If for some reason your IPhone has stopped responding to requests and somehow responds to the actions being performed, that is, it "hangs", then you need to restart it.
Instructions
Step 1
However, wait a couple of minutes before proceeding with the reboot procedure (the phone may be restored to work). If you were using an application while the phone is frozen, try closing it. To do this, press the Home button.
Step 2
In the event that the first method did not help you, hold down two keys on the IPhone at the same time: Sleep / Wake and Home. Keep them until the screen turns off. To have the phone turn on automatically, keep pressing the buttons. However, if you take your fingers off the screen after rebooting, you will have to use the Sleep / Wake button again. These actions also exhaust the procedure for rebooting the IPhone.
Step 3
It is worth noting that some phone owners try to reboot their devices if they stop seeing the SIM card. Sometimes it really helps, however, in most cases, a reboot is completely useless, other measures are required here. You can contact the master or fix the breakdown yourself if you are familiar with the repair of equipment. As a rule, the problem lies in the card reader (for example, if you often dropped your phone). Pull out the SIM card and then reinsert it.
Step 4
If the network is not found on the phone again, chances are high that something is wrong with the SIM card itself. Take another and test it on your phone. Is there a connection? So, contact the operator for a card replacement, he will do it absolutely free.
Step 5
Another variant of the incorrect operation of the phone is a "firmware" error. Better to reinstall it or roll back to the previous version of the update.
