The way it works is that a GPRS connection behaves like a VPN tunnel. The module creates the connection, and sends/receives traffic over that connection.

I normally have about 2-3 MB per month now, I guess my maximum would
be around 5 MB.<br>
<br>
Note: that includes GPS logging (streaming) activated, and I'm
driving about 600-700 km per month.<br>
<br>
I also currently use about 50-100 SMS per month, but I could already
cut that down to near 0 by disabling the SMS channel, as I send all
important notifications to the App as well.<br>
<br>

<div>I just got off the phone with Telenor Telematics and they
were very willing to help with telematics SIM card for the
OVMS.</div>
<div>Questions came up about the traffic used and number of
SMSes. </div>
<div>I remember I read some statistics for couple of days of
usage, but I need some very rough averages per month. </div>
<div>Can some of you guys that have been using the system for
some time put some KB numbers, and if you like comment on your
usage.</div>
<div>Thanks,</div>
