That's not exactly true..
Here's an excerpt from the official BB doc:
Content classified as Enterprise data on BlackBerry 10
devices (i.e. work email, attachments, work contacts, calendar
and notes, work browser, and enterprise applications) will
pass through BlackBerry Enterprise Service 10 and will be
compressed. Data that is not classified as work (i.e. personal
browser, personal email and applications) will not pass through
BlackBerry Enterprise Service 10 and will not be compressed.
It is anticipated that the majority of personal data consumption
will not benefit from additional compression due to the nature
of the content (i.e. video streaming, embedded flash content,
music and video downloads, video conferencing, application and
It is exactly true - encrypted data cannot be compressed. Only if you do not use SSL for the ActiveSync traffic there could be a compression - but ActiveSync has GZIP to compress some data build in anyway.
Browser data could be compressed if it is not encrypted. Application Data depends on the application... but there is not that much that can be compressed (try to compress a pptx created with office 2010/2013 and you will see its not more then a few %.
Conclusion: Most traffic is not compressed, even if it passes the MDS CS.

Approx after a month of installing BES 10, we are now able to activate and sync Z10 with our exchange 2003. I have few queries like.....
1.) Mail flow is not fast as it was in BES Exp 5.0.3, mail sending and receiving takes approx 30 to 40 sec.
2.) Lookup is also too slow
3.) Same policy & same email profile but few users get work password prompt, if device is inactive till 20 mins but most of the users doesn't get password prompt even device is kept inactive for an hr.
4.) Earlier in BES Exp 5.0.3, we can found complete device to device mail flow chart, is it possible to get the mail flow chart in between Z10 to Z10, using work account.
5.) Couldn't activate work account using server address.

even this message already a few months ago.. but i can tell you the answer is no encryption.
document are lying but measure the traffic volume in mobile carrier always state the fact...
i knew the answer because i'm working in a mobile carrier and measure it for times.. and the data size of message is even bigger then original....
now UDS have tones of issue and report to them over 2 months without any concerte solution...
BDS also able to work over BB intrastructure and no longer to connect to CAS over internet directly..
I'm also deploy MI and GFE product... and both products are even better than BES10 now...
Interesting. BlackBerry claim that all data that passes via MDS-CS is compressed. Where do you get your information from? I would be surprised if they hasn't used some sort of technology on BDS to compress even further.
I will ask BlackBerry for more info on this and get back to you.
