As usual it comes with some caveats though. Be aware of the fine print.
Vodafone last year introduced a $5 a day international roaming option covering selected countries and the company now has new small business plans that automatically include this feature.
The idea is that when customers use their phones in one of the 46 supported countries (US, UK, New Zealand and certain European and Asian destinations) they are charged an extra $5 a day, but then pay the same rate for calls, texts and data as they would in Australia.
This means plan inclusions can be used overseas without incurring the usual roaming surcharges that can lead to bill shock especially when using data or receiving calls.
But be aware that calls to non-Australian numbers - including those within the country you are visiting - are charged as if they were being made from Australia and will come out of the plan's "included value" until it is used up, so a degree of bill shock is still possible.
The new Vodafone Red Business Shared Plans allow the inclusions to be shared between two and 100 users depending on the plan selected. Plans start at $135 per month on a 'BYO phone' basis, including unlimited standard national calls, national and international SMS, and voicemail, as well as 3GB of data. Additional blocks of data range from $20 for 2GB to $500 for 100GB per month, while tablets and mobile broadband dongles can be added to a plan for an extra $10 per SIM per month.
Plans incorporating an allowance towards the cost of new handsets are also available, and may present better value in some circumstances.
As usual, it's important to carefully consider your actual usage patterns before picking a carrier and plan. For example, Amaysim still offers a $39.90 plan with unlimited standard calls and SMS within Australia plus 4GB of data, which is less than Vodafone's new plans charge just for adding another handset to the account without increasing the pool of inclusions. But then Amaysim uses the Optus 3G network, whereas the Vodafone plans use 4G where available.
On the other hand, Amaysim's international roaming charges add up quickly - $1 per minute to receive a call, $1-$3 per minute to call within the country, $2-$6 per minute to call outside the country, and 75c per SMS.
So just one call from home could easily cost you more than Vodafone's $5 roaming charge. And you would want to think very carefully about using Amaysim mobile data if our arithmetic is correct.
