Update: if you want to make both SIM cards available at all times in dual SIM version of Moto G (all Moto G generations) so that you will not miss any calls (even when you are talking over one SIM card) , you may follow this guide to set up call forwarding and call waiting.
In some regions, Moto G supports dual SIM cards. In other words, you can use up to two SIM cards simultaneously.
But Moto G dual SIM (and Moto E, Moto X and Moto Z) phones are dual standby, NOT dual active. Please refer to this dual SIM Android phone guide on differences between dual standby and dual active in dual SIM phones.

How to access Moto G dual SIM settings?
All the settings related to Moto G dual SIM cards can be accessed through Settings— Dual SIM settings.
You can choose icon colors for each SIM card, choose the SIM card used for mobile data.
Please note, only one SIM card can be used for 3G. The other one can only be on 2G.
If you are using one SIM card, you can ignore all setting here. The settings here are only relevant to owners who are using two SIM cards on the Moto G.
How to get rid of the Moto G SIM card selection when making a call?
By default, when you dial a number, you will be asked for the SIM card to be used for that call. This is useful if you want to use different SIM cards for different numbers, and you need switch them frequently.
However, this can be annoying when you mainly use only one of the SIM cards for outgoing calls.
It is easy to designate one of the SIM card for all of your outgoing calls. You can go to Settings–Dual SIM settings– Call settings, tap Making calls. Then you have 3 options:
- use SIM card 1
- use SIM card 2
- let you select each time (this is the default setting).
How to use Moto G automatic SIM selection?
Moto G also has a nice feature in dual SIM cards models for those who have to switch between SIM cards for outgoing calls. This feature is named as automatic SIM selection. This feature is valid only when “Ask every time I make a call” is selected in making calls.
Automatic SIM selection is a software solution that helps you select the SIM card to be used automatically. It will learn from pattern of SIM card usage and suggest or even automatically select your preferred SIM.
This means there is a learning process because Moto G has no idea which SIM card to be used initially. You need train it by turning on “Ask every time I make a call”. Gradually, the software will understand the patterns of SIM card usage. When you place a call, it will predicate which SIM card should be used and select it for you automatically.
This feature is one step forward compared to checking “Remember SIM for number”. For numbers you never called, automatic SIM selection often can select the correct SIM card for you based on the contact group, incoming calls and some other contact info in the address book.
If you find the automatic SIM selection chooses wrong SIM card, or if you want to change SIM card for that specific call, you can always tap the “Change SIM button” when Moto G is dialing the number (as shown below).
If you want to play safe, you can disable automatic SIM selection. In this case, the software still learns your SIM card usage patterns and gives you suggestions based on calling history.
How to divert the incoming call for non-data enabled SIM card to voicemail when mobile data are used?
A dual standby dual SIM phone only allows one voice or one mobile data to be active at any time. They can be in standby simultaneously. This usually is referred as dual standby. it is different from dual -active ones, which allows you to use 2 SIM cards simultaneously.
When one SIM card is used for voice or mobile data, the other SIM card can only be in standby mode. Moto G is not an exception.
So, for example, when you are actively using mobile data in SIM card 1, if there is an incoming call for SIM card 2, you will have 2 options:
- Stop data transfer in SIM card 1, and pick up the incoming call in SIM card 2 (this is the default setting), or
- Divert the incoming call to voicemail, and continue the mobile data transfer.
Moto G allows you to choose one of the behavior. The default is the first one. If you want, you can change this so that the incoming calls for non-data enabled SIM card are diverted to voicemail if the data enabled SIM card is actively transmitting data.
You can access the settings at Settings–Dual SIM settings–Connection priority. If you set the connection priority to voice, the dual SIM cards will behave as the first option. If you set the connection priority to data, dual SIM cards will behave as option 2.
