I am old user of Nokia E72 and it has got an interesting function that I always used.
But now I moved to Android on an Xperia SL. On my Nokia, the field of recipients allowed me to copy and past the list of contacts separated by linebreak, from a text file.
This worked with even more than 500 contacts at once.
Unfortunately, I cannot do this on my new Xperia.
My Question is: Which SMS App can allow me to send SMS to a list of recipients from a text file?
