  • This is tongue-in-cheek, right?  Who doesn't know what their phone number is?
  • I have 4 lines and travel. I don't know half my numbers.
  • I have tried all 3 methods and none of them show my number, is it my 925 or sim card that's the issue?
  • Just checked my 830, also nothing. Maybe because it's an off-contract phone with a pre-pay SIM card
  • Same thing to me also...
  • Worked on my 1520, but not on my 640xl, both running windows 10
  • It looks like these screenshots are from Windows 10 mobile. If you're on Windows 8.1 then it might be different. You can always call another cellphone and see what number appears.
  • finally - the best solution!
  • And save it in your contact list ;-)
  • This!
  • My 950XL too.
  • It's your card. Depends on the SIM and the carrier.
  • Its useful if Intune (and other MDM solutions) can read this field. Currently this is not showing up on Intune Lumias.
  • I'm literally using a line right now that I have no idea what the number is. I have to keep looking when people ask because it's simply not in my memory yet.
  • I just don't understand that.  I just don't.
  • It's not surprising. You're not very bright so you must not understand much.
  • When I travel, I type my number in large fonts, take screenshot, crop, and make it my photos tile icon.
  • Those who just got a new sim and is still trying to remember their new number if they chose against keeping their existing number for example
  • Most of us do yes, but when we buy a new SIM card(esp when we travel) we tend to forget the number or lose the paper which had it printed. 
  • people that just got a new one for their work
  • Someone that was just issued a phone from their company, someone that just changed their number, someone that grabbed a friends phone for the night and needs to be reached while the friend is passed out drunk. There are many reasons why you may not know the cell number. Haven't you sold your Windows stuff yet so you can leave this site and stop with the poor comments?
  • Seriously, I know a lot of middle aged to old people ho can't remember their phone number. Also, as commented above, if someone just got a new free SIM, where I live it happens a lot just for the sake of promotion, it is really difficult to remember that number for a few days. So, I must say this information was definitely helpful. Posted via my Samsung Galaxy S3 Neo which isn't as much abandoned as any Windows Phone on the Windows Central App for Android
  • you'll be surprised. it takes me MONTHS to remember a phone number, thus, I have help on to my cell # for well over a decade now.
  • When I got my second line last year, it only took me a day to commit it to memory.
  • i have my nember for about 7 years now , but still can't remember it :\
  • 2 and a half here lol
  • Method 4; Call yourself! LOL!
  • If you don't know what your number is then how would you call yourself?! (-_-) And even if you call yourself from your phone, what would you achieve? A busy tone!
  • This! Posted via my Samsung Galaxy S3 Neo which isn't as much abandoned as any Windows Phone on the Windows Central App for Android
  • Lol you call from the phone that has the number, you vant remember ☺
  • i would assume he meant calling himself to his house phone from his cell phone, ppl still have those i still do.
  • You mean landline? It would work only if the phone has caller ID. And a person should express his clear views in the statements he makes. Others won't keep guessing what it actually means. The most clear meaning of his statement is what this thread is all about.
  • No, method 4: Ask your SO.
  • Actually it should be calling by your unknown number to an another number to get your number.
  • Yes. The most common and effective way.
  • Never go full retard.
  • Put an entry with your phone number into the Contacts app. Also, put it into your email signature.
  • That's what I do (phone number in contact). None of the three options mentioned in this article does show my phone number.
  • Same here. Neither option works for me. Lumia 920 - México - Telcel
  • Not able to find NL1520 :'(
  • In The Netherlands you can dial *#06# from any operator. I think it 06 because all mobile numbers start with 06, regardless of operator.
  • *#06# doesn't give you your phone number.... This is a universal code for getting the IMEI of any phone.
  • Same here, 2degrees NZ. Maybe it doesn't work where number portability exists?
  • Or where you retrieve a number after losing it with a stolen phone or phone accidentally flushed down the toilet.
  • Same here (Vodafone/NL).
  • same here: Vodafone - Germany
  • @Neil Katz, wouldn't recommend putting your mobile number in your email signature unless you specifically use that phone for work :) or have dual Sims.
