Do you have a cell phone?
Sometimes I'm at places, and it's crazy to think how many waves are coming down around me simultaneously considerng how many people seem to have a cell phone. Granted, I have one too, but it's still crazy.
Also, what service plan do you have? I have Cricket; I have unlimited calling, 500 free long distance minutes, caller id, call waiting, 3 way calling, unlimited text messaging, and maybe some other features. I pay $45 a month for it. I like the plan, because I don't have to worry about sending too many messages or being on the phone too much.
