Nowadays, people’s lives have completely transformed due to technological advancements. The world of smartphones has definitely evolved too. It’s no doubt that smartphones have become an inevitable part of our lives. With the development of dual SIM phones, built with an additional SIM card slot, people can now manage personal as well as business calls from a single phone. Gone are the days where people have to carry two mobile phones or switch SIM cards so they can separate their personal and business contacts. This is one of the primary benefits of having a dual SIM phone; you can have one mobile number for family and friends, and another one for work colleagues.

 

What Is a Dual SIM Phone?

Dual-SIM phones allow the use and insertion of two SIM cards on a single smartphone or device. This is different from a single SIM phone, which only allows one SIM card for use. Most dual SIM phones have active dual SIM capability. A dual SIM phone can support two active SIMs at the same time without the need for removing and switching SIMs to change your mobile number. As a result, you can receive/send messages and calls on both lines. You can also choose which SIM card can be your voice call card or primary mobile data/network. 

 

Why Are Dual SIM Phones Good?

For some individuals, purchasing dual SIM card phones can be beneficial. It greatly benefits entrepreneurs who tend to have one mobile number for their business or work and another one for personal contacts. A businessman or businesswoman can either have two different mobile phones, one for personal use while one for business networks. With a dual SIM phone, you can have both numbers active and ready for use anytime. Carrying one mobile phone is more convenient, safer, and more comfortable than having two mobile phones.

Dual-SIM phones that are unlocked or aren’t tied to specific networks let users register or activate any mobile carrier they like. That said, it’s one of the excellent options for frequent travelers. You can effectively use a dual SIM smartphone for activating a local SIM when you travel to a foreign country without worrying about unlocking your smartphone or purchasing a new phone for traveling.

Another advantage of a dual SIM phone is maximizing your usage for phone calls, texts, and other purposes such as mobile data. Some network service providers have great mobile data plans but pricey voice plans and vice versa. With a dual SIM phone, you can combine conveniently two different phone plans from two different network providers and still get a cheaper monthly bill for data as well as calling and messaging.

 

How Does a Dual SIM Phone Work?

When you’ve decided to buy a dual SIM mobile phone, you should know how it works as well as its different types of implementation.

 

Here are the different implementations of a dual SIM phone and how they work:

 

Dual SIM (Dual Active)

This type of Dual-SIM phone lets you call someone from both of the SIM cards activated on your mobile phone. It can also receive calls on either of the two SIM cards all at once. This implementation has both SIM cards active and when you are calling someone from one of these networks, the other SIM still works and can make phone calls, receive texts, or use mobile data.

 

Dual SIM (Passive)

A Dual-SIM passive phone can support two different SIM cards; however, only one of them can be active at any given time. That said, one SIM card is not reachable or won’t work since the other SIM is activated. If you want to use the other SIM, you need to activate it manually.

 

Dual SIM (Dual Standby)

This implementation is a combination of Dual Active and Dual Passive. It allows your smartphone to have two active SIM cards, and they utilize only one radio transceiver. As a result, they are both active only for as long as they’re not in use; hence, the name itself. As long as both SIM cards are in Standby mode, you can text or call someone on any of the SIM cards.
