Types of Dual SIM

There are three types of dual sim phones: passive mode, way in standby y active mode.

Passive dual-SIM

Passives are the most basic. They allow you to have two cards in a smartphone, but only one of them will be operational. Thus, you will be able to change from one line to another, without having to turn off the phone, or insert and remove your card. But you will not be able to receive calls at the same time, but you will have to choose the one that is active and it will be the one that can receive calls and use mobile data.

Dual SIM standby

on mobile dual SIM standby , we can have both active cards, so that we can receive calls from each of them. But the moment we receive a call in one of them, the other will be suspended. Thus, if a call arrives while we are talking to another person, we will lose it.

Dual SIM active

Finally, the active Dual SIM mode will allow you to have two lines at the same time with all the possibilities, that is, being able to receive calls at the same time on the different lines. With this you can choose which of these calls has priority. It is the most comfortable and useful option.

Why buy a mobile with Dual SIM

If you have a personal and a professional line or if you spend a lot of time abroad, the advantages of dual sim phones are obvious. And it is that you can use two different lines in the easiest and most comfortable way.

The main disadvantage that we find is that many brands do not offer this feature in their star smartphones. Therefore, it is easy that in exchange for the dual SIM, you have to give up other benefits.

We also have the problem that, even if we have two active lines, we can only use one of them to send and receive WhatsApp. Therefore, we will have to leave one of them only for calls and SMS.

But, in general, the advantages of using a mobile phone with Dual SIM are greater than its drawbacks, so if you are a regular user of two different mobile lines, it will be recommended that you look for this feature when changing for a new smartphone.
