What is a dual-SIM smartphone?

A dual-SIM smartphone is exactly what it sounds like. It's a mobile phone that allows you to simultaneously use two SIMs. This can be extremely useful when trying to strike a balance between a personal number and professional/business number. It essentially negates the need to have two mobile phones, which also makes them very environmentally-friendly mobiles. The best dual-SIM smartphones will allow users to seamlessly switch between SIMs.

How does a dual-SIM smartphone work?

Setting up a dual-SIM smartphone is super easy, but it tends to always depend on the handset in question. Some dual-SIM smartphones still require two physical SIMs, whereas other more modern devices require just one physical SIM, and then an e-SIM (digital SIM).

Two types of dual SIM:

DSDA: Dual Sim Dual Active - when both SIMs are constantly connected. This means you can answer calls from both lines at any given time.

DSDS: Dual Sim Dual Standby - when one SIM is in use, the other goes into standby mode. This means the inactive SIM will not receive and notify you of any calls or texts.

Can you use two different providers on a dual-SIM smartphone?

Yes, you can absolutely use two different network providers on a dual-SIM smartphone. Although, you will need to make sure that you choose an unlocked dual-SIM smartphone. If your mobile is locked to one network, you can only use dual SIMs from that provider.
