If wifi is available, you can boost your connectivity that way. If 3G is not available, turn it off. Turn-off all apps and manually restart the phone.

We have found that the iPhone 4 doesn't have as good signal as the iPhone 3G.<br />
<br />
There is of course the problem with the aerial on the phone being shorted, especially by left handers (holding in left hand shorts out the aerials), so it can be improved by using a sleeve of other case that can be kept on when the phone is used.<br />

Hello:<br />
<br />
Compare to my previous LG cell phone, it seems that my iPhone 4 doesn't have a strong receiving signal ability.<br />
<br />
My old cell phone is working well in every room, but now my iPhone is only in one room.<br />
Sometimes it shows &quot;No Service&quot;.<br />
<br />
The carrier is AT&amp;T. <br />
<br />
Thank you.

The iPhone is a smartphone made by Apple Inc. It and the iPad, along with several other mobile devices from Apple, run on the iOS operating system, which has its own topic, as does the iPad for device-specific questions. Native iOS applications are written in Objective-C or in Swift using the Cocoa Touch frameworks or HTML5 compiled with the help of a package manager such as Adobe PhoneGap; a common IDE is Xcode.
