While both card slots accept SIM cards with data connectivity, only the left slot supports 3G mobile data (WCDMA/GSM) while the right slot is rated for 2G data connectivity (GSM). And, for your information, you need normal sized SIM cards for the 2 slots.
2. What mode does the dual-sim work in ?
The Redmi supports dual-standby, which means both SIM cards are active to receive calls and text messages. But when you’re using SIM 1 and another person is calling on SIM 2, he/she will hear the message “not reachable, try again later”or the call goes straight to the voice mailbox.
One workaround for this problem is to forward calls between these 2 numbers. When SIM 1 is engaged, the calls to SIM2 will be forwarded to SIM1 and notify you that there’s an incoming call.![](http://en.miui.com/data/attachment/forum/201405/07/094617ggjtn77jz901t07t.jpg.thumb.jpg)
