How to insert a SIM card into a Xiaomi phone: instructions for all models

Inserting a sim card into a Xiaomi smartphone seems like a simple procedure, but in practice users face a lot of nuances, from the wrong size of the nano-SIM to a jammed tray. It is especially difficult for owners of hybrid models, where one slot combines a SIM and a memory card. This article will help avoid the typical mistakes – from damage to contact loss due to improper installation.

We will discuss the process for all types of slots (standard, hybrid, eSIM), specify the features of the popular series β€” Redmi Note 12, POCO X5, Mi 13 β€” and give tips on choosing a SIM card. And if you hold a Xiaomi smartphone for the first time, you will find here the answers to questions about the location of the slot, the necessary tools and even how to remove a stuck tray without damage.

Features of hybrid slots: SIM card vs memory card

  1. Copy data from a memory card to a phone or PC.
  2. Format the card (if it is used as an internal memory).
  3. Remove it and insert a SIM card.
