Reversing the implementation of the tray with the SIM card

Inserting the SIM card tray in Xiaomi is as easy as taking it out. First, the SIM card is inserted into the tray in the recess provided for it, and then the card slot/cards are inserted back into the slot from which it was removed. Slide the tray all the way in until you hear a distinctive click.

When inserting the tray in its place, the phone should be placed with the screen facing down, with the SIM card on top. It is not necessary to turn the device upside down after removing the tray so as not to be confused with which side to insert it. The phone must remain switched off when inserting the tray. It is activated only after a click.

Standard recommendations for Android smartphone owners

Xiaomi runs on the Android operating system, and some standard recommendations will be helpful, too:

  • Check the flight mode. when it is enabled, the mobile signal reception is deactivated, Wi-Fi and Bluetooth stop working too. The option is often activated accidentally, so check the settings.
  • Figure out the general settings. card slot may be disabled. Go to the manager and just activate the SIM card. The second card will automatically come into action. the manager will activate both slots. If the card is on, but the phone doesn’t see it, try to send an SMS. The system will ask you to turn the card on by pressing to confirm in the dialog box. The “OK” button and everything will work.
  • Serious damage disables the card. Scratches, fractures, other deformations. a common cause of non-functioning SIM cards. Only replacement will help. To avoid damages in future, don’t take out the card, don’t carry it in a purse,. near keys. The cutting with scissors for size change is not the best idea. Prying a stuck SIM card with a needle or tweezers out of a slot often results in its failure. Phone number stays the same after changing the card. The release of a new one is free or almost free of charge (the price is like buying a new package) depending on the operator.
  • IMEI glitch occurred. an individual code, without which you can not call, write SMS. To check it enter a combination of characters # to display the code. In normal cases phone will show it, in other cases repair is needed. The cause of the damage and how to fix it you will be told at the service.
  • The firmware is glitchy. right away or after an update. Phone still works, but not all functions are available. The device needs to be returned to a restore point, fix bugs in the software part and update. If you don’t know how to do it, contact the service. In practice, Android phones often glitch after an update.
  • Update failed. the problem is not rare, it is easily solved by reflashing through a laptop, computer or by installing the TWRP Recovery patch manufacturer. Reset to factory settings for starters.

Test the contacts of the slot. they can be damaged by water (including rain, not necessarily bathing the phone). Some providers organize special offers, reducing the price of top models and tying them to a particular network. In this case, the phone will see the SIM card of only one operator.

Contacts of the card and the slot are sometimes rusty. cleaning with an eraser will help. Bad contact is caused by a bad grip. try taking the card out and putting it back in. If nothing happens, make an adjustment. There are other reasons, so when nothing helps, contact a service center.
