Modern smartphones are getting thinner and more complex, which often causes difficulties for users when they first set up the device. The question of where to insert the SIM card in the Xiaomi Redmi 9 is one of the most frequent, because the design of the tray here has its own peculiarities.

On the case of the Xiaomi Redmi smartphone, the 9 SIM card tray is located on the top end of the device, a standard location for many modern models of the brand, allowing you to keep the side faces free of unnecessary holes.

Visually, it's a small, oblong hole next to a headphone jack (if you have one in your version) or an infrared port, and that's where the mechanism is, which requires careful handling. Importantly, the tray in Redmi 9 is a combined one, which means you can install two SIM cards or one SIM card and a microSD card.

⚠️ Warning: Never attempt to open the tray with sharp objects such as a knife, needle, or toothpick. Using inappropriate tools can cause the machinery to break down or damage internal components.

To extract the tray, you use a special paper clip that comes with the phone, and if it's lost, you'll get a standard-sized paper clip, and you'll find a small hole next to the tray circuit and you'll press it gently perpendicular to the body.

Before you start a physical installation, you need to prepare the workplace and the media themselves.

Frequent problems and ways to solve them

Despite the simplicity of the procedure, users may encounter a number of problems, one of the most common being when the phone does not see the SIM card, which can be caused by contact oxidation, improper installation or software failure.

If the SIM card is determined but there is no internet connection, check the APN hotspot settings. Often these are set automatically, but sometimes manual settings are required, which can be obtained from the operator's website or support service.

Another problem is that the battery is quickly drained when searching for a network, which happens if the signal in your area is weak and the phone is constantly trying to switch between towers, in which case it is recommended to temporarily switch to 2G/3G mode or use Wi-Fi calling.
