each message has an ad attached - the test I used had "get your free sms at www.mobik.com" attached.
Worldwide coverage but each message you send is appended with an 'ad tag' from their sponsors. MobiK will not deliver a TXT message unless there is an 'ad sponsor' in your region. View their coverage page for the latest summary of 'ad sponsored' regions.
They say if you have a ported number (eg Testra number - like 043XXX) and its now with another carrier (Optus) then the message may not be delivered. In my case this was delivered ok.
Havent tried with it on my mobile as it needs a java application installed and my phone doesn't Java
Nice.
Gizmo has also recently released free SMS site, but I tried it to SMS my phone, and hasn't received it after 24 hours.
My number has been ported 3-4 times though. Not sure whether it is causing issues. I might give this one a try.
