Introduction to  4


The SIM card of 4 mobile phone is SIM card and does not need card cutting. We can directly insert the SIM card into the mobile phone, but because the cell phone card slot is located at the top of the body, the plug-in SIM card slot is used. Therefore, SIM cards like Apple phones need to be installed. However, this pin is provided when the phone is bought.

In fact, we can use a PIN to operate it. We inserted a small hole near the SIM card on the top of the body in the mobile phone, and we cannot bring the SIM card slot out with a little force. Now we only need to put the SIM card into the card slot, then you can install it again.
