It works fine! Only pay attention that SIM card format is "mini" in my opinion, not micro, but anyway I used the adapter coming directly with my SIM and it worked perfectly. After that I set only new password and then the controller workedperfectly responding to commands.
Probably I was wrong, it's really a micro SIM. Anyway positive 100% as I've told. Recommended product and seller!
perfect. It arrived exremlly fast.
