In the US, you can get a pre-paid plan. Like 20 cents/message, tops. How many messages do you plan to send, anyway?
I've seen unlimited texting plans for like $10/month that you can cancel anytime.
in contrast the US telcos have been some of the worlds slowest to make the switch.
this is strange because the US telcos are fairly up to date with other technologies. (internet connectivity for example.)
Its the problem of legacy systems - its more profitable to maintain an old system then to throw away everything whenever there is a latest and greatest new technology.
New Yorks subway system is a case in point.
what is interesting is many countries in the developing world now have perfectly functional mobile networks which can be maintained far more cheaply than one of our tecos existing networks because they do not have to maintain a whole bunch of legacy copper.
They also just steal the technology - not paying for research scientists or 'pesky' patents. And quality service isn't included. The employees are dirt cheap, like $2/hour. They spend nothing on safety - the electricians wear a t-shirt, shorts, and flip-flops while balancing 40 feet up on a handmade bamboo ladder while working on 220V power lines.
I paid less than $5/month for my cell service when in Thailand . . . all the text/voice I needed.
