What is that iPhone Icon? It’s TTY.

Every once in a while I do something to my iPhone that makes a little blue (or grey) phone icon appear in the upper right corner of the screen (Spoiler Alert: it’s the iPhone TTY Icon). Without fail, I forget what I did and need to search forums to find out how to get rid of it. So, this post is to help me figure it out next time I forget…as well as help any of you guys with the same question.

Ok, so here’s the icon that I’m talking about:


The reason the icon is there is that it’s telling me that the TTY function of my phone has been turned on. Enabling TTY is necessary to attach a teletype machine to the phone for the deaf or hard of hearing. You would need a separate TTY cable to use the TTY functionality, and odds are, if you are wondering what the icon is there for, you probably aren’t looking to respond by purchasing a teletype machine…you probably want to know how to turn it off. Here you go…

First, tap the Settings icon on your iPhone. Now, find your Phone settings:


On this screen, you will see the TTY setting that is turned on (at least…it’s turned on if you are seeing that phone icon in the corner).


All you need to do is touch the On/Off toggle so that it’s in the off position. Once you do so, you should see that TTY is off, and the icon will disappear.


And there you have it. Just hit your home button to get back to your home screen. It’s pretty simple, but it took me a lot of searching to figure it out the first time I had the problem.

    its not there!

      Yes, it’s not there most of the time. Some people accidentally activate the TTY function and don’t know how or why it’s there. If your phone doesn’t display the icon, then you shouldn’t have to worry about it.

    TTY for Deaf People, right?

    • Luke November 14, 2010 at 6:51 pm #

      Yes, it is for anyone who have difficulty hearing.

        Took me awhile to find this thread…. I noticed that little icon on my phone, today after I dropped it into my soup…(.I thought it was a signal that I dropped it in liquid…) I proceeded to wipe it off with towels, stupid me turned it on… Ive been pretty desperate all afternoon… it keeps pushing messages…My home button is stuck… and it wont power off… my voice controls keep coming on. How do I fix mend the home button. It is sitting in rice at the moment… hope its not too late… and I’m glad the icon was not a…..you just dropped your phone in water icon and were gonna tell….

        Thanx for the help

          Yeah, as far as I know, Apple has yet to come out with a “you just dropped your phone in your soup” icon 🙂

            My phone seems good…only my home button is still not working, it receives calls, texts, everything… just a bad home button… what can I do???

        • Luke December 12, 2010 at 9:23 pm #

          If you have Apple Care on your phone, or if it’s still under the original warranty, you can check with Apple to see if they will cover the damage to your home button. They aren’t under any obligation to cover it, but they’ve been known to cover accidents, probably just to maintain their good name. Someone I work with has actually had his phone replaced twice because he ran over it with his car…twice. Apple has given him a new phone both times. It’s worth checking.

    3GS- no TTY on the ‘Phone’ screen; how do I get rid of the icon?

  6. ConstantSwagemakers August 13, 2011 at 5:20 pm #

    and don’t tell me to ‘reset’, because everything I’ve got be will gone, too.

  7. LukeCoburn August 16, 2011 at 8:48 am #

    @ConstantSwagemakers I don’t believe that it has anything to do with the model of phone that you’re using because it’s the same operating system. I’m not 100% sure, but I would guess that you’re just overlooking something in the settings…but I can’t be sure without seeing it. Sorry. Hope you figure it out.

  8. ConstantSwagemakers August 17, 2011 at 5:06 pm #

    @LukeCoburn Nothing to do with OS! (of course) The page ‘settings’ in ‘phone’ looks like:

    My Number

    Call Forwarding

    Call Waiting

    Show my caller ID


    T-Mobile Services.

    NO ‘TTY’ switch; NO voicemail password. And that’s it! Now What?

  9. LukeCoburn August 19, 2011 at 4:04 pm #

    @ConstantSwagemakers Sorry…I have no idea. I thought that it had everything to do with the OS. I’m no TTY expert. I just wrote this post to answer one specific question almost 2 years ago. I hope you can find the info that you’re looking for.

    I have read comments from 2010 and its 2016 almost coming to an end I a using iphone 7 and as I updated my software from 10 to 10.1 the TTY icon appeared. Now I don’t have the TTY button in Settings > Phone. Resetting the phone is an easy option but again a lot of effort to get all the applications etc etc back. Checked several blogs and sites, but still not found any solid one stopshop fix for this problem…
