I only know one person who doesn't have a cell phone. And thats my grandmother. Jeez you guys are low tech. You living in the stone ages or something?

No but seriously this discussion felt a bit odd to me being part of a nation enslaved by cellphones.
And speaking as an inhabitant of said country... Even we don't have 100% coverage here. There are blind spots. But ofcourse common sense applies, don't expect miracles if you're crawling in a thick bush. In general, I have never been totally cut off. Moving around a bit and waving the phone around always gets results. At the very least you'll get a message out.
The speakers making "tyddytyddytyddytyddy" isn't all that bad unless you really obsess about small things. It is very occasional. And when it happens, you remember to check if you have lost your phone or if it's still with you. It always happens if a call or message is coming in, so you can grab the phone before it starts ringing! Now tell me you wouldn't want to have precognitive abilities like that. Too bad I can't impress anyone with that around here anymore.
A word of warning though. You might become dependant on it. When I was a child, people used to plan ahead. Where to meet when to meet and so on. Now we just call.
"What kind of beer you wanted? Oh, k bye" ... "It's me again. You want bottle or can? Sure, bye" ... "I'm where we were supposed to meet! Are you coming or not? Wait I see you now."
