My Data-plan is Flext 35 (T-Mobile UK). I get 900 Minutes or 1800 Text Messages..
i.e 2 text messages equates 1 minute

I just have 2 questions

1. Does your script count messages as well? If not can your script be enhanced to do it?

2. I am not sure about T-Mobile but some companies charge you by minute i.e even if you talk for say 30 seconds you will still be charged for a minute. Do you round of seconds to minutes?

Regards
