It is a great web based SMS or TXT sending application. Runs on Firefox, Chrome and iPad's Safari ... and probably many more that I haven't used. For developers there's an API available to attach to your systems. It is probably the least expensive at only 4.07cents (including GST) per 160 chars. Also available is an address book and, VERY importantly, access to your SMS history showing what you wrote, to whom (phone number) and when. Interface is simple, perhaps a bit spartan, but all you need is there, quick and easy. Being a web based application, i.e. "Internet/broadband based" you don't want nor need fancy graphics nor distracting animations that would take time and broadband to load. So far reliability is 100%, not a single failure!. Very pleased with this service. Another big plus is a generous "try before you buy" with 20 (20?) free SMS for you to try and then, later on, decide to spend money charging more SMSs or not. Recommended !!
