If you can't enable Location Services, it may be disabled through the "Restrictions" menu. You can change your Restrictions from the Settings menu. This is located in the third menu of settings options. If Restrictions are enabled, you'll be prompted for your Restrictions passcode.  If you can't remember your Restrictions passcode, try 1111 or 0000. If you have completely forgotten your Restrictions passcode, you'll need to restore your iOS device through iTunes to reset it. See Restore an iPhone for details. Make sure to backup any important data before restoring. This will be under the “Privacy” section. This will enable you to turn on Location Services. You can find this directly below the “Allow Changes” option.
