[Globalplatform-users] Global Platform and Off-Card Entity communication with SMS

[גל ב. <gal...@gm...>]

Hello Global Platform mail list,

I'm a student and I'm studying about UICC and OTA.

I got some questions and it will be awesome if someone would answer me :

1. In theory, the GET DATA, MANAGE CHANNEL, SELECT and INITIALIZE UPDATE
command can be executed by an off card entity without authentication?

2. When sending a SMS-PP Data Download envelope, which is not formatted
according to the 23.048 specification, which component (SD or app) process
it?

3. I got a strange behavior (in my opinion) - for every SMS I sent to my
SIM card with an APDU without the 23.048 headers, I got the 9000 response.
Why does it happening?

Many thanks in advance!
