Google for free SMS - textport.com works here in the USA and is free. In the USA both the sender and recipient get charged for texts/calls on the mobile networks.
Ive just spent a week in india and massively reduced my costs (down to only £100....) but using wifi and emailing and using skype-skype calls on my phone.
I have tried a few sites now, one said it sent it.
I sent it to myself as a test.
I want to send a text to someone who does not have internet so email wont work, thats why i asked for text.
