Why it should not? Just use common sense. This application (with database triggers enabled, as per first post) keep and eye on time of You'r every call, + number of sms, if You want it too. You set all parameters manually. So, what is it there, that can work in Antarctica, and can't for India?

As for scripts itself - here in Poland, most operator count free minutes/sms/mms as follows:
1 sms = 1 minute = 1 mms (under 100 kb)

As You can easily presume, it's much more cost effective to always use mms instead of sms - even, when You want to type only text. Is it possible to add any param to count mms just like You did with sms?

I know that this may be complicated, cause mms is suported via fMMS... I don't even know if such a connections are even stored in evenlogger. Especially Havoc mode.

Just my little uneducated suggestion - mms always use different settings (ap) - so maybe tracking data connections from configurable (via user setting it) connection point only (to not confuse it with normal data connections) may help to achieve this? Is data connection stored in eventlogger?
