Cellphones


Do you know who invented cellphones? Well a man named Martin Cooper invented cellphones in 1973. His first type of phone that he invented was the Motorola.

We use cellphones to call, text, take photos, take videos, play games and surf the net . Today phones are very expensive and sometimes cheap. They cost between $50 - $1000 to buy one.

The first type of phone brand that was invented by Dr Martin Cooper was the Motorola then a lot more other brands came out such as Nokia, Samsung, Alcatel, L.G, Blackberry, Blueberry and Sony Ericcson.

For credit it is $20 for texting, calling, downloading and much more. To text you use keyboards or if it is touch screen you just touch the keyboards on the phone. Phones need Sim Cards and sometimes Memory cards because without a Sim Card you won’t be able to use the phone. Memory Cards are just so you can store more things in your phone like Music, Images, Ringtones and more.
