Menu for working with SIM cards
Having understood the possibility and necessity of receiving calls on two lines, let’s move on to a brief description of the interface for working with SIM cards. Today there are two main suppliers of microprocessors that support dual SIM cards. Among A-brands, solutions from Qualcomm are most often found, among second-tier brands – MediaTek. It so happens that the former often have a longer operating time, while the latter are more productive. Qualcomm processors are valued higher, which is not surprising, given the volume of shipments and the popularity of this developer, while MediaTek became known to a wide range of users only with the massive appearance of Chinese devices on the world market. Despite the fact that until recently few people had heard of this manufacturer, MediaTek solutions have long been used in devices from Motorola, Nokia, LG, and Samsung. Since today’s topic is not processor manufacturers, but dual-SIM smartphones, we will not delve into the history of these companies, and will limit ourselves to the information provided.
As already mentioned, at the moment the user is given a choice of two interfaces for working with SIM cards, and there is not much to choose from, and, in fact, the user asks this question last, if at all. The interface of devices running on Qualcomm processors is more diverse. At the same time, the menu of smartphones on MediaTek is easier to configure, since all the items are in one place.
With the advent of Qualcomm's dual-core Snapdragon S4 family of processors, the balance of power may change somewhat, provided that you are not looking for a smartphone with a high-resolution screen and a camera capable of recording video in HD quality.
Summarizing the above, we note that all smartphones based on MTK processors have the same menu for setting up the operation of SIM cards, while Qualcomm devices are quite different from each other. There are often cases when to select a priority SIM you need to go to the “Calls” menu, to configure messages – “Messages”, and so on. If you don’t have enough knowledge or simply don’t want to understand the intricacies of setting up forwarding, we recommend turning your attention to the Samsung Galaxy S Duos smartphone; as you know, it has the simplest and most intuitive menu.

Thanks to this battery, the smartphone can go without recharging for 2-3 days, if you do not abuse games and web surfing. Poco M3 also supports fast charging, which will allow you to restore battery charge in the shortest possible time.
The Snapdragon 662 processor is responsible for the performance of the smartphone, which ensures fast operation of the operating system and applications.
This smartphone also boasts a large 6.53-inch screen with good color reproduction and a 48-megapixel camera, which, with the support of artificial intelligence and night shooting mode, will allow you to take bright and detailed photographs even in low-light conditions.

Schemes for using smartphones with support for two SIM cards
The most common usage scheme is the first SIM card for Internet access (most often there is a SIM card from the TriMob operator, less often life:, even less often - MTS, Kyivstar), the second SIM is for calls. Another, less popular scheme is to use a dual-SIM smartphone in order not to carry two devices with you. In this case, people most often combine their work and personal lives in one gadget, that is, SIM cards. In addition to saving space, you also no longer need to monitor the charge status of two devices. Surely many of our readers have seen an advertisement for the Samsung Galaxy S Duos smartphone depicting the same man in two roles - in a T-shirt and a business suit, demonstrating the balance between personal and professional aspects of life.
