I am going overseas this year to either Italy or Greece.
Last year I was in India and my plane was cancelled and I had to buy a new flight. The problem I had was the 2 factor authentication from my bank. The flight cost nearly $1,000 and it was a new provider. The SMS went back to my phone which could not be used as I was only using a local Indian SIM card. My phone does not have dual SIM. Luckily in the end I had a credit card (Latitude) where the 2 factor authentication went to my email, so I was ok. However, I do not have access to that credit card anymore.
I have an samsung A21s
no access to E sim, with this phone
i use Aldi sim and paying $19 per month.
I also tried Macquarie debit card (mastercard) which uses authenticator and then Mastercard wanted SMS. I talked to Macquarie, they said its up to Mastercard if they want authentication. and to contact them. .
I asked the banks to turn off 2FA but they wanted a phone number.
it If this occurs again on this trip, what are my options?
If i get Boost do i then port my number over and then when i get back port it back to Aldi?
your phone can't take esim?
