While not a surprise to many in the Mobile VoIP space, Tesco has launched their Freshtel Mobile VoIP service in Australia.
Now here's my speculation.
Australia is a wonderful market to trial things in. The country has very solid IP networks from Telstra. It is an English language country. Mobile is well thought of there and in many ways its a greenfield market.
Tesco also has stores in the UK and is expanding into the USA with Freshies. I would expect that over the next few years if Freshtel is a success down under, that Tesco (a company that WalMart views as a rival globally) will be selling this in the UK and USA as well.
