How do I block unwanted calls on my Nokia Windows Phone?

Nokia SMS Call Filter

There will be a time in life when you need to block someone, be it a cold sales contact or someone who may be harassing you. Unfortunately, Windows Phone 8 doesn't currently have a built-in blocking feature to prevent numbers from sending messages to your smartphone, nor can the operating system halt calls in their tracks. But Microsoft did make tools for manufacturers to enable this feature, should they want to make it for their customers.

This is where Nokia came in with its 'call + SMS filter', which launched on Windows Phone 8 last year for Lumia devices (Samsung has it in their ATIV line of Windows Phones too).

We'll quickly walk you through how to set everything up, just in case you've yet to fire up the filter settings area for the first time.

The filter is not enabled by default, so you'll need to turn it on. Luckily, everything can be found under your phone's Settings.

call + SMS filter (for Nokia Lumia phones only)

  1. Swipe right to the app list
  2. Scroll down until you find 'Settings' (tap)
  3. System
  4. Scroll down until you find 'call+SMS filter' down the list, then tap to open

If you haven't accessed the feature yet, you'll have to accept the terms of use and privacy policy, which will be displayed with an option to accept or cancel. Hint: if you wish to use the filtering system, hit accept.

Call SMS Block

To add contacts to the block list

  1. Head into phone history (Phone) or messaging (Messaging)
  2. Long press on a contact or message
  3. On the pop-up dialog, select 'block number...'

Call SMS Filter

Back to the filter settings area. Selecting 'advanced' will open up some handy options to configure the blocking of withheld numbers automatically, enable/disable the Live Tile and toggle toast notifications. It's all simple stuff. Pinning the Live Tile to your Start screen is a convenient way to monitor what's being blocked, as well as providing quick access to the settings area.

Advanced settings for call/message filtering

  1. Settings
  2. System
  3. call+SMS filter
  4. advanced
  5. Enable/disable 'Block withheld numbers'
  6. Enable/disable 'App Live Tile'
  7. Enable/disable 'Notification'

Call SMS Block


Unfortunately, there doesn't seem to be a way to pre-block someone through your People hub (aka contacts), so you'll have to wait until they call or message you first before filtering.

Are you utilizing this feature on your Lumia Windows Phone?

Love this feature! Too bad we can't block Private or Unknown callers!

ahmedjan87 says:

These are what you would call withheld numbers

Win1859 says:

Does it block the call entirely or send it straight to voicemail? It would be nice to have the option.

NO not withheld or not private...How do you block text messages from a number who has never sent you a text before and who's number you did not previously know?

Ryan Crowley says:

I just bought a nokia lumina 520 from walmart for $48 that has that feature.

GrayW0lf says:

As ahmedjan87 says, you have to go into the Call + SMS Filter settings app, click "Advanced Settings" and the enable "Block withheld numbers".

JaiMento says:

You can block Private numbers. There's a toggle in the advanced options to auto block calls from withheld numbers.

NIST says:

I'd like to block Rodney's mom. The 3am booty calls are getting ridiculous.

rodneyej says:

Lol❕❕❕.... You burned me... But, you'll pay.. You'll pay big❕

Never a dull moment with you two!

rodneyej says:

We just can't wait till next Wednesday.....

Groover1971 says:

Everytime is see a message posted from Android, it makes me cringe.

Toink says:

The in ablility to 'manually' add a number in this app is really frustrating.

Actually, the LACK of decent Call/SMS blocker apps in Windows Phone is even more frustrating!

rodneyej says:

True... You mean like how you could in WinMo?❔❔...... See what I did there....

Toink says:


Like I could with My Nokia N9 using the most effective Call/SMS Blocker App, that is Firewall+Pro.

rodneyej says:

What do you mean no?

TKETZ196 says:

I remember all the various call block apps available on windows mobile. I had them on my device and it was fantastic. The fact I can enable it to only allow my saved contacts to call.and text me was great and sorely missed. There were many things that WinMo had that WinPhone didn't. I almost jumped ship to Android but I hate Google more. I do miss at times the flexibility and customization that WinMo had in a familiar environment, akin to the desktop. I still stick to Windows for the unmatched compatibility to the desktop Windows 8.

rodneyej says:

So true... MS should go back and dissect WinMo.. Lol!❕... It was the best POS OS around... Lol!❕

sharathu7 says:

U can actually do it... By calling the number and end the call before it rings... Then go to call history and block the number... Same with contacts in people hub...

Clancy Weeks says:

Actually, you *can* manually add numbers. Just dial the number once, then hang up before it begins ringing so it is on your call list. Then you just press and hold the number to bring up the menu where you can select Block Number.

