Can someone explain GPRS a little clearer for a newbie

[madkitty]

OK so Ive installed SPB GPRS monitor but a little confused - I presumed that if you received (for example) 30 emails at 2kb each then your traffic would be 60kb for that session/day etc? Hmmmm there must be something Im missing as the GPRS monitor is always showing a lot higher and also included traffic when I was connected only via my wireless router. Its definitely all set up correctly so perhaps someone could give me a little GPRS lesson? ta x

It also seems to want to increase whenever it feels like it - I turned it on to check the calendar and it increased 6kb LOL

EDIT:
even stranger - I just turned it on to check my calendar and its increased from 93kb to 97kb and I havent sent or received anything yet GPRS is connected....but that should make a difference should it?

I am not an expert on this but here are some basic facts for starters:

1) When checking emails or calendar or whatever, various headers and other data are sent as well so if you have 30 emails at 2Kb each your traffic will exceed 60k because the email program and the server have to talk amongst themselves to let each other know there are new emails and what to download.

2) What do you mean, check the calendar? If you are synchronizing with exchange server then even when your WiFi is connected ActiveSync tends to go for GPRS (thank you M$) and even if there are no new items to download simply checking the calendar might cost you the 6k (I am not sure, but thank M$ again for the protocol)

3) Make sure you don't have any apps in the background that are set to automatically update, like weather plug-ins. Those will connect to GPRS if WiFi isn't present when they need to update. Note that when you put the device on standby, it turns WiFi off, but keeps GPRS on.

Well, hope that shed some light on the issue for you.

that makes things clearer - I also hadnt realised that when I was checking for emails every 10 mins it was costing...I only thought it was when you sent or received them

think we should all get GPRS manual from the network operators :lol:
