What to write when advertising a phone?

Advertisements need to be short and to the point. Never use two Words when one will do. You need to say 'what it is, what is does and what's in it for you, the user'.

Example.....A phone for sale (state colour and size of keys)

It performs very well

You get clear reception from anywhere.

Call this number for proof of performance

Put this into your own Words, invite people to telephone you and then sell the product verbally, using your own personality
