All you need to know about dual-SIM phones.
Dual-SIM phones came into the global spotlight after Apple added dual SIM support to its iPhone XS, XS Max, XR and later models. However, for over 18 years before that, they had already been widely popular. Especially in countries across Southeast Asia and the Indian subcontinent. Wondering why? Read on to find out what is the point of a dual-SIM phone and how it can make your life better.
What is dual SIM?
It is exactly what it sounds like – a phone that supports two SIM cards at the same time. Depending on the phone model, these can be two physical SIM cards, two eSIM cards, or a combination of both. The two SIM cards can belong to different networks or even countries, making you reachable wherever you are.
How does dual SIM work?
There are two main types of dual SIM phones – dual-standby SIM and dual-active SIM. Dual-standby SIM phones allow active use of one SIM at a time. So, if you’re on a call on one of your SIM cards, you can’t be reached on the other one. Most dual SIM phones out there are of this type. Dual-active SIM phones have two antennas – one for each SIM – allowing you to receive calls on both numbers at the same time. These types of phones are very rare.
How can a dual-SIM phone make your life better
1.A dual-SIM phone helps you separate work from private calls.
2. A dual-SIM phone makes international travel easy.
If you often travel internationally or have family living abroad, you know how expensive making and receiving calls can be. A dual SIM can help. Next to the SIM card you use on a daily basis within the USA, you can get a prepaid SIM card with an International Plan that includes unlimited calls or texts to several countries. Examples of such plans are the Lycamobile International Plan and the Simple Mobile Plan.
Special perks for Mexicans in the US
If you’re a Mexican living in the US, a dual-SIM phone means you can use both your Mexican SIM and an American SIM. You could keep both and simply recharge your Mexican phone online whenever you need more call credit or data to stay in touch with your family. Keep in mind that having two SIM cards from different operators or countries requires an unlocked dual-SIM phone. Otherwise, the mobile operator who sells you the phone might limit you to using two SIM cards from their network.
