When cordless phones are not available, there will be always the corded ones.For some reason, establishments like banks require their customers to have a land line before opening a bank account. Even PayPal won't let you open a bank account if you do not have a land line. It's probably for safety measures, that they may be able to call you in a more reliable and secure system.
I ask, however: Is it not unfair?
For people like me, who does not have a land line, it is difficult to make such bank accounts. You see, I do not have any much use for a land line as I am almost always out of the house, which is why I prefer mobile phones even though it's insecure--but hey! who will be spying on me, anyway? Furthermore, I have to consider that I cannot possibly pay for both a land line and a mobile phone. Very unfortunate, I know. 
On the other side of the spectrum, however, land lines are, well, good for businesses, offices, and the like, as they are more noticeable--and again, secure--than mobile phones. That is probably another reason why banks require land lines--they want to know if you are really serious, if you really mean business here. They want to know if you are creditable enough to buy meters upon meters of phone wire for your business or home office--not to mention the phone unit itself.
Whatever the kind of phone unit you opt to choose (or both, if you can manage the bills unlike me haha), I just hope that banks will consider mobile phones as important as land lines. That's all. So that I could transact business. So that we could ALL transact business.
