Is it necessary to turn on icloud?

Need to be turned on. In addition to helping us save data and save storage space, iCloud can also quickly help us migrate information on our mobile phones. There is a "Find My iPhone" function in iCloud, which is a new feature added to the iOS7 system. It has anti-theft and anti-loss functions. We can remotely locate the current location of the iPhone and send it some special operation commands, such as locking or erasing data.

When this feature is turned on, if the phone is stolen and someone else wants to forcibly flash it, they will be prompted to use our Apple ID account to activate it. If we can't unlock our account number and password, it's just a piece of scrap metal.

The functions iCloud provides us are very useful, whether it is for the data on our mobile phones or the anti-theft and loss prevention functions, they are very considerate. iCloud can protect our mobile phones in all aspects. I personally recommend that everyone turn on this service.
