SIM-map: 🛠️ Use a paper clip to extract the tray (on Xiaomi 14 the tray is on the right). 🔍 Check the contacts on the map and on the phone - they should be clean, without scratching or oxidizing. wipe them with a soft cloth (do not use alcohol!). 📏 Make sure the card is properly cropped: nano-SIM should fit tightly into the tray without backlash.
2. Try another one. SIM-map: 🆔 Insert a SIM from another operator (e.g. MTS instead of Tele2). If the network appears, there is a problem in your card (possibly blocked by the operator). 📱 Check out the same one. SIM-If there is no network, call the operator (support numbers: MTS - 0890, Beeline - 0611, MegaFon - 0500, Tele2 - 611).
