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.
(1.35 volt is the correct and original voltage that Bulova engineered and designed to run properly in all of their Accutron 214 and 218 watches!!) These batteries are the proper Power Cells for EITHER 214 or 218 Accutron Models.
