  How can I prevent SMS messages from being shown on the iPhone lock screen?  




I am aware that the text message preview can be disabled so that the actual message is not displayed. However, there is still an alert that a text has been received and from whom that can be openly seen on the lock screen. Therefore full privacy is compromised.

Can I disable this alert completely on the iPhone 4?

Thank you
Go to Settings. Then Notifications. Then Messages from the list. There you'll see several options. One of them being "View in Lock Screen." Set that to "off."
