GSM codes for mobiles
GSM codes are code numbers which allow all mobiles worldwide on the mobile phone network
to set the various functions easily, thus preventing painstaking queries and entries in the menu
of the mobile phone.
GSM codes often vary between mobile phone network operators. Please contact your
mobile phone network operator if the codes listed below do not work on your phone.
• When you have entered a code, you must press the large green Enter key
