How to get rid of “I'm mobile” status when not actually logging in?

Question

I often see my cousin status to be "I'm mobile" but when chatting with him, he recieves no message from me. He doesn't know how to turn that feature off. Please guide us how to.

Answer 1

That's because he has registered his phone to use Y! Messenger via texts. And the status appears because he has set Messenger to sign in automatically to the phone when he signs out from the desktop Messenger.

Look in the Preferences to turn that off.

Also, when you send a message, he should receive a text. Try updating the phone number in the settings to use the feature.

Answer 2

I think , he has registered his mobile number in Yahoo messenger.

To remove or change your status, do the following:

1. Sign into Yahoo! Messenger from your device.
2. Choose Preferences.

3. Choose Mobile Status Message.

4. Provide a new status message. Note: If you do not provide a new status message, your status will continue to show as "I'm mobile."
5. Choose Submit.
