Is there any limit with the length of the data to cipher on 3DES

Recently, I have been trying to use 3DES to cipher data. Now I wanna know if there is any limit with the length of the data to cipher on 3DES. In fact, I am able to cipher data with length 8 bytes,16 bytes. For other length, I will get "6F00". Why? Is their any limit?

create MF in SCosta card

I have a SCosta card. And I want to create MF in this card. The APDUs command I send is as follow:

>> 00 E0 00 00 02 3F 00
<< 6A 80

As you see, it returns 6A 80, which means incorrect parameters. Please tell me where is wrong and how to create MF in SCOSTA card successfully.

Memory on java card

If .cap file is 2k, I wonder how I can know the memory that the applet uses on the card and if I instantiate this applet on the card, how much memory it will consume?

How to write Ki and IMSI codes to card

I am very glad to join in JavaCardOS community. I want to know if it is feasible to write Ki and IMSI codes to card.
In my opinion, after I do this, I will have a real gsm sim-card? Am I right?
