Do cellphone companies automatically record/store users' convos?

yes, they record.

I once asked my phone company if this was the case because I heard weird echos and clicking while talking and the guy laughed like the jokers and completely blew off the question. The echos and clicking continue

fuck them

no. they do not.

think of the resources and space needed to record and store all that data for millions of customers. even text messages are cleared on a rolling bases.

RESOURCES ARE PRETTY MUCH FREE YOU FUCKING IDIOT ALL YOU NEED IS A FEW THOUSAND DOLLARS TO BUY SERVERS WITH HUGE HARD DRIVE RACKS ON GIGABYTE DRIVES ALL LINKED TOGETHER CAN BE CREATED FOR NOT THAT MUCH AND THINK OF THE POTENTIAL DATA MINING REVENUES STREAMS THEY PROBABLY ARE GETTING

No they do not. Requires too much server space. Costs too much money.

YES THEY DO SERVER SPACE IS CHEAP FOR A COMPANY WITH MILLIONS THEY CAN SPEND A BIT

DUH Of course they do.
They have methods of mass digital storage that you and I have not even HEARD of yet.
wake up!

compression algorithms work quite nicely for database storage

Ever heard of------why is it called----World Wide Web? Everything is recorded/stored.Retrieving it or monitoring it is a whole nuther ballgame.Personally,everything I have ever written on-line is a lie.

Yes, they do. For one year in the US. The storage is very cheap these days.
