Why iPhone 4 restarting??

When I have connected my iPhone to the PC to update, it is just saying that there is no SIM card in the phone. It is really annoying. What is to be done? Can I restart the phone? I will be thankful for your help to get out of this problem.

Hi Homer,

Is it doing the same thing when you insert another sim card? You can try to turn off your iPhone, take out the sim card then turn it back on again and try again. Try to also reset the toggle of the airplane mode option on and off. If it is still not working, try the steps below:

·         Turn off the iPhone’s WIFI

·         Turn off the phone itself

·         Removed and wait for 1 minute before you reinsert the sim card

·         Turn on your iPhone.

·         Turn on your wifi afterwards.

This is a known issue when updating the OS of iPhone.

First, make sure you are using the latest iTunes when updating your iPhone. Download the latest iTunes and install it. Once installed, connect your iPhone to your computer using the USB cable that came with it then start iTunes. In iTunes, click your iPhone then try updating again. See if this works.

If this doesn’t work, another way of updating your phone is to do a factory reset. This will allow you to update your iPhone to the latest iOS. When you reset an iOS device, you are restoring its settings back to factory defaults.

In Android, when you factory reset a device, it will restore the device to its default factory settings or the original settings that came with the device when you first bought it.

In iOS, factory reset works a little different because instead of restoring the original firmware or operating system and settings that was built-in to the device, it will install the latest operating system or iOS after erasing all the information and settings. Once you have the latest iTunes installed, backup your device to iCloud.

To do this, on your iPhone, go to “Settings”, select your name, “iCloud” then “iCloud Backup” and then make sure iCloud Backup is turned on or enabled. Next, tap “Back Up Now” then wait until the process is complete. When it is finished, go to “Settings”, select your name, “iCloud” then turn off “Find My iPhone”.

After this, on your computer, start iTunes then connect your iPhone to your computer using the USB cable. Select your iPhone when it appears in iTunes. On the left pane under “Settings”, select “Summary” then click “Restore iPhone” on the right. Click “Restore” to confirm. After this, iTunes will erase your device and install the latest iOS. Your iPhone should restart automatically once it is complete.
