All the best and safe travel tomorrow.
To do Verification using aadhaar, you have to get 6 digit OTP sms on your phone. Airtel and Vi sms are reaching abroad [most countries] without any problem, whereas Jio mobile sytem is totally different and you are unlikely to get a normal sms abroad if your aadhaar linked mobile number is a Jio number.
To get Jio SMS outside India, you may need to subscribe to a Jio International roaming package mandatorily.
However, you should be able to verify using Netbanking [provided, AGAIN, you are not getting into Jio SMS OTP issue abroad for Netbanking login]
