Orange has started to roll out a push email service that it hopes will appeal to small businesses, and extend the reach of the technology across the workforce in larger businesses.

Subscribers can choose from eight handsets and at the low end will pay around €10 per month for unlimited email. Higher prices will come with higher-end phones that allow users to download attachments.

Orange customised technology from the French mobile email developer Altexia for the service.

Businesses must install server software behind their firewalls to enable the service, which pushes email, calendar and contact information out to mobile phones. It is compatible with Lotus Notes and Microsoft Exchange.

Customers pay a monthly fee per user, but no licensing fee for the server software, and Orange is offering installation help free of charge.
