I think i understand what you're both saying but i've even sent SMS messages to myself and people in Canada and they read them free of charge. Just a small advert on the text, E.g:
Admin@Text4free.net <message here> sent from text4free
Or something similar atleast.
I'm really in dissbelief of what you say about the costs and having to reply to view the message so I'll tell you step by step how i would send a message from text4free;
1. Go to
http://www.text4free.net/ (obviously!)
2. Scroll down to 'Send Free SMS' on the homepage. (again pretty obvious)
3. Enter the cellphone number and network. E.g 07***** / O2 (UK) in my case. Ignoring 'Any <country> Provider' at the top of the list, those seem to fail pretty bad and are not connected to text4free.
4. Enter the message (obviously!)
5. Enter security code (obvious again)
6. Push send!
Again i'll mention; The top few listings for the 'Provider' being 'Any <country> Provider' are the only ones that don't work for me (maybe thats what you guys are talking about?). I make sure i know the contacts real provider and select it individually.
