Du Business Circle Plan SMS Rate

I have been enjoying the older technology of sms lately.  I was assuming that under DU's Business Circle Plan, sms between people in the circle is free.  I was wrong.

DU has been charging 18 Fils for each sms I send.  Though calls are free, I feel that some situation is better to be "texted" rather than to talk over the phone. :-)

This plan reminds me of Unli plans in the Philippines.  The only difference, your circle is bigger.  You get unlimited service if you contact someone using the same telephone network.  It would be great if DU can offer the same promos here in Dubai.
