"The * Duos allows for both SIM cards to be active simultaneously, meaning that you can receive a call on one SIM even while you are on a call with the other. What happens is that calls from your other SIM are forwarded to your currently active SIM's network, which you can put on hold to answer (this might incur additional network charges)."
De jó lenne, ha több DSA telefon kerülne elő.
