Before the advent of the 7 Best dual SIM phones, you had to manually switch between SIM cards in order to find a contact, make and receive calls, send text messages or send money from another mobile payment service. Alternatively, one could carry around two or more phones, each with its own SIM card
With dual SIM phones, problems with SIM swapping are a thing of the past.
You can have your personal and work numbers on the same phone, get the best calls and data offers from carriers, and even keep your old number without having to transfer it to a new carrier SIM.
What are Dual SIM phones?
Dual SIM is a feature in a mobile phone that allows it to manage two separate network services. This way, you can switch between SIM cards when one operator has service outages.
Dual SIM also helps save money by reducing call costs when calls between users of the same provider cost less.
If you’re an avid traveler, having a dual SIM phone means you can improve your internet connection in certain regions where coverage varies, move between borders and stay connected without huge roaming charges.
The main disadvantage of a dual SIM phone, especially a dual transceiver phone, is that the battery drains faster This is because both transceivers are active using Dual SIM Active (DSA) technology, which allows both SIMs to receive calls at the same time.
Most popular portable devices offer dual standby with hardware auto-switch support. This means that both SIM cards are usually in standby mode when the phone is not in use. But during a call, one SIM card is temporarily disabled for the active one to work.
Older phone models may have a dual-slot SIM tray, but with only one transceiver. In this case, you may have to manually change the SIM cards, since the transceiver is designed to work with one dedicated SIM card
Several phone manufacturers now offer phones with dual SIM cards preinstalled with eSIMs. ESIM is an electronic microchip built into your phone that acts like a SIM card, so you don’t need to change it when you change carrier.
ESIM can be the main number you use, and if you need to get a second SIM, you can add a physical one. However, the installation of eSIM has not yet become widespread due to the inconsistent implementation of this technology by mobile operators and manufacturers.
Best Dual-SIM Phones
Here’s our list of the best dual SIM phones you can get right now. We will continually update this list as new phones are released.
1. Samsung Galaxy S20
As soon as the Samsung Galaxy S10 came out, the S20 was released. As difficult as it is to keep up with the latest Android technology, the S20 has revolutionized the smartphone market.

Some of the striking features include an astounding array of quality cameras, 8K video playback capability, expandable storage up to 1TB via SD card, 120Hz display, water resistance, and wireless charging
It’s nice to know that you can use three SIM cards on one phone, but you won’t be able to use an eSIM and a second SIM at the same time. Also, you need to buy a phone from your mobile operator’s official website in order to use three SIM cards.
If you buy the S20 unlocked, you will not be able to use the triple SIM feature. Instead, you’ll have to use one or two SIM cards and expandable storage.
The iPhone 11 comes with a full range of features right out of the box: a stunning dual-camera system, Apple A13 processor and 64GB of storage. The storage cannot be expanded, but you can still upgrade your iCloud plan when the free 5GB of cloud storage runs out
The phone comes with a pre-installed eSIM tied to the carrier of your choice, but you can add your physical SIM card as the primary number you use. You can also buy an unlocked iPhone 11 and set up an eSIM on your mobile carrier.
3. OnePlus 8

4. Samsung Galaxy A71

Other than that, it is also powered by a Snapdragon 730 processor, a large 4500mAh battery, fast charging, 128GB storage, and 6GB RAM.
Galaxy A71 supports dual SIM even when unlocked. If you buy a phone with an eSIM, you get a full triple SIM support guarantee. The phone’s SIM tray supports two nano-SIM cards or one nano-SIM card, and expandable microSD storage up to 1TB.

With a small form factor equivalent to an iPhone 7 or 8 and a tiny display, the 2020 iPhone SE is no doubt a wolf in sheep’s clothing.
