AT&T, which has taken over Cingular wireless, is also the largest phone company for homes and businesses. Basically, the company wants you to think of AT&T as a single-source provider for every type of telecommunication service you need. The company is now offering a plan known as “Unity,” which combines everything. Clark would call it confusing. In order to get the plan, you have to buy local phone service, buy an option for long distance and buy a wireless plan of $60 or more. It ends up being about $120 a month for all of it. So, what would make that plan worth it? Well, you’ll be able to call any AT&T cell phone or home phone FOR FREE. It wouldn’t count against minutes ever. The only time it would count against your minutes is if you called someone who is not on AT&T for home or business service. So, you have to figure out if it makes sense for you. If you live in an area served by MetroPCS or Cricket, it probably wouldn’t. Those companies offer unlimited local and long distance calls in your home market for $40 a month. But if you travel a lot and use your phone on the road, or if you’re not in a MetroPCS or Cricket, it might be worth your while. Do some homework and decide what’s best for you.