Works for me.

blackjackrm7 says:

Hey guys totally out of topic but does any one know an app which lets me see what app uses how much ram ? Thank you

ahmedjan87 says:

No that's impossible

rodneyej says:

I guess nobody thought my joke was funny.... :'(

Sameer Beri says:

Dude search in google to know ram of your device :D

rodneyej says:

That's not what he's asking... He wants to see a break down of each specific apps usage... Android has a cool feature like this.. Just like on a PC Android lets you view system performance, and resource usage in real time..
A lot more people would take WP more seriously if MS would add some cool PC like features to the OS... Maybe that's MS next thing to work on... Things that make the OS itself fun.. This is somthing Android is really good at...

theefman says:

Can't remember the last time I looked at the resource usage on my PC and thought, what fun...

rodneyej says:

That's you.. I bet your GF, or wife, wouldn't consider the WPC app fun either..... People are different, and a lot of people think this feature is cool in Android.. Are they dumb?

NightWatch71 says:

Why would you need that though? OS itself handles it just fine. This is a solution to a non existent problem.

rodneyej says:

See, people like you just don't understand... Maybe you wouldn't like to see your OS working away, but some dudes just think stuff like that is cool to monitor... The overlay on my HTC one X can be shown on top of any screen.. Developers love this stuff, and some more tech minded WP fans, like myself, would like to use it to..
You can question why certain people want, and like, certain features all day long, but the fact is that WP needs to adapt to more than just one kind of user... That's what the platform is SUPPOSED to be all about, not just some cookie cutter iOS way of doing things... This would be a awesome feature, and MS better start thinking this way to pull in more customers...
Cortana is a start, and the avatars in the XBH are exactly what I'm talking about... But, WP needs more, much more of this type of thing........ IMO❕

blackjackrm7 says:

Yeah man..hey rodney are u on Xbox live?add me plzz...Ritabancr7mitra

rodneyej says:

I don't play much games, but I'll see if I can add you.. Thanks!❕❕

If I'm not mistaken, didn't Windows Mobile 6.x phones have something similar to this that allowed you to see what's running? I remember something like that on all my old WinMo phones......

rodneyej says:

Lol❕... We were just talking above⬆ about how we sometimes, kinda, in a way lol,, miss WinMo.. It had "stuff".. Useful stuff... I should go to User Voice and make a request for MS to CAREFULLY make WP more like WinMo!! ... It's kind funny.. Lol❕

Now your making me want to find my old Samsung Jack or find an HTC HD2 that hasn't been polluted with lagdroid. The most technical WinMo phone I had was the LG Incite which was a pile of crap with it's unresponsive screen & keyboard that took up 3/4 of the screen in landscape mode.

rodneyej says:

Wow, yours had landscape mode?

Xaphoon148 says:

Yes, had that on my HTC touch diamond II. It was indeed very useful to find out why the h... that POS didn't respond when pressing some imaginary buttons on the screen....
Luckily I couldn't care less for it now, as my beautiful yellow Lumia 1020 just works and responds even before I touch the screen :P

Well you could do a work around. Most system information apps show ram usage.

-open that system info app and take down available ram
-now open the app you want to know, then open that system information app again
-subtract the difference

rodneyej says:

That could work.. Not sure how accurate that would be.... See, this is why MS needs to open up the OS to developers more... I think with WP8.1-0xxxx developers will be able to do much more... If so this definitely will boost the amount of useful apps in the store.

Ankmeyester says:

The wait for BUILD is excruciatingly long and filled with how-to posts :|

rodneyej says:

Just 9 more days... You can do it❕

rysliv says:

Why does it always have to be Nokia exclusive. Give some love to Ativ and 8x/s/t users for once.

Conhavi says:

Ativ S can also do this

GrayW0lf says:

Because Nokia wrote the app for their phones. The article also says that Samsung has provided similar functionality for the ATIV series of phones as well. HTC would need to do the same for the 8X.

Toink says:

Doesn't the Ativ got this feature BEFORE Nokia came out with this app?

Conhavi says:

Yeah, that's true

rodneyej says:

It's Nokia's apps❕... You should go complain to Samsung, and HTC..... Or, a better option would be to get a Lumia device and be done with it.

cyborg4 says:

Nokia does work on their WP8 phones unlike those other OEMs.

MacDaMachine says:

Nokia Phone Central ;)

rodneyej says:

Pretty much..... That's who supports the platform... Those who step forward get attention.. Now, I hope that changes, but until others start to take WP seriously then Nokia central is ok with me....

zaidgkhan says:

Mine says "Something went wrong.. Can't open the filter at the moment. Please try again later or restart your phone" what to do now? Any suggestions.

zaidgkhan says:

How do i reinstall??

