It may have sometimes happened to you that your iPhone may have a problem reconnecting to a cellphone tower. In such cases, you would normally see a message that reads “Searching” that never really goes away even when you are actually close enough to a cell phone tower. In such cases, the only recourse that many resort to is to reboot the iPhone. While this trick works, it is often laborious since you have to go through the entire ordeal of rebooting that takes at least a few few minutes.
Do you have an alternative? Yes. Next time your iPhone is stuck on a “Searching” mode, simply go to Settings and turn on the Airplane mode. Once done, you may swipe off the airplane mode and shall notice that the iPhone will now be able to connect to the cellphone tower.[via LifeHacker]
