Data charge fro MT4 Mobile

 
Hi, I am in New Zealand. Vodafone run our GPRS/WAP enabled mobile phone system. How much data will I have to pay for if I run MT4 mobile? Are there some figures on how many MB/hour I am likely to run up. Thanks in advance.
 
The traffic should be close to the traffic of your MetaTrader 4 Client Terminal on your personal computer.
