Hi there... recently this error message appear many times each day & specially when am outside my home!

And I just finished searching for a solution.. and finally - و الحمد لله - I found it.

This error message appear because you configure your iphone for a specific wireless access point (AP(. So when your iPhone out of reach that AP, it will try to connect but not find it; that because this error message appear.

Solution: Switch Off your Wi-Fi. or if you don't want to, then switch on the feature [Ask to Join Networks]

Note: I Guess Any One Have a Data Service with his Mobile (Cellular) Line, Will Not Face this Issue ;-)
