Why must they use fixed phonelines?

Just popped to my mind. A question from M1. Why do they have to use fixed phonelines for transporting their "souls" in and out of the Matrix, when they can call in/our using mobile phones?

Any theories? Any clues from the movie I missed? Or did they simply not see the obvious solution?

I think the cell phone conversation travels along the connection they have with the matrix along the hard line at the same time they are trying to make the call.

I think it's the same question as 'how do people check email while connected to the internet to surf webpages'.

Same connection, different 'program'.

Make sense?

Hmm, I'm not too convinced :)
After all the main issue should be to get a connection, to locate each other. Since it is in the Matrix the actual phone cable is not real anyway, so why does it still seem superior to the mobile connection?
Maybe I am just lost in details here :)

The thing with the phone line is that it is a virtual "back door" so to speak. If you notice, they can't use just any old phone line, It has to be a specific phone in a specific location.

Think of it like how hackers infiltrate Servers in this day and age, they can only hack servers that have certain vulnerabilities. Those phone lines represent those vulnerabilities within the matrix. No the phone line doesn't actually exist, but it is a program within the matrix, and like with any program there can always be a vulnerability. If you also notice, they never use the same phone twice.

convinced yet? :)

Yeah - getting close to something I can go to rest with now. Your explanation is good.

Morpheus's ship isn't on a long phone line as far as i can tell. Why do they only need a "land" line in the matrix, if they don't need one to tap the code and enter it?
