    I have been having an issue with my earlier 4S and even with the replacement given to me.

    Whenever I get back into an area with decent coverage it will still show as 'No Service'. Only when I try and dial 'a/any' number, the network will come back!

    Any ideas?

    I have the same deal time to time. I just put airplane mode on and off :/

    How long are you waiting after you reenter a coverage area? Once the phone (any cell phone) determines that there is no network available it will only search for one periodically. This is done to preserve battery life, since a phone which is actively searching for a network drains power MUCH faster than one with an active connection.
