Replacement SIM-The card or its extraction for transfer to another device is a routine operation that can turn into a headache if you do not know the nuances of the Xiaomi Redmi 6 design. This model, released in 2018, is still popular due to the balance of price and functionality, but its hybrid tray (support 2 Nano-SIM) + microSD) is a frequent question for users, and unlike flagships with retractable mechanisms, it's simpler -- but the risk of damaging contacts with careless extraction is higher.
Many owners face problems: the tray does not come out the first time, the SIM gets stuck inside, or after extraction, the network ceases to be defined. SIM-The card (including the emergency version without a paper clip), analyze common errors and give recommendations for the care of the slot, and if you plan to replace the SIM with a new one, there is a checklist at the end to check compatibility.

- Is the service "Mobile Internet" activated - when changing the SIM card, it can turn off.
- Are contacts retained on SIM-card (if yes, export it to your phone's memory).
Method 1: Standard extraction by means of a paper clip

Do not use force if the tray does not yield.-->
β οΈ Attention: If the tray does not come out after 2-3 attempts, do not push harder, it can break the mechanism. Try to slightly sway the paperclip left-right or change the angle of pressing. In extreme cases, move to method 3.
When the tray is out, carefully take it out and remove it. SIM-Notice the markings inside the tray:

5. Common Mistakes and How to Avoid Them
Even with this simple procedure, users often make mistakes that lead to breakdowns, and here are the most common ones and ways to prevent them:
Mistake 1: Using the wrong tools
Many people try to open the tray with a knife, scissors or even keys, which leads to:
- π§ Scratches on the body around the hole.
- π₯ Breakdown of the spring mechanism inside.

- πΆ Lack of network (the phone does not see the SIM).
- π Fast battery discharge (phone constantly looking for network).
- π₯ Overheating of the communication module (due to short circuit of contacts).
Solution: Always make sure that the bevelled angle of the SIM coincides with the angle on the tray.
1. correct installation of the SIM (contacts should be at the bottom).
2. the purity of contacts (wipe them with a stripe or alcohol).
3. the SIM's performance on another phone.
