How to manage & operate your dual-sim Xiaomi Redmi phone viz Internet data, Calls , SMS

1. What are the mobile networks that are supported by the 2 SIM card slots ?

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.

3. How do I know the signal strengths of the 2 mobile networks ?
