which is more reliable? cell phone or landline phone?

Yes! it is better to have one. it can help you save money and it is the fast one. but, what if all networks or a loss of signal? what would you do?

well so far signal is good, besides if emergency really happened then we know each others office phones. or better yet, we will see each other in person if it is really that important. our work place is not that far from each other though.

so which is more RELIABLE? I see you didn't answered the question! I want to know what you think... =)

I remember growing up with "wired" phone...it might have gone down (for a couple hours at a time at most) two or three times in 25 years! that is VERY reliable, as my cell towers have gone down numerous times in just the past year (if only for a few minutes). I don't see how you can say a cell is more 'reliable'...maybe you never had a landline? if you did, can you recall even a single time it failed you? I was hard pressed to recall a time when we were phoneless...there was a huge ice storm many years back, and if there had been cell towers, they would have failed too I'm sure! but I don't have landline any more, because the cell is reliable enough for me, just not AS reliable as a landline...you dig? =)

but, which has the more dis-advantage? isn't it the wireless phone? defend this one.

but can you bring it all the time with you?

yup, you're right. especially on emergency purposes. loss of battery is really a big problem.

but when it loses signal, then is it stull reliable? is it still useful? can still send messages or receive calls? hmmm...what if the battery is down? is it still reliable?
