Once each command has been entered, if it is a network command (as opposed to a local handset command) it must be transmitted to the network by pressing the YES (receiver) key which acts as an enter key - this is represented here with the © character. Always enter numbers in full international format +CountryAreaNumber ( e.g. +447712345678).
