For those of you that demanded data traffic support for LCMinutes, the wait is finally over. The version 1.30 can monitor data traffic through cellular line (GPRS, HSPA, EVDO, etc), and calculate its charges.
Monthly data traffic limit, or monthly data allowance, is supported, along with rates per kilobyte for extra data. User can also choose whether to round up to next full kilobyte when calculating charges.
If you try it, let me how it works, or not working.