  • King of clickbait articles confirmed...
  • You don't even understand what the word 'clickbait' means. Clickbait is when you ask a crazy question that is not likely true e.g. 'Does Windows Phone cause cancer more than the iPhone?" or 'These 5 Windows Phone tips will make you super attractive'. Basically it is posting something with no real knowledge or conclusion. This article is a simple how-to for new users. You find it silly, but so what? People throw around terms without even knowing what they are talking about to sound smart and critical failing on both accounts.
  • Lol
  • Oh what a day, what a terrible day for poor Bojan Malinovicnicov...! :-D Posted via my Samsung Galaxy S3 Neo which isn't as much abandoned as any Windows Phone on the Windows Central App for Android
  • Agree with Daniel.
  • I always thought clickbait was more about coming up with titles that can provoke the reader's curiosity or interest and intrigue him into clicking the title and seeing an article that has little to nothing to do with the title.  
  • I do know my phone number but I tried your method on this article to find my phone number for curiosity. Because someday I might need this in the future when I travel. But I can't find my phone number from those tips you just provided. Am I doing something wrong? I'm using Lumia 950 w10m .29 build
  • Oh yeah I found the place where my phone number should be. going to phone app, click settings and then click more settings and I see there is a place where it says"my phone number" I have that as null because my number is secret so it won't show the number. Maybe.
  • This would be the worst clickbait, ever. What is sensationist that makes you just HAVE to click?
  • my ****
  • Well my number is the SIM linked phone number and not the one I actually use this SIM for after Moving my number over 
  • This will only work if the number is stored in the SIM. Not all operators store the number in the SIM though.
  • Ahaa, thats why im getting nothing. Thnx.
  • It's not showing in my Lumia 1520 ( build 10586.63 ) - I tried all the above methods mentioned 
  • not showing for me either, tried all 4 of them on my lumia 730
  • Uh, mine isnt listed under any of these. Is there a way to manually add it?
  • You would have to find a phone (probably a basic feature phone) that supports editing "my number" area of the sim card.
  • I think this feature in Windows 10 Mobile only. May be you have a Windows Phone 8 device. I am not sure, but may be that's the reason Posted via my Samsung Galaxy S3 Neo which isn't as much abandoned as any Windows Phone on the Windows Central App for Android
  • I'm using Lumia 950 w10m .29 build and can't find my phone number with these 4 tips provided on this article
  • Oh yeah I found the place where my phone number should be. going to phone app, click settings and then click more settings and I see there is a place where it says"my phone number" I have that as null because my number is secret so it won't show the number. Maybe.
  • Same here unfortunately, though I'm pretty sure that'​s the SIM card's fault.
  • There's a widely reported bug concerning the wrong number showing up in the phone and there being no way to change it. I've owned 4 different Lumia handsets and my phone has never shown the correct number.
  • Still waiting for windows 10m
  • Hmm, if you have a dual sim phone, call your second sim with your first sim :p then you'd see the number lol
  • Method 0. Go to phone dialer and go to settings there, then touch more settings. Done.
  • Still not there on my 950XL.
  • I tried all the three methods but none is showing my phone number. The first method shows a text "Your phone number is" and then nothing.
  • None worked for me.
  • Really? Just be a slow news day.
  • Really? We immediately posted two stories after this.
  • " 'Cause I can be a boss wherever I am now"... Says Daniel Rubino. ;-) Posted via my Samsung Galaxy S3 Neo which isn't as much abandoned as any Windows Phone on the Windows Central App for Android
  • MS's Call blocker
  • Method 4: Can't you just ask cortana?
  • Do these features work on devices registered with Windows Insider? Because in India none of these features work (at least not on my phone); Place for phone number in Phone setting is vacant, MDN in About and Phone number in SIM setting are totally absent. Are these features only available on new W10 phones only?
  • I dont know. I am on 640XL latest W10 build. None of the above works. May be only for US carriers.
  • OK, I have to admit, that was something I re
