Dual Sim function

This is a dual SIM phone, and as such it has two regular size SIM slots under the battery cover.

The phone is able to receive calls on either SIM (dual standby), but the moment a call comes in on either one of the SIMs, the other one will go offline and as such is unreachable.

The phone has a "Dual SIM always on" mode, but when activated this just tries to enable call-forwarding on your SIMs. Such that when you get an incomming call on SIM 1 (which will force SIM 2 offline), and someone tries to call you on SIM 2, that the provider for SIM 2 forwards your calls to SIM 1. On your phone you will then get a second incomming call on SIM 1, which you can answer.

This has however cost implecations. Your provider will charge you for forwarding those calls. Also, call-forwarding cannot always be enabled, especially with SIM cards from different countries this tends not to work.
