@mariyashamim  Have you tried turning your phone off and then back on again?

And to add to what @Bambino says above, make sure the old SIM is not active, say in another phone

If the old SIM is in use in another phone, putting that phone into Flight mode should be enough, until your new SIM becomes active. 

and Good luck, @mariyashamim.
