tbr on irc said:
16:16 < tbr> coderus: that sounds like a dangerous misinterpretation of what a PDP context is
16:21 < tbr> coderus: a PDP context is just a "data pipe", which can have a type of PPP, IPv4, IPv6 and IPv4&IPv6 (IIRC)
16:22 < tbr> PPP was never really common, maybe in the beginning. nowadays the IPv4 type is most common.
16:23 < tbr> multiple contexts are used to establish a connection to: the internet, the mms network, a experimental ipv6 APN, etc
16:24 < tbr> so it won't do ANYTHING for your download speed to increase this value, as it only makes sense to have ONE IPv4 address towards "teh intarwebz™". Also it's unrelated to the air interface data rate.

So It will not make improvement.
So why it is configurable ? Depending on the modem spec for MultiRAB ?

I did modify the /system/csc/customer.xml on android with value of <NbMaxPDP>10</NbMaxPDP>
And I could see the difference when browsing.
The download bit rate is the same but there are more channels to donwload. So the buffers are filled faster.
If my souvenirs are correct, in 2G, 11 or 21 PDP context were possible...
If i look on ofono the MAX_PDP_CONTEXTS is define to 2 in the RIL and 4 for st-ericsson part.
Is there another config-file, for operators, that manage the number of PDP context ? (this would avoid to recompile the modem binary)
