Freee? You must be fracking mad!
You mentioned the words Telkom, and "free" in the same sentence. And then you expanded it it "cellular" by using the word "SMS".
If you think there's "free" anywhere in that process you MUST BE MAD.
(of course, if theres' some cool loophole I dunno about, then fscking awesome!)
Answer to your question. I don't know.

Hah.!
