Two-sim mode allows you to separate work and personal contacts without having to carry a second phone. In this article, we will discuss in detail the installation process, the types of cards supported, and how to solve common network definition problems.
Before you start manipulating, make sure the device is turned off. Although modern Hot-Swap standards theoretically allow you to change the SIM cards on the phone on, to correctly register with the network and prevent software failures, it is better to perform this procedure on the device off, which ensures that the system correctly reads the profile data on the first start.

Another problem is that the nets fall out after the case is installed. Some thick case protection can slightly press on the tray, disrupting contact. If you notice that the network disappears exactly after you put on the protection, try replacing the accessory with a thinner one or one that has a cutout under the SIM tray.
💡
If the phone does not see the network for a long time after installing a new SIM card, the first thing to do is check whether the card itself is activated from the operator. New SIMs may require activation through a call to support or through your personal account.
In rare cases, the problem is a software failure of the communication module, which helps to reboot the device or switch flight mode, if nothing helps, perhaps the tray itself or the antenna module is damaged, which requires contacting the service center.
