Instructions: Remove the SIM lock from the iPhone

Newer iPhones no longer get a SIM lock from the cell phone providers and network operators who sell them with a corresponding contract. Older Apple smartphones such as the iPhone 4 or iPhone SE can still be used with this restriction. This means that you can only use SIM cards from a certain mobile phone provider with these devices - mostly Vodafone or Telekom. To remove the SIM lock from the iPhone, they offer their own options, but these do not always work. You can do a work-around to unlock the device via iTunes on a Mac or PC.

Here are the instructions for removing the SIM lock from the iPhone - easily on a Mac or PC.

Remove the SIM lock from the iPhone

In order to remove the SIM lock on the old iPhone without the original SIM card and thus be able to use discount rates as well as Vodafone or Telekom, you need iTunes. If you have the latest version of the program on your computer, proceed as follows:

  1. Open iTunes and connect the iPhone using the Lighting USB cable
  2. Create iPhone backup (image for data backup)
  3. iPhone Reset to factory settings
  4. Restore the device with the backup created
  5. Switch on the Apple smartphone and use any (active) SIM card

This procedure helped with my wife's iPhone SE after the procedure proposed by Vodafone was unsuccessful. If you want to see the official help for unlocking the iPhone from the network operators, here are the links:
