    Redmi Note 4 is one of the best phones in the market and it won't be wrong to say that it has captured the market as of now.

    • 2.You must have got one SIM ejection pin with the mobile. 
    • 3.Use that and insert it into the hole on the left side. 
    • 4.As soon as you press it a little towards inside, the tray shall come out. 
    • 5. Pull it out and put the Nano/Micro SIM in it. 
    • 6. Push back the tray in the same orientation and you are done.!
