’t work"
Tried everything your supposed to do. Everything… even what has been suggested. Yet still doesn’t stop 0843 and 0845 numbers. Save your money guys.
-- kingkingdaz, 2024-07-27

### *---- "DOES NOT WORK!"
I still get 0843 numbers calling every day. I asked the app to block them and it doesn’t.
-- ShelleyZed, 2024-07-12

### ****- "Not working as well as before"
Calls that are blocked are getting through and ringing once which is annoying and they are sometimes leaving voicemail messages which is also annoying.
-- Enwezor, 2024-07-11

### *---- "Doesn’t block 0843 numbers"
Doesn’t work won’t block 0843 numbers
-- kx32, 2024-03-23

### ***** "Peace at last"
Having been plagued with around six scam calls every day I seriously considered dumping my number.  All were from an 0843 number which charged £3.20 if accidentally answered, even for one second.  I religiously blocked each number to the extent it was slowing down call answering.

I purchased Number Shield not expecting great results and entered 0843 plus hashes.  Number Shield warned it would take a while to set up the blocking but in reality took less than two minutes to block 10,000 plus numbers.

It has been three weeks and I have not received any scam calls.  It really works and given me peace of mind.  It created a single entry in my blocked callers list identified by reference to Number Shield.  

Wonderful.
-- Brev01, 2024-03-16

### ***-- "Needs updating"
If 0843 ### ### blocks all number beginning with 0843 then why do I still get up to six calls a day from numbers beginning with 0843?
Not helped me. Good luck.
-- 321me321, 2024-02-25

### ***** "Fabulous little app"
Thrilled with this and amazed at how many millions of numbers it’s able to block.  If you’re in the UK, remember to knock the zero off the beginning and add 44 instead.
-- Pz1111, 2023-11-24

### ***** "Number Shield"
Nothing fancy and does exactly what it says. Great app
-- Wizzy2k14, 2023-11-17

### *---- "Not blocking spam messages"
Bought this app to block spam text messages and it does not work 
Not expensive but a complete waste of money.
Does not even put them in the “unknown” folder 
Contacted support a few times, still not working
-- googolmajor, 2023-09-29

### ***** "Worked a treat"
I’m in the UK and was getting up to 6 scam calls a day from a number in London that started with the same 6 numbers, but where the last 4 digits changed each time. Because it was always a slightly different number, the in-built number block was useless. After a bit of research, I found this app. To be honest, I wasn’t sure if it would work, let alone in the UK, but it’s brilliant! I haven’t had a call from them since. It’s really easy to set up and so would highly recommend it to anyone who wants to block a particular range of numbers. Worth every penny 🤩
-- Johno1969, 2023-09-20

### ***** "Great concept and works well"
The app and concept is great. Easy to set up and use.  For those in UK you need to add UK country code and drop 0 from number range.  Took me a while to work this out.  Once you have done this those irritating calls which change the last 3 digits every time you block one just stops.
-- Purrfect Tale, 2023-07-23

### ***** "Works as I wanted it to"
I’ve been receiving calls from a range of numbers that share the same 5 digits, and wanted to block all numbers that have that prefix. 

To do it on the phone, I’d have needed to enter each of the million variations which drove me to see which clever folks have solved the problem. 

You did. Within seconds of installing the app, and by following the wildcard instructions to block ranges, 1 million numbers blocked within a minute.
-- Cleyton1, 2023-05-12

### ***** "Great app for blocking a series of numbers"
This app can block multiple combinations of numbers in one go.
-- Treats111, 2023-03-24
