Vodafone Australia is extending the availability of its $5 per day international roaming offer to the small and medium business (SMB) sector.

The telecommunications provider first launched the roaming service to consumers in July 2013 on the back of deals with partner carriers in the UK, NZ, and the US. It was then expanded to Europe in October and Asia in January this year.

The push to businesses will allow SMBs to use existing Vodafone Red Business Shared Plans as usual in 46 countries for a fee of $5 per day.

"SMEs are increasingly moving away from expensive cable and fixed wireless connections, which makes sense as typically, telecommunications is among the highest operational costs for a SME, after premises and staffing," Vodafone Australia director of sales, Ben McIntosh, said.

According to the Vodafone, the number of business trips taken overseas has increase by 59 per cent over the past decade.

"Vodafone's business customers have told us very clearly what they need from us is the ability to travel to do business without having to worry about a rogue bill coming in from a short business trip overseas."
