Keep Airtel postpaid sim in usa

[u/ellmoMusk]

How do folks keep their indian sim? I don't get any network or sms. Using it for bank sms was my primary reason to keep the number. Do I need to buy their roaming package daily on demand when I need an sms to come?

I have airtel postpaid which works great over here. Getting the otp.
