Hello friends,I hope you all are fine.Today I am here with a new trick.This trick is awesome for those how are using multiple sim cards like me , I have more than 10 sim cards of different operaters. I got confused and so I got a trick to know our own mobile number. Generally people calls from one sim to another phone to know the mobile number but when theirs 0 balance then its very difficult to know it. So I thought to share this trick with you people..
