Hi @Vshen28,
Welcome to TPG Community!
A one time passcode is required to log on to My Account. Hence, you must have your international roaming enabled. If you have TPG mobile and wants to enable it, send us a private message with your TPG mobile number or customer ID. If your mobile is from another provider, please coordinate with them to enable the service feature.
How do I private message (PM) in the community
Regards,
Angeli
