Hey there Nouman Al Bakri,

It sounds like you have a SIM PIN that is preventing you from finishing your restore of the iPhone 5s. These steps should help you resolve that:

Restoring

When restoring the device, you will need to unlock the SIM card to complete the restore process. The device and iTunes display the following prompts to notify you:

To complete the restore process:

1. Disconnect the device from your computer.
2. Tap Unlock on the device.
3. Enter the SIM PIN to unlock the SIM card.
4. Reconnect the device to your computer.

If this is not the case, can you elaborate on what the message says that you are getting?

Take care,
