I'm rather amazed by the comments here. You Europeans seem to think that we Americans ride horses to work or something.
The American mobile system works much better than the European one. Prices have fallen, penetration has risen, and average usage has skyrocketed. Almost everybody in the US who wants a mobile has one, from at least middle-school age. (A few really remote areas have little or no coverage, but that's a function of terrain and population density.)
Average usage per mobile phone in the US is approaching 1000 minutes/month. I don't have the exact number (Scott Marcus of WIK, who co-wrote that report, probably does -- we are old friends) but it has been rising. We do not see it as paying for incoming calls, either, because we pay so little for mobile usage. Everybody signs up for a bucket-of-minutes rate, except for the prepaid phones (which are also available). So we pay maybe $40/month for 500 minutes, or $65 for 1000 minutes; fully unmetered plans (about $90) have also just arrived. Overtime is expensive, so users make sure their bucket is big enough.
In some major cities, calling volume to and from mobiles exceeds wireline levels. So there's a lot of wireline substitution going on. Mobile phones have regular-looking numbers so you can just give that number out. Numbers are portable, both among wireless carriers and between wireline and wireless. So you can drop your wireline service and keep the number on your mobile.
Telemarketing calls to cell phones are illegal, subject to heavy fines if they're caught. It's up to the telemarketer to figure out if a line is mobile. It still happens, but it's rare, and nobody worries about the minutes, since they're bucketed.
Somebody said that Americans still use pagers because of our mobile rates. That may have been true in, say, 1994, but the pager business has shriveled to vestigial levels. There's no big cost advantage to them. But some locations, like hospitals, don't like cell phones to be turned on (the transmitter might interfere with something), hence pagers.
Many Americans no longer pay domestic long distance charges either. Mobile plans almost never charge for such calls; wireline plans are common too. So it's common for college kids to have home-area cell phones and call each other on them, around the campus, even if the call hairpins through the called party's home area 3000 miles away. It's all included in the plan.
For all of this, the wireless companies are profitable; Verizon and ATT are shriveling on the wireline side but making up for it with wireless profits. Talk about moving to a CPP plan, like Europe has, are about as popular as talk about moving to a Soviet-style planned economy. Our mobile system works. Our wireline system is a regulatory mess, to be sure, and let's not talk about Internet or broadband. Wireless works, it seems, because the current FCC (Cheney-Rove regime) hasn't touched the system that was put in place before them.
Texting is expensive if you don't have a bucket-of-messages plan. Unlike Europe, talk is usually cheaper. But 500-message and even unlimited texting plans are now available; they're popular among young users.
