-‘Security’
-‘Set up SIM card lock’
-Uncheck the box next to ‘Lock SIM card’

iPhone:
WARNING! Most iPhones use a SIM card in the so-called nano-size. If you would like to use an
iPhone for this procedure, you will have to make sure the SIM card is resized to fit in the
iPhone. By doing so, a convertor is necessary to fit the SIM card in the GPRS Monitoring Gatway
afterwards.
