You may or may not be familiar with dual SIM phones, however, since they can be a great solution and a much better alternative in comparison with actually having two separate devices, we decided to present you with detailed information regarding dual SIM phones.
If you are buying a new phone you may want to consider going with a dual SIM phone. Luckily there are many amazing phones on the market that offer that option.
Herein you will learn all about why you’d need dual SIM phones in the first place, how they work, and we will take a closer look at 12 best dual SIM phones currently available on the market. Moreover, we will also provide you with a dual SIM phone buyer’s guide that will help you choose the best phone for you even if you decide to stray away from the list of phones below.
We will end up the article by answering some of the most common questions regarding dual SIM phones.
Are you ready? Let’s dig in.
Why Would You Need A Dual Sim Phone?
If you already know a thing or two about dual SIM phones, then you have some ideas, why you might need one. However, if you are just getting to know about dual SIM cards, this section will help you realize how useful can they be.
Here is a list of main reasons for getting a dual SIM phone:
- You need two separate numbers (two lines) but do not want to deal with two phones.
- You are traveling a lot and want to have one USA based SIM and others for foreign countries.
- While you move around the States a lot and wont to get the best coverage in all areas by combining the services of two different carriers in a single device.
- You have a separate home and work mobile numbers and would like to use a single device.
- You have one SIM card that offers you a great data deal and the other for calls.
We’ve listed the most common reason why people need dual SIM phones. To sum things up, dual SIM phones let you use two lines, two separate SIM cards that can be from the same or different carriers in a single device. If that is something you’d be interested in, then you absolutely need to consider dual SIM phones during your next phone upgrade.
How Do Dual Sim Phones Work?
Dual SIM phones work no differently than any other SIM-based phones, which are all phones that are operable on 4G LTE networks. There is even a high chance that you already own a dual SIM phone without even knowing.
Dual SIM phones need only one SIM card to operate. In the case of using dual SIM phones with only one SI; card, their operation is no different than the operation of single SIM phones. The things can be slightly different when you decide to use the second SIM at the time.
The SIM card slot on dual SIM phones has two compartments. Normally they are numbers with 1 and 2 and represent SIM card 1 and SIM card 2. If your SIM card has a PIN number, you will have to enter it when turning on the phone. Pay attention to which SIM’s PIN is your phone asking.
NOTE: Our advice to make things more practical is to set the same PIN numbers on both SIM cards, just to avoid confusion and potentially locking your SIM card.
Once your phone is turned one, you get to choose all the details on which SIM card should be primarily used for certain actions (outgoing call, text messages, data transfer). You can also set things in a way for your phone to always ask you which SIM you want to use when sending a text or initiating a call. Moreover, you get to determine, which SIM card is your primary one. The ingoing messages and incoming calls are obviously coming in for both lines (both numbers at the same time). The exact settings and the scope of them vary from phone to phone.
The use of dual SIM phones sure requires some initial getting used to, however, once you are all caught up with the game, you can benefit from this option greatly.
NOTE: Older models were dual SIM standby (DSS), while all newer models are dual SIM active (DSA), which is way more practical. For more information on DSS and DSA see the FAQ section below.

What to Consider Before Buying Dual SIM Phones
This section is here to serve you as a buyer’s guide when deciding on which dual SIM phone to purchase. The points that you must consider are no different than the ones when buying a single SIM phone. However, you should keep in mind that newer dual SIM phones offer more advanced dual SIM related settings that make it possible to perfectly meet your needs, while older dual SIM phones come with rather limited dual SIM settings.
Operating System and Processor
There new smartphones coming to the market on a monthly or even weekly basis and generally each next model comes with a better, faster, more capable processor and updated version of operating systems. If you want to be able to perform the most advanced tasks, multitasking and play ultra-high-resolution games smoothly, you want to go with the latest models. However, if you want your dual SIM phone mostly for basic stuff, you can go with older models or even make things super simple by choosing a dual SIM flip phone.
When it comes to the operating system, you basically have two options – Apple’s iOS or Google’s Android. These are very different and it is mostly up to you which you prefer. It is impossible to say which one is better. Apple’s system is way more closed and thus tends to offer more security, while Android offers way better compatibility with various devices.
NOTE: There is one problem; Apple has not offered its dual SIM phones in the US so far. They do offer an option of internal eSIM, which lets you have one regular SIM and another eSIM carrier at the time.
The latest phone all come with at 32GB of storage room and mostly (at least Android models) let you expand your storage with the use of external microSD card. If you plan on using your phone to take a lot of high-quality photos and HD or even 4K resolution videos, you will need large storage. However, if you plan to store only music, 32GB is usually more than enough.
Display resolutions on the latest phones are all way beyond what the human eye can notice. The more important thing is if they perform well in sunlight so that you can see the display even when the sun is shining on to it. Makes sure display offers enough brightness and ability to turn on night-mode to protect your eyes and brain in the evening.
If you plan on taking photos and videos just to view them on your phone, then most phones will fully cover your needs. However, if you are enthusiast photographer or even a semi-professional, who wants to use his phone for certain shots and have those photos printed out or used on large screens, then you definitely want to aim for phones that are no more than 1-2 years old or even better go with the latest models. Samsung, iPhone, and Huawei have been brands that have lately been delivering phones with the best camera performances.
Compatibility with Carrier
In order to have the ability to use your dual SIM phones with two different carriers or be able to use any foreign SIM card, we advise you to focus on getting dual SIM phones unlocked. You can initially buy dual SIM phones unlocked (t.i.: able to operate on various carriers’ networks) or request your carrier to unlock your phone (this normally comes with some prerequisites that must be met).
As you probably know, 5G is out and already operations. There are only hand full of phones that offer 5G services at the moment but most new phones that will come to the market will have this function. 4G LTE is still what most phones operate on. Phones that are limited to 3G (normally made before 2015), are not accepted by most carriers (only existing clients can use them) as the 3G network is determined to be put out of operation in 2021.
The era when phones were used only for basic stuff and were as such able to last for days is the thing of the past. These days the majority of people use their phones a lot, besides, with large displays, which drain up the battery, we are mostly pleased if the phone can carry us through the day on a single charge. To be honest, it doesn’t make a huge difference to charge your phone every night or every second night, right?
As such, make sure that your phone will be able to carry you for the whole day (in case of high-demanding games, this won’t be possible).
Many phones come with some advanced awesome speakers, however, most users don’t pay too much attention to this as the majority uses headphones or earbuds with their phones. If you have a hearing disability or plan on using your phone in a loud environment make sure its volume is loud enough for your needs.
If you plan on charging your phone mostly during the night, this isn’t too important. Moreover, things can be managed with the use of power banks, which are highly accessible these days. However, if you want your phone to charge 50% or even up to 75% in 30 min, chose a phone that comes with fast charging option (this will also require a specific kind of charger).
The budget is probably the only reason why we all don’t have the latest phones, right? The phone is an important thing these days, however, having the latest smartphone is not. So make sure to consider your budget and spend on your phone only as much as you can spare.
