My iPhone keeps saying "searching" at the top left corner

try a rebooting your phone. hold the home button and power button together for 10 to 15 seconds or until you see the apple logo and then release.

I am restoring my iphone twice a day because it keeps searching for network. Besides the modem firmware (2.0.10) disappears from the Settings>General>about. When the iphone starts searching for network there is no modem firmware number (version). APPLE DO SOMETHING ABOUT IT. It is annoying besides we may be loosing a lot of money. I bought an expensive iphone to be able to at least make phone calls. This basic thing isn't possible with iphone 4S. So please resolve the problem.

This is happening to me on iphone 5 iOS 6.1.3... This MUST be a known issue with the phone by now when I see how many this affects... WHY is it still a problem with iphones???? I demand a fix!

i have the same Searching problem oh my iphone 5 with 6.1.4

but the difference is it looses network when the battery drains and device shuts down.

i turn it on, but it keeps saying Searching.. even when the sim card is not inside.

have any of you had this battery-related network issue?

(will never buy an i phone again)

Yes i did! said searching and i thought it may have been my sim but my sim was working fine when i put it in another phone! Now my phone has jst completely blanked out and ONLY the apple icon will show up when i plugg it into the charger- thats all! stays on that screen, even two hours later!!!!!! i have a iphone 4 btw... hmmm something apple needs to look at! its happening to ALL iphones by the looks of it...
