Yes I don't know about that. The IP address is lost after a variable length of time sometimes in as little time as an hour. I assummed this was related to the IP loading ?
However I don't have a problem with that. If charge blocks were calculated then it would be a vast improvement on how its operating now.
Do you know someone at vodafone who really knows this stuff ?
Telecom do not bill after 1 minute of inactivity (dormancy) only when a session is terminated (disconnected). That could be after 4 hours, 24 hours or anytime after a device initiates its own disconnect. For up to 24 hours you have one IP number and this is considered a single session. There is no NAT on CDMA, over the CDMA public internet realm the IP addresses are public facing.
Vodafone had free email for several months last year after they launched the blackberry - any email traffic was free no matter if you used a Blackberry or another phone with email such as an SE.
GPRS charging has always had a 10kb minimum session charge so it's always cost you 10c to check your email if you're not on a data plan. If you use any data at all it pays to get a GPRS plan but Vodafone dumping the $5 GPRS plan was a bit of a nuisance for a lot of people - they are either forcing you to pay $10 or face a higher casual data charge.
I'm very confused. My data counter counts 14.1KB of data sent but I wouldn't have gone through more than $30 by now. And I mostly download 64KB games and don't get charged more than a dollar even though I disconnect to try the game after downloading and then download even more games (around 6 times). Maybe we're all in the dark about this one. I have heard the 10c 10KB charge is rounded up only every 10min approx. but the per session argument with changing IPs sounds more realistic. Well I feel like I'm getting away with murder and loving it with the amount of surfing I do (pics turned off though), but its possible there is a kilobit and kilobyte confusion here...?
Standard network practice is MB is megabyte and Mb is megabit.
In general bits are only used to describe network speed while bytes are used to describe the amount of data.
That goes for kilobits (Kb) and kilobytes (KB) too.
Don't worry too much as it's like the French who when they get excited, interchange vous and tu.
But in general you still know what they're saying.
Just look at the above descriptions of data notation.
So given this conversation is about data and not network speed, no one should be referring to bits.
Hope this helps. :-)
Oh, and data used may vary a bit with mail depending on if you using POP or IMAP mail.
How refreshing if Vodafone and or Telecom just published how they calculate data payment. :-)
