Your post was basically blank @Olegs8357 and the subject line doesn't really clarify what your issue or question is.
If you want to activate a SIM then follow the instructions here:
If that's not the issue then, if you want assistance from the Community Forum then you need to explain clearly what your issue is.
E.g. what exactly are you trying to do, what steps are you taking to do it, what happens/goes wrong, any error messages, etc.?
If you need to contact 48 support about this then see the links in my signature below.
