As everyone is different, chooses to do things differently & spend their money differently I can appreciate everything you have said.Nope. Not even close. My employer pays for my landline because I need secure DSL, so while I do pay that bill ($24/month), I get reimbursed for it. The cell is $80/year. I do check all the time to make sure that it is still the best deal for us even if we paid it ourselves, and no contract wireless plan even comes close. (And as I said, I don't feel safe in severe weather situations without a phone that does not require electricity to operate. All wireless phones require it, because the transmission towers must have power to move the signal. While some of them have backup generators, not all of them do, and the volume of calls that hits after a disaster will decimate the backup supply very quickly -- that is, assuming that the tower isn't under water.)
It really doesn't matter what I do or don't pay. The fact is, phone service has been a dividing line between the haves and the have-nots since it was first invented. More people have phones now because of pre-paid cell phones, but even those cost something, and with "unlimited" plans appearing to be all that is offered, many people are thinking that they may have to do without again now. I'm really against any kind of community emergency program or school-reach program in a public school that works on the assumption that EVERYONE has a phone, and I'm even more offended by the idea that anyone would assume that everyone's phone service has extra-cost options like caller ID and call-forwarding. They don't, and if pricing trends in the market are anything to go by, they won't any time in my lifetime (text-messaging, yes, but not those services). We should not blithely be willing to dismiss people who for whatever reason cannot afford a phone that is up to contract service standards, and/or who for whatever reason choose not to keep a powered phone on their persons 24/7.
FWIW, I did grow up with a party line, and that is the basis for my phone habits (my family got a private line in 1979, when I was 19.) DH and DS don't use phone service much, either. (The 13 yo has had his own cell for 9 months now -- he has used a total of 28 minutes of voice time and 36 text messages, including the incoming ones.) I'm not a luddite, and I can afford fancier service, but why should I pay for something I will not use? I'd much prefer to put that money into the travel budget. The way that I have it set up now I have access to voice calling, text messaging and mobile internet, but I only have to pay for them when I use them, which is VERY seldom. All that I ask is that others respect my preference not to use my cell for non-essential calling.
If you prefer that people don't call your cell phone the best thing to do is leave it turned off unless you have to use it for an emergency. That way you will not get upset if someone calls your cell #.
As far as Dr's calling or not calling your cell when you have indicated where to call an option would be to call them for any results, etc. from your phone of preference.

I suppose she could cut that down to 45 seconds/day and save some of that extra time for studying though? With unlimited texting you can text people in other carriers and not incur extra charges.
