A. Depending on the usage, between 10MB up to 100MB. A VPN tunnel takes approximately 18MB per month on overhead. For permanent data streaming (e.g. using Modbus TCP/IP) a data flat rate is recommended. For sporadic access like download of data log files, the volumes are typically less than 20MB. Some phone and M2M companies offer a web based status page to observe the data volume.
