What is a dual SIM?
Dual SIM mobile phones allow you to use two different numbers with the same device. Dual SIM smartphones have two slots to insert two SIM cards that can be used in parallel.
These types of devices are very useful in your working life since you can have your company phone and your personal phone in the same terminal. In addition, you can use a dual SIM phone to save on your rate, combining a data rate with a call rate.
Dual SIM smartphones are terminals like the others, but with a small peculiarity. They allow us to have more than one card with different lines. Both active and functional lines. Or what comes to the same thing, two phone numbers without having to carry two mobiles in your pocket.
Dual SIM types
Currently, you have several types of dual SIM with which you can use a single terminal for two phone numbers. This point is essential if you want to buy a mobile phone that supports dual SIM, since the way in which you will be able to communicate with one or the other will be completely different. To know the type of dual SIM you want, the first thing you will have to think about is your needs, and from there, look for the type of dual card that will best meet your needs.
Specifically, there are several types of dual SIM terminals:
- Passive dual SIM: In these mobiles, we can have a dual SIM inserted but only one will be active. In other words, if they call our second card, it will not work. In this type of phone, we can use both lines, but never at the same time.
- Dual Standby: With dual standby SIMs, both cards are left on standby. In this way, if one of the lines receives a call, the other is suspended.
- Dual Call or active dual SIM: They are one of the best options if we frequently need to use both lines. In this case, the terminal allows us to use both cards at the same time. However, this results in higher battery consumption.
Advantages of using dual SIM
As we have already told you before, having a dual SIM mobile device will allow you to carry two different phone numbers on a single mobile. Thanks to the dual SIM you will be able to concentrate both your business telephone and your personal telephone in the same terminal without having to charge and worry about two mobiles.
The million-dollar advantage, and the one that everyone wonders about, is whether WhatsApp can be used on a dual SIM mobile. And the answer itself, but you can only use the application in a single line. If you want to use two WhatsApp accounts, one for each line, you will have to resort to unorthodox methods, such as an application to clone apps.
Something that you may not have realized is that the dual SIM is perfect for your trips abroad, outside the EU, and that is that by being able to have a dual slot on your mobile with a dual SIM you can buy a prepaid card in the country you visit. With this advantage, you will be able to save a lot of money and you will be able to make calls and be connected to the internet whenever you want without worrying about your bill.
Saving will cost you less if you have a dual SIM because you can contract two different rates for each phone number. If you want to contract, for example, a data-only rate on one line, on the other you will be able to contract minutes to be able to call at no cost.
Best dual SIM phones
As you may have seen if you have tried phones from different manufacturers, their brand has a great influence on the quality-price ratio of all of them. Not all terminals work or respond in the same way. And the same goes for phones that use a simultaneous dual SIM.
Since at the moment it is not possible to have two numbers on one SIM, the solution provided by a dual SIM phone is very good. The only drawback is that premium range smartphones do not usually incorporate the possibility of inserting a dual SIM in the same terminal.
This does not mean that today we cannot find mobiles that will not leave us lying at lower prices than the S10 or the iPhone on duty. In this post, you will find some of the best smartphones of different ranges.

The best rates to save on the second line of your Dual SIM phone
One of the main advantages of these terminals, beyond the possibility of having a dual SIM, is that we can save with a rate without fees such as the zero rate of República Móvil. There are many rates that can be used as a second line, although the ones that allow us to save the most are the free ones.
In Simyo we have the option of the Rate Without Fees whose monthly amount will be €0 if we do not spend anything during that month. If we need to make calls, they will charge us €0.06 per minute plus €0.18 for call establishment and €0.4 for each megabyte we download.
At Republica Movil, we have the Zero Rate, whose characteristics are very similar. With a small nuance, the first ten minutes of conversation will be free and then we will pay them €0.01/min with a call establishment of 20 cents. For each mega that we download while browsing the internet, we will have to pay 0.02 cents.
Perhaps these rates do not adapt to what you are really looking for and fall a bit short. Take a look at the ones we have selected for you. These have more megabytes but you will have to pay attention to the minutes you have been talking on the phone because some offer you a limited number.
Choose a good rate for your Dual SIM smartphone
If you have a personal number and a company number, you no longer have to carry two mobile phones, with a Dual SIM smartphone you will have both numbers on the same device, although you must bear in mind that both will not work at the same time, if not you will have to indicate which of the two you want to make calls or surf the net with. For this reason, it is important that you choose the rates for talking and surfing wisely. A very complete rate with gigabytes and unlimited calls for the professional part will avoid problems, while for your personal life you may not need so much. Analyze your consumption and choose well!
