Free text messages in BA through computer

I sent one SMS to myself about 10 minutes ago, and it has still not be delivered.

Did anyone else try to send a SMS to him/herself ?
MMMhhhh, in fact in some cases, the SMS are charged to the RECEIVER !
This is explained here
while very few sources confirm this.

Some operators like mine probably (Claro), do block such SMS and don't accept this charging method.

Can be fun to send SMS to people you don't like though :D
Nice! Anyone know if that works (on Personal) with the dreaded pay-as-you-go non-plans ? (ie I'm sure I will get charged for receiving but will I in fact receive it) - does it work from abroad as well ?
