The SIM stores network state information, which is received from the Location Area Identity (LAI). Operator networks are divided into Location Areas, each having a unique LAI number. When the device changes locations, it stores the new LAI to the SIM and sends it back to the operator network with its new location.
Russia Technical Information - In Details. Russia Voltage. The voltage in Russia is 220 V which is the same voltage used in China, Greece, Russia, South Korea, and the United Arab Emirates. 220 V has an advantage over lower voltage such as the 110 V that it is cheaper to transmit.
First, the megohmmeter's output is much higher than that of a multimeter. Voltages of 100, 250, 500, 1,000, 2500, 5,000, and even 10,000V are used (Table 1 below). The most common voltages are 500V and 1,000V. Higher voltages are used to stress an insulation to a greater degree and thus obtain more accurate results.
