“I have paid $1000 for something called an eSIM because I clicked in an ad without realising. How do I set it up on my Nokia and will it work in Thailand?”
I'm insinuating that Thai bank ATM fees for foreign cards (@$6.50 per transaction) are the highest I have encountered anywhere. But there's little escape (over-the-counter cash withdrawals charge about the same) unless you have a local bank card - see Q1!
