How did the cell phone impact America?

The invention of the telephone made a very big change in the Americas. For one, people no longer had to wait for responses to a telegram that they may have sent two long and miserable weeks ago. Anyway, the telephone also sped up conversations. If someone needed to talk to someone, they wouldn't have to worry about tracking them down to talk to them face to face. When the telephone, invented by Alexander Graham Bell Elisha Gray, first made its big appearance, people started to buy and buy these expensive items. People never have to send slow telegrams ever again, that is, if A) they can't afford a telephone, or B) their telephone breaks or stops working. I gotta tell you, that would suck to go back to sending telegrams every single second of the day. I mean, who wants that, right? Hope this information helps =))

Where can you find a free cell phone without paying anything?

Yes you can...In most cases the large wireless retailers will require a security deposit ($300.00 - 1000.00 dollars) if you do not have established credit. The other option is prepaid wireless service where each call you make will cost you .12 cents per minute and .15 cents per text message...this is a very costly way to go. An alternative is the company I have service with Apex Global Wireless. They got me set up without a credit check, no security deposit. i have a regular monthly plan on Verizon wireless. it was real easy to get started with them. I was set up fast with my monthly talk and text plan. check out their website...i highly recommend them to anyone that has no credit or damaged credit like i did.
