Simore Platinum working solution.

I made a mod.post because I reflashed my N900 and this didn't work correctly due to security reasons ....

(you have to xterminal and root access)

I bought simore platinum for my N900, but it didn't work.
I was realli angry about the support, they replied an absolutely unuseable answer for my question.

My solution (my college helped me a lot)

Manual method:

1.
dial #11 to activate SIM1 (you got general error, no problem)
(or dial #22 for SIM2)

2. root shell and kill csd
(xterminal and sudo -s probably)
killall csd

After that N900 will ask your pin code (if is set) and register the new card. It takes some seconds.

Automatic mode:

1. edit a script: /usr/bin/changesim :

#!/bin/sh
/usr/bin/dbus-send --system --dest=com.nokia.csd.Call --type=method_call --print /com/nokia/csd/call com.nokia.csd.Call.CreateWith string:"$1" uint32:0
sleep 1
/usr/bin/killall csd
#end script

2. run right for this script:
chmod 755 /usr/bin/changesim

3. Create icons to apllications:
edit a file in /usr/share/application/hildon/sim1.desktop

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Name=Company
Comment=Company SIM1
Exec=/usr/bin/sudo /usr/bin/changesim "#11"
Icon=general_synchronization
Terminal=true
Type=Application
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable

4. edit a file in /usr/share/application/hildon/sim2.desktop
[Desktop Entry]
Encoding=UTF-8
Version=1.0
Name=Home
Comment=Home SIM2
Exec=/usr/bin/sudo /usr/bin/changesim "#22"
Icon=general_synchronization
Terminal=true
Type=Application
X-HildonDesk-ShowInToolbar=true
X-Osso-Type=application/x-executable

5. Two icons appear among applications and you can "Add shortcut" them to the desktop.

6. Enjoy! :-)
I attached these files, you HAVE to rename them
-without .txt
-replace "_" to ".".

Cheers, fido
