What is Dual Sim and how does it work?
Dual-SIM is a term to specify whether a device is capable of supporting two SIM cards. There are two major types of dual-SIM phones: Standby and Active.
Dual-SIM Standby (DSS) requires the user to specify which of the two SIMs is able to make and receive calls, while Dual-SIM Active (DSA) enables both cards to receive calls at the same time. This latter feature usually requires an additional transceiver for the secondary SIM card. More recent models feature Dual SIM Dual Standby (DSDS) technology which enables them to have two active SIMs with only one transceiver.
Basically, the latest dual SIM android devices allow you to receive calls in any of the SIM cards without switching anything in the phone. You will only need to set up which SIM card will be used for 2G-3G-4G when inserting a new SIM card, onwards the phone should automatically pick up the calls based on the initial configuration, which will remain until you change any of the SIM cards again.
One device holding 2 different SIMs and identities, that sounds spectacular!
4 reasons to buy Dual-SIM smartphones
It’s all about convenience after all. Look at the scenarios below. If that sounds familiar, you might want to become a Dual-SIM phone user.
1. Benefiting from different plans mobile providers offer.
You might be torn in between 2 sims, where one has a great plan for data transfer, while another one has very cheap rates for calling. With a dual-SIM you simply blend those into one big advantage of not spending extra money.
2. A frequent traveler?
If you are, then consider this. While being in a different country you might want to enjoy the cheap local calling costs alongside with not missing any calls or texts you’d get on your initial number from your home country. Dual-SIM phone is a handy solution. Simply purchase a local sim, plug it in and still keep your first one. Problem solved!
3. Separate personal from business.
There are particular situations when you can’t or don’t want to use the same number for private and business interactions. It leaves you with 2 options: either have two phones or rather get yourself a dual-sim one. This also means you can distinctly split the phone bills.
4. Unstable coverage in your primary sim.
This is a very particular situation which most of us might not be experiencing every day. But in case you do and you want to prevent an emergency case of not being able to call with your primary sim because of poor coverage, dual-sim phone with an option of having a second sim with better coverage really is a solution.
