How to get rid of a foreign phone call?

As many as one in three Australians use their mobile phone outside their home country to text friends and family members, according to a new study.

In a survey of more than 5,000 people across the country, researchers found the majority of people in Australia used their mobile phones to text and call friends and relatives in other countries.

They also reported spending a significant amount of time using their phones in Australia, including over 90 per cent who said they had been texting while driving or waiting in a queue for a bus or train.

The report from research firm StatCounter, released on Tuesday, also found people in Melbourne spent an average of 13.5 hours a day using their mobile to text.

People in Canberra spent the most time using it at just under six hours a week, while Sydney residents spent the least time at more than four hours a month.

It was the first time the study had looked at the use of mobile phones outside of Australia.

It found Australians in Victoria and NSW were the most likely to text in other languages while driving, and the most frequent users of mobile text messaging while waiting for a train or bus.

While the majority had no mobile phone use while driving in Australia in the past year, the study found almost two-thirds had done so in the last 12 months.

More than half of those surveyed said they used their phones to make phone calls or send messages to people overseas.
