Alltel, AT&T (Cingular), and Verizon will be ending their analog cellular service next year, as only ~0.04% of their customers are still using analog phones.

So if you're shopping for an older vehicle that has a telematics system (such as GM's OnStar) you'll want to make sure it either already runs on a digital connection, or can be converted to a digitial signal before writing out that check.
