Best Dual SIM Smartphones in 2020

It would seem not so long ago, when mobile phones entered our lives, we could not imagine that the phone would not have buttons, that it would be possible to use it not only to make calls and send short text messages. Now we cannot imagine life without this device. With its help, we not only keep in touch, but also have fun, learn news and useful information, thanks to the presence of the Internet. And at the moment there are quite a few operators, each of which has different tariff plans. One is designed for inexpensive calls, the other for profitable Internet, and the third has full unlimited and one-time monthly fee. And in this case, it is not always possible to make a choice profitably in your favor. But the smartphone makers took everything into account and made devices with two SIM cards.

Types of smartphones

There are a lot of criteria by which these devices can be divided, but the division into types in this case will have a very fuzzy border. Therefore, let's take a look at the types of smartphones with different operating systems.

The most common operating system is Android. Since Google has owned this operating system since 2005, when using an Android phone, it automatically gets access to all the company's capabilities. When you turn on the phone for the first time, you will be required to enter a Google login, if any, or register. After that, there will be full access to maps, documents and other services, and most importantly, access to "Google Play" will be opened, where the user can download a free or paid application. Today there are more than 700 thousand applications, and the number of downloads exceeds 25 billion.

Another popular operating system is iOS, which was previously called iPhone OS. iOS is developed and published by the well-known American company "Apple". This OS first appeared in 2007, and is only suitable for iPhone and iPod. There are over 1.5 million applications for iOS devices, and their downloads worldwide have reached over 100 billion.

Popular manufacturers

Today there are many companies involved in the production of smartphones. Therefore, let's look at popular and well-known brands that have proven themselves in the market.

Apple

The company was founded in the 1970s in California. It was founded by Steve Jobs, Steven Wozniak and Ronald Wayne. It all started in the garage of Jobs' adoptive parents, and gradually grew into a serious business. Then the name of the company arose - "Apple". This name does not have any hidden meaning, it was chosen in order to occupy an earlier position in the telephone directory than that of the main competitor.

It is worth noting that moment in the history of the company when Steve left it. It was in the mid-80s. After that, the business of the company began to decline, and by the end of the 90s "Apple" almost went bankrupt due to its debts.But then a turning point occurs, Mr. Jobs returns to the company, and things immediately start to go up. The beginning of the 2000s was the opening of new heights for the company. Indeed, during this period, such popular gadgets as the iPhone and iPod were released, as well as the iTunes Store was opened.

So, gaining popularity, the "apple" company in 2011 became one of the most expensive companies in the world.

Today it is considered prestigious to have products with the apple logo, even if there are budget options that are not inferior in technical characteristics.

Samsung

This company from South Korea was founded back in 1938, and its name means three stars.

The initial activities of the company were not related to electronics. The company took this direction after the new reforms that were created during the end of the Korean War. Thus, in 1969, Samsung began to produce black and white TVs. Still, the company was not doing well, so changes in the company's policy followed and a new logo appeared.

Now the company has undoubted success on the market. Samsung has more than 60 offices located around the world, and the number of employees is about 500,000.

Huawei

This Chinese company was founded in 1987. Its main activity extends to the creation of telecommunication networks and the creation of mobile devices under its own name.

In 2015, this company took the third place in the world for the production of smart phones, and in 2018, Huawei surpassed the American giant and took the second place in the world. And in the Russian market in 2018 it took first place in sales of mobile devices.

In 2019, together with a Korean company, smart glasses were presented, where the right will have a battery, speakers, a microphone and an antenna. Also this year, the brand released a smartphone with 5G support and its own operating system, called Harmony OS.

It is also worth noting that the company has repeatedly been accused of unfair development and espionage. But Huawei has shifted all responsibility to employees.

Xiaomi

This Chinese corporation was founded in 2010. Today it ranks 4th in the world for the production of smart phones. Xiaomi released its first smartphone in 2011, and the next year a new model with improved characteristics was released. Every year the products of this manufacturer went up, and in 2015 their first camera capable of shooting in a hostile environment was presented. And a year later, a new smart bike was presented to the world. In 2019, in addition to new smartphones with high performance, a smart blanket was created that can adjust to body temperature.

Today the main activity of Xiaomi is aimed at developing smartphones. There are several lines that have a different price category and are intended for a specific target audience, there are also tablets, headphones and fitness bracelets in production.

How to choose a smartphone

Today the market for mobile devices is so wide that it is practically impossible to make a choice in favor of a particular model. Therefore, first of all, decide on your budget, and start considering options from this price category.

Pay attention to the body material. Many models now have a beautiful and stylish glass case. On such panels, fingerprints will immediately be visible, and mechanical damage to it is quite simple. There are also plastic options. Such models do not look very solid, but they are more resistant to mechanical stress. Although today there is a large selection of protective cases with beautiful designs that will help keep the case intact.

Battery capacity is responsible for battery life. Therefore, based on your needs, choose the model that best suits this parameter. Also, now most options have a quick charge function. That in a short time allows you to completely restore the battery charge.

Also, do not forget about the screen diagonal.If you mostly have to work with one hand, then do not choose a model with a large diagonal. It will be very inconvenient to use it. But if you like to read books using your smartphone or work with text documents, then the small display size will be inconvenient. In addition, with a screen with a large diagonal, it will be convenient to watch videos or play, but do not forget about where you will carry the device. For example, a smartphone that is too large may not fit in your pocket.

Display resolution plays an important role in the price of the device. Nowadays, models with a resolution of 4K are gaining popularity. They have a very high pixel density per inch. But this will be noticeable only if you look at the screen almost closely. Since we usually use the device at a distance of about 30 cm from the eyes, the difference will be very imperceptible to us.

Also, camera performance is not the least important. But here you shouldn't pay attention to the number of megapixels indicated by the manufacturer. Since the result will depend not only on this indicator. In this case, it is better to refer to reviews on the Internet and compare the quality of the images.

Depending on the purpose for which the purchase of this gadget is carried out, pay attention to the amount of built-in memory and the maximum allowable amount of built-in memory card.

There are also models with one or two SIM-cards. If it is more convenient for you to use two different operators, then the second option will be very useful. But some models combine a slot for an additional SIM card with space for a flash card. In this case, you should take a model with a large built-in memory or refuse the second operator.
