If you have two Sim Slots, try to use the other slot. If still having problems, it means the slot is not picking up the sim card! Check if the sim card is damaged or not!

2nd slot, works perfectly

[Farlow]

ok that's good, it means your sim card is not damaged. Try to use your sim on this slot which works perfectly. do not change it frequently, maybe your other slot is not working or not authorised!!
iss mein phone ka koi kasoor nahi dear :)

Try this Go to settings >connections >Mobile Networks>Network Operators turn off Automatically and one by one manually select your network operator. i hope it will work.
