I moved you to the right section, where you have all infos about it. You should ask your supplier, and the 2.30 Sim Team for support.

Or, we created the Japhar Sim for DM520HD exactly for your case, so you can upgrade your box to the Japhar Sim and have support from the Japhar Team. You will find it at http://www.japhar.com/japhar/