Toink says:

Ever heard of centido comun?

There you go....

NightWatch71 says:

You know you could've just said common sense :)

zaidgkhan says:

How do i reinstall... -_-

Devin19 says:

I'd try again later, or restart my phone if it still doesn't work later...

LqDFx says:

I've been using this for a week or so. Unfortunately I've found that it blocks the calls, but still lets a voice mail be left. I've picked up my phone to see I have a voice mail, but no missed calls. Seems it silences the call and that's about it.

rodneyej says:

I was wondering about that... I think I've seen it behave this way before..

GrayW0lf says:

That's expected behavior. You aren't stopping the calls at the carrier. Only at the phone. The only way to prevent the voicemail is to answer a call if the carrier is not providing the blocking functionality.

rodneyej says:

True, and this is especially the case with visual voicemail.

Being using since it came out and all those telemarketing are block or sometimes random calls which is a scam and some people that talk sp much crack I block

I did this once on my 920 because of some spam text I received. I showed my best friend how to use it too, since she had some telemarketer calling her on her 521.

Darren Walsh says:

You don't have to wait for them to call you, you can just ring them and hang up straight away, then they'll be in your call history

cdodgela says:

If you know the number you want to block, call it and hang up immediately. You can then block it. Doesn't matter if it is incoming or outgoing..

ricardios says:

HTC where are you with this feature? Will 8.1 have this built in?

strikeswp says:

^This guy knows what I'm talking about. We are the step children of WP8.

strikeswp says:

I have it now ^^

gjdj93 says:

Just like I did today... People at work calling my personal phone... Blocked.

lippidp says:

Hahahaha! Yeah, fuckem....

topleya says:

I've got a massive list of numbers blocked on mine. Most of them are EE & T-Mobile UK trying to upgrade me, even though I'm within contract with them.

They even called me the day after I renewed to EE to offer me an upgrade.

The others are PPI and injury claim companies.

TechFreak1 says:

The problem is you can't block em all... Lol (I've tried). It is incredibly annoying when they call persistently, i had a company call me no less than 5 times during a presentation to upgrade my contract the day after I asked for my pac code from o2. I had to excuse myself and go out of the room as i thought it friend or family member trying to get hold of me urgently lol. Literally tore the call center's cr's line managers ear off after the meeting and have had no marketing calls since.

This is the BEST feature in my phone! I feel powerful when I block numbers!

Munkeyphyst says:

You can call a number, hang up immediately, and that number will appear on your call history list to be blocked

TechFreak1 says:

Not very practical :P.

Munkeyphyst says:

Sarcasm? If you hang up immediately, before it even rings, the number called doesn't receive notice of the call. It isn't elegant or intuitive, but it does function and effectively serves the purpose, so in that sense it is "practical"

CJ Thunder says:

Sorta similar is there a way to stop a call from ringing, continue to use my phone, but not ignore the call so it doesn't go straight to vm?

lippidp says:

Use the silent ringtone for them (if I understand your question).

CJ Thunder says:

No. A call takes up the screen. I don't mind getting a voicemail, sometimes I just don't want to talk to someone and don't want them to know I ignored them.

firewolf006 says:

What do you mean? Either way its gonna go to voice mail.

Amran Nagal says:

Wp Central is seriously running out of stuff to post lol.
April 2nd Come soon...

firewolf006 says:

That's funny, I just used this feature right before this article was posted. Someone's spoofing my own number to call me. People need to grow up >:(

strikeswp says:

It's unfortunate that this is not just a basic OS feature. My HTC 8XT does not have this. Total trash.

peachy001 says:

Anyone have any idea what the person on the other end hears? Does it ring (and the phone just does not display it) or does it send straight to voicemail? Could do with the option to send an automatic message back saying blocked.

rodneyej says:

Sends straight to voicemail.. It has to..

dalydose says:

Is this verified? Because, that would be perfect. I send my voicemail to YouMail and then use Ditch Caller to play "out of service" to telemarketers.

peachy001 says:

Not heard of that before.

danielm298 says:

I use this feature every day..love it

ashram says:

so, what does the blocked person that is calling hear? does it continue to ring? go to voicemail? fake "disconnect" message?


nevermind... answered 3 posts up !


I use this all the time and it works a treat as it get a lot of marketing calls, one downside is that it does block legitamate calls from companies.

TechFreak1 says:

You can block texts as well, the withheld call block feature is neat but useless to me without a whitelist - as all out bound calls are withheld at work.

