Cell phone or Mobile phone?
What is correct: cell phone or mobile phone ? Same thing. The word cell is short for cellular and has been used since Bell Laboratories set up the first wireless telephony system in 1947. It consisted of a network of low-powered transmitters, each placed to cover a small region or cell.
The first public cell phone call was made on April 3, 1973 by Martin Cooper of Motorola. Commercial cell phones were introduced in Chicago in 1978 and in Europe in 1981. The first portable cell phone available to the public, the Motorola DynaTAC 8000X, was launched in 1984 and weighed 2 lbs. If you’re surprised to learn that mobile telephony has been around so long, here’s another surprise: Bell Laboratories invented the videophone in 1927.

Numbers
Most numbers on a phone keypad have letters assigned to them. For instance, the letters for the number 2 are a, b and c. But there are no letters assigned to the numbers 1 and 0. These numbers remain unassigned because they are so-called flag numbers, kept for special purposes such as emergency or operator services. Previously, Q and Z were not included on the keypad, meaning that you could not dial a word such as Quincy. Q is now assigned to the number 7, and Z to number 9.
