Hi Alexander,
PS To make it clear, I cloned my own SIM-cards, because I used multi-SIM card with several numbers on a single SIM. So nothing really illegal.
Thank you for the infos.
I wanted to make the same experiments, unfortunately all providers in my country are no more providing "weak and clonable" SIMs.
Which provider's SIMs did you used for that?
Is it still possible with some providers around Europe that i could use with roaming procedures?
Thank you again for attention.
Cheers
Gloria