TechFreak1 says:

If it had a black list / block list, white list and customisable filtering rules it would be brilliant.
It does need a whitelist as it currently blocks all withheld numbers for example sms alerts from your bank may have a withheld number (Santander does) and it blocks it.. If you miss the prompt (tile not pinned) its gone unless you dive into the settings. The action center will really help, can't wait for wp 8.1!

AskaLangly says:

Did not work for me, so I had to subscribe to Verizon's FamilyBase JUST to block numbers. But I also have the ability to block private and unlisted numbers, so an additional fiver wouldn't hurt.

cuwe says:

But how's iPhone 'Do not disturb' mode works actually ? I called my friend and it sent me straight to voicemail box .

myrandex says:

Another limitation...no way to backup the blocked list. I had a nice collection of student f'ing spam calls that the do it all organization apparently can't get off their @$$ and shut down, so I would have liked to migrate those to my Lumia 1520 but alas that's not an option.

siddhant_96 says:

Why wait for the other person to call. Just call him and quickly end the call and there you go!

I used it a few time, once used it to block my Ex GF. But anyways HTC users can get this app by using the infamous proxy method.
1: Download an app called SysAppPusher/Lumia Pusher.
2: Open the app swipe left twice then you will see 'My App' option, now select add app, then search for call+SMS Filter. Tap it then select add it to my apps.
3: Open WiFi, tap and hold the connection you are using, tap edit.
4: You'll see a proxy option, here type this into the first box, then type 8888 into port. Now tap ✔ and exit.
5: Now open SysAppPusher, swipe to My apps section, tap on call+SMS Filter and wait until it open the page and show you the option to install (It may take a few tries).
6: Now tap on Windows Button, and go to WiFi and turn off proxy, then go to multi tasking menu and open the call+SMS Filter page.
7: Now hit install and enjoy.

Either that or change your phone. Or even better, 'deal with it' :3

svknet says:

My Samsung feature phone has better call blocking ability. I can enter phone number manually even if I dont receive call from that number. I can also block entire series of phone numbers (e.g. block all calls starting with +919145 which is used by telemarketers).

Windows Phone Call + SMS blocker has long way to cover before it becomes perfect app for purpose. I still love my Lumia 620 :)

Problem is it doesn't block pic messages. Only text

ratsttam says:

This makes me wish that carriers other than Sprint offered Google Voice integration. Effectively blocking the calls/texts at the source. Even better was that if enough people flagged a number, it would block it as spam much like e-mail would be. I would look at my logs and see a bunch of calls from numbers that I've never seen before. I miss that a lot. 

It's still nice to be able to block calls. Easy enough to just nuke the visual voicemail that's left. Sure beats being interrupted.

Works well for calls, but even pressing the unblock button on texts that are auto blocked does not stop them being blocked next time, nor doses adding that number to your phonebook

jay6600 says:

i love this feature 

was getting plagued by PPI type insurance claim calls several times a day ,these people just wont give up they constantly switching and using new numbers but as soon as i get one they get added to the blocked list,just wish that i could export the list for after reset or upgrade phone ,currently have to keep a hard copy and if reset i have initiate a call & end / add to blocked to set the list back up.


Still lets MMS through :(

Debora Bell says:

Hello ! Is there something similar for windows phone 7.8 ? Because I have a lumia 610 and a withheld number can stop harassing me and I don't know how to blockt it :(

Steve Martyn says:

Hi Debora, I too have a 610 on Windows 7.8 and after looking for days unfortunately due to the architecture of the phone it is technically not possible to block any calls or messages. The are no Apps available and Microsoft with not be supplying any future update. Looks like were been bullied into an upgrade. Hope this helps. Steve

Portia Mbewe says:

my call and calls and sms filtr doesnt wanna work it says something went wrong how do i make it work?

Peggy Allen says:

How do the people calling or texting know that they are blocked?  I can still get the calls and text. They just go to my blocked calls=SMS filter.  I don't want their texts or calls to go through to my phone.  Is there something I'm missing.

HN2014 says:

Definitely need to be able to add blocked numbers before they call or send sms!!! A MUST!! Tks

21stNow says:

I have a Lumia 925 that shows that the software is up-to-date.  However, I don't see the call+SMS filter in my Settings menu.  Am I missing something here?

i have lumia 520 i cannot find it [lz help me regarding this


When I try to access the feature, it says "Something Went Wrong" "Cant open the filter at the moment. Please try again later or restart your phone" Is anybody else having this problemor does anybody know to fix this issue so that I can use the filter?
