Sending SMS from your mobile web app

If you have a need to send SMS messages, whether from a mobile web app or just from your website, I can heartily recommend txtlocal.co.uk

They have a JSON API which makes usage a breeze and you can purchase as little as 100 credits (for just £5 at the time of writing).

I used their service to send texts from an iPhone web app I made just before Christmas – it worked an absolute treat.
