BT is making it cheaper for firms' employees to take their offices with them using voice over IP-enabled smartphones.
A new £10 a month bolt-on tariff for the VoIP-ready BT Office Anywhere smartphone service gives unlimited e-mail access, unlimited calling between colleagues, unlimited internet phone calls to UK landlines, and the ability to work on Microsoft Office applications.
There is a choice between the HTC S710 or HTC S620 smartphones at no extra cost, when using the service.
Unlimited calls includes those between BT mobiles, back to the office landlines and voicemail.
The sharing of minute bundles between Office Anywhere and other BT mobiles also means no wasted unused minutes.
VoIP calls are made through wireless broadband hotspots, including BT Openzone, or a BT Business Total Broadband hub.
Office Anywhere is also now available minus the VoIP capability, as a £5 a month bolt on.
