Hi there and welcome
Can you tell me what you did please to lose the notes? Did you delete them?
Where they notes stored locally on the iPhone or via an email service like Gmail?
Did you ever back up the phone via itunes on your computer?
ok, then you will not be able to get it from the back up there.
Can you hold the home and power buttons on the iPhone for about 10 seconds until you see the apple logo, then release.
Let the phone restart and tell me if the notes are still missing please.
ok, but the instructions you do on the phone, not on the computer
Ok, go to www.icloud.com
Sign in with your Apple ID and tell me if you see it there please
on the link I gave please
check if you see the notes there please
ok, then you do not have it on the cloud
The notes are lost from this phone sorry, this was the last option we had
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the page, then submit, that would be greatly appreciated.
