SIM Tray in Realme 3
A SIM tray or SIM Card Tray is a small rectangular slot on the top left side of your Realme smartphone. It is used to hold your SIM card and memory card securely inside your phone.
We used to open the phone back cover and remove the phone battery before replacing the SIM cards and memory cards in older phones.
But the SIM card tray has made it very easy to replace, add and remove SIM card and memory card without opening the back cover of the phones.
Due to this, we find the non-removable batteries in our smartphones resulting in long battery life and compact devices.

Realme 3 SIM Tray
Realme 3 also has a SIM card tray on the left side of the smartphone. The Realme 3 SIM tray is located on the top half left of the smartphone. You can easily find it when you tilt your smartphone towards the right side.
You can see a pinhole with a rectangular part nearby, and this is your SIM tray. You can eject your SIM card using a SIM ejector tool.
SIM ejector tool comes with all Realme smartphones out of the box. SIM ejector tool is a small metal pin but it is a very important tool that is used to eject the SIM tray.
Realme 3 smartphone comes with a three-card slot including Two SIM slots and a dedicated microSD slot in the SIM tray.
So you can insert three cards including two SIM cards and one microSD card at the same time. Realme 3 is a dual SIM smartphone and both the SIM cards are dual standby and can work together and receive calls simultaneously.
You can even make calls using a SIM and access the internet from another SIM in your Realme 3 simultaneously.
Realme 3 supports a dedicated microSD card, so you can increase its internal storage up to 256GB by using a 256GB or less memory card.
We always recommend you buy a good quality microSD card to avoid data loss and to protect your data from getting corrupted in your memory card.
Low-quality memory cards can’t support recording of high-quality videos like 1080p, 2k, 4k or higher. They also don’t support capturing photos in FHD and your photos will not open properly after some.
I experienced this thing personally in my smartphone and most of the data saved in my phone was corrupt.
