To date, the cost of devices with 2 SIM cards can start from 2000 rubles. and reach values of more than 20,000 rubles. Depending on the price segment, the functionality of the device will also change. However, for the most part, the 2 SIM management system on each phone is the same. The user has the opportunity to use one card, for example, for surfing the Internet, and the second for making calls.
The cost of devices operating on 2 SIM can be much higher than that of similar models with one SIM.
Machine model
In accordance with the selected price segment, determine the brand and model of the device. For example, Samsung was one of the first to offer devices based on 2 SIM. The line of devices manufactured by the company based on a two-SIM radio module is called Duos. At the same time, almost all phones running 2 SIM cards are created on the Android platform. The Galaxy Y Duos and Galaxy Ace Duos are among the most inexpensive and popular Samsung Duos devices.

However, one should pay attention to the brand awareness. For example, Lenovo, Huawei and Oppo make quality devices that deserve the attention of users. However, you shouldn't look away from nameless brands and too low cost.
Devices from little-known Chinese companies have problems with the functioning of the radio module and switching between the modes of two SIM-cards.
Technical requirements
Considering the models, determine the requirements that you put forward to the device. You can purchase a device without a built-in camera for the lowest price, or with a camera, the resolution of which does not exceed 5 megapixels. The most expensive models can be equipped with 13 megapixel cameras. Due to the increased power consumption, a good dual SIM phone should have a battery with a capacity higher than that of a single-SIM counterpart.
