A SIM card is a small card with a chip that allows telephone companies to identify users correctly. With this SIM card, each user is associated with a telephone number and a series of services are attributed to him according to the rates that we have contracted. There are different sizes of cards that have been reducing their size as mobile phones and other digital devices have evolved..
Thanks to the SIM card we can perform tasks associated with our provider such as making calls, or using the Internet under mobile data when we do not have a WiFi connection. Inside this SIM we can also store contacts and that is why it is important that we know how to put it correctly in our Samsung Galaxy S21, S21 Plus and S21 Ultra.

How to put SIM card in Samsung Galaxy S21, S21 Plus and S21 Ultra
What we will need to be able to do this process is the following:
- Mobile Samsung Galaxy S21 Series
- Original skewer or similar
Now we will notice that at the bottom of our Samsung we have a tray with a hole.
To open it we are going to use the standard skewer and click on the hole to open it.
We extract the phone tray.
Now we will place the SIM card in the correct position in SIM 1 or SIM 2 according to the drawing of the tray.
Insert the tray back into the phone in the correct position.
Now our Samsung will recognize the SIM card and ask us for the associated PIN.
