Hello Guys!
I just want to tell all of you is that you can do UPI transaction in Paytm without sim card once you register first time and then remove the sim. After removing the sim you can do transaction normally i don't know why paytm allow this.
Also, read somewhere that u can do it on google pay as well using some notification trick.
Paytm is a joke with verification (personal experience), but a blessing in disguise for many
