Be careful of BT's SMS services though -- not only can they not send to non-UK mobile numbers, but they can't even manage to deliver to UK mobiles when they're roaming abroad. You might want to use someone more competent, if that bothers you.
David, This particular service is targeted towards developers wishing to add a comms component to their applications and not necessarily for direct consumer use*. And I can definitely confirm that it works globally and across all networks both in terms of delivery and even while roaming. *you 'll have to write the code yourself to do this or pick up one of their sample apps. -- Otu Ekanem http://rants.ekanem.de
