non-iOS users can't contact my number after switching to Android

But after all this, my friends using iOS still can't send me text messages and their texts to me still show up as iMessages on their iOS device.

IF your friends are attempting to text you using imessage on your non iphone device they will then BE UNABLE to text you as you have de-activated your imessaging login. When people using Apple devices want to text you they will then do what everyone else does and that is use regular celular data text options to text you. It's my guess they are continuing to try to text you using the imessaging feature which is exclusive only to iPhone users. Hope this helps!

I am having the same issue - I switched from an iPhone to Samsung Note 3.
I can message "to" iPhone users but when they reply I do not get that response - I have unregistered my iPhone and I turned off SMS on that device.

I followed the instructions here:

no joy...
This is frustrating.😟

if you still have your old iphone

Settings > Messages > Send/Receive > and tap your Apple ID, then tap Sign Out.

Also go into the settins for phone and change your number to 000-000-0000

Worked for me!

This is the option that worked for me after trying all of the other fixes to no avail. I also found this support tip from a Verizon wireless tech at almost the same time I found your post:

Did you previously have an iPhone before activating your new S4? There have been several reports of people who previously had an iPhone but change to an S3 and are no longer able to receive SMS from other iPhone users who have iMessage turned on. This may also be the case with the S4.

You need to go to https://supportprofile.apple.com/MySupportProfile.do and unregister your old iPhone to resolve the issue. Once unregistered it may take a few hours before it updates and you're able to send/receive text message with iPhone devices that have iMessages turned on.

My texts started coming through about 30 minutes after I unregistered the previous iPhone I had. That was the most frustrating experience I've had with Apple although there have been other issues with them too. I probably will never ever go back to Apple again.

They need to send as SMS and if you still are signed into your iMessage account, you should sign out.

So here is what I was told from Apple support as of 4-16-2014. Apparently they are aware of an issue with Iphone users that cannot send text messages to non-iphone users who once had an iphone. All the reccomendations on here are correct in that you have de-register your number in order for iMessage to be deactivated. You make the necessary changes to the old iphone if accessible. However, if you have made all those changes, I was informed that Apple is aware non-iphone users cant recieve texts from current some iphone users, despite the reccomendations. Therefore, the issue is on their end and I was told that an update fixing the issue is required. I asked if there was a projected timeline but they said they did not have one. Essentially you are screwed after leaving Apple despite having made the changes they reccomended. The only option at this point is wait for the update or change your number (is my guess). This is because after the 24 hour period has passed in which the number will take to be deregistered, there is nothing else available to do in order to fix. The alternative is letting everyone know that has an iphone and is a contact of yours, to turn off iMessage all together. Shame on Apple for not addressing the issue quickly. The representative told me they are aware of the problem and will put out an update whenever that may be. I think this sways me to never going back to Apple because it has been such a hassle when I switched.

If turning off iMessage on the device, contact apple support through the link provided.

They will manually revoke your certificate.

After trying some of the online fixes, the only solution was to contact Apple Support to "de-register" the phone number from Apple. They will not charge any support fee as it is a known Apple issue. Apple support person was very helpful and problem was fixed within a few minutes.
