| style="text-align: left; background: #F6F6FB;"        | If {{{model|FMBFMB640}}} is in ''Deep Sleep'' mode and an SMS event occurs with ''Low priority'' (which does not wake up {{{model|FMB640}}}), then the device does not send the message. It is saved to device memory until it wakes up from ''Deep Sleep'' mode and GSM modem starts working normally. After it wakes up, all the messages that are saved to memory will be sent, but keep in mind that only 10 messages can be saved to memory – all other messages will not be saved, until there is free memory space.
