the only problem what i have with BHuvan goyal's ICS AOKP beta 2.1 is, that it doesn't handle my MVNO (mobile virtual network operator)
http://en.wikipedia.org/wiki/Mobile_virtual_network_operator
as home-net. By default it classifies it as net used by roaming.
This is somehow annoying, and can be financially dangerous, when one allows "data on roaming" by default and "automatically select operator network".

On Samsung-GB-ROM's there was a solution for this behaviour which i described already here

But i found a dirty hack, which solves at least the nasty roaming - sign problem, so that i get at least the H, 3G or E signs instead of the odd R sign above the field-strength symbol.

i use this script, which is started as root-user automatically at boot-time

Code:

#!/system/bin/sh

getprop | grep operator
echo bobA1 start

setprop gsm.sim.operator.alpha "A1"
setprop gsm.operator.isroaming false

getprop | grep operator
echo bobA1 done

it needs some explanation:

MCC - mobile country code, 232 = Austria
MNC - mobile network code, different network operators in this country
see
http://en.wikipedia.org/wiki/Mobile_Network_Code


my MVNO provider is "bob", MCC=232, MNC=11 (23211)

bob's home-net is "A1", MCC=232, MNC=01 (23201)


what it basically does is the following:

1.) overrrides the name of the operator, which is stored on the sim card, from "bob" to "A1", so that it matches the operator name given by the network.

Code:

setprop gsm.sim.operator.alpha "A1"

and

2.) overrrides the roaming status flag.

Code:

setprop gsm.operator.isroaming false

the rest ist only a status output primarily for debugging that one can see what was stored in these properties before and after the hack.

This overridden properties are valid until a Flightmode setting or until a reboot.

The effect of this change is only, that the roaming sign "R" disappears and does not reappear, because the strings stored in
[gsm.operator.alpha] and [gsm.sim.operator.alpha] are now ident.

One can now disable "data on roaming" and enable "automatically select operator network" safely, because when you get out of the range of the A1 network, the roaming flag is automatically reset by the OS after changing to another countrys network operator, where we are really roaming as intended, and therefore do not want to allow data because of high roaming costs.

Hope this helps for all suffering by the national roaming MVNO problem.
Hope also that this issue get's fixed one day by the ROM devs.
