People hate being nickled and dimed to death, even when they can afford to pay. That’s probably what ticks them off when they read their long-distance telephone bills.

Pretty soon, you’ll be able to put your “phone rage” to good use. Starting Aug. 1, you’ll find better and easier ways of comparing rates and fees.

On the surface, today’s discount plans look super-low-cost. Intense competition in per-minute calling rates has knocked the prices down. Per-minute rates should drop further as long-distance and local-phone companies invade each other’s markets.

But the phone companies keep reaching for revenues in hidden corners surcharges, fees, directory assistance, operator assistance.

By Aug. 1 you should receive a written agreement from your long-distance carrier, disclosing all its rates and terms for state-to-state calls. You’ll also find it on their Web sites.

That will be your moment to shop anew for a long-distance service. It might even be cheaper to drop your long-distance company entirely and use one of the 10-10 “dial around” numbers.

Here’s a shopping guide:

-Basic rates. These are charged to people who haven’t signed up for a discount calling plan. You’re paying the highest rates on the card.

AT & T; just announced an increase in its basic rates, effective July 1. Customers are paying 1.6 percent to 11 percent more, depending on the time of day they call.

The new price range runs from 16 cents a minute (weekends) to 30 cents (weekdays), with no minimum monthly phone-usage fee. If you switched to a basic calling plan, you’d pay 10 cents a minute on Saturday or Sunday. MCI’s charges more on Saturday but matches the 10-cent Sunday rate.

Basic-rate customers generally don’t make a lot of calls. Even so, you’ll save money by making all long-distance calls on Sunday either through MCI or by getting on AT & T;’s Sunday 10-cent plan, said Sam Simon, chairman of the Telecommunications Research & Action Center (TRAC) in Washington.

-Discount plans. All the major long-distance companies offer discounted per-minute rates, going as low as 5 cents. But you’re also charged a monthly fee.

All the rate disclosures should be on the Web sites Aug. 1. The lowest rates often go to people who sign up via Internet and agree to be billed that way.

Discount plans change, so don’t settle into the plan you choose. Keep calling your long-distance company to see if there’s something cheaper.

For free rate comparisons among five long-distance companies, based on specific phone calls, go to trac.org. To find the best carrier (among seven), based on your total calling pattern, send $5 for TRAC’s long-distance comparison chart, P.O. Box 27279, Washington, D.C., 20005. Include a self-addressed business-size envelope and 55 cents in stamps.

-Extras. You’ll find many other fees on your long-distance bill, going by varying names say, fees for connecting to the local phone company, special state charges, subscriber-line charges, directory assistance and a federal universal-service (or “connectivity”) fee.

Some phone companies charge higher fees than others. So shoppers should factor them into the total price.

-Dial-arounds. With these services, you don’t have to sign up with a particular long-distance phone company. You place each call independently, using a 10-10 number.

Some of the10-10s have no minimums, no monthly fees and low per-minute rates. Some give excellent discounts for 10- or 20-minute calls. A few even have no universal-service charges.
