Britons now send more than one billion text messages a week -- as many as were sent in the whole of 1999, figures out Monday showed.
People in Britain sent 4,825 billion texts during September 2007, an increase of 25 percent on September last year, according to the Mobile Data Association (MDA).
That adds up to 4,000 text messages a second, or 70 per person each month.
Meanwhile there has been a "significant increase" in businesses communicating with their customers via text, the MDA said.
The group revised its forecast for the total number of texts sent in 2007 from 48 billion to 52 billion following the sharp increase in September.
Last year, 41.8 billion texts were sent in Britain.
"The UK text volumes show no real signs of abating," said MDA chairman Mike Short, adding that Britain is among the top six countries in the world for text messaging.
"While the trend towards operators offering 'all-you-can-eat' tariffs increases, this will act as a catalyst for consumers' passion for all things mobile."
