Maxxina: short answer is no however in my experience is that you usually have to sign up for those that allow you to send via internet and then they are from your country of origin as they ask what your mobile number is. So you will probably have to do a search on the internet.
Here is Australia, I'm able to sms overseas from my mobile at the same cost as if I were smsing to another aussie mobile number. I use it a lot to keep in contact with my fiance' that way.
