But, again, only when I have the phone on. That's why it takes a measurable amount of time to get service (and even to find out what provider serves your area) at initial power on. When I turn the phone off, none of that communication is necessary. Note that I mean "powered down" as much as possible; I don't mean simply having hung up the phone so no calls are active. The phone company absolutely does not need to have this information until such time as I turn the phone on again - all calls get routed to voice mail (if applicable) until I choose to re-enable phone service. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
