I got a 2-month unlimited plan for Thailand, it cost me 90.- euros. Unlimited seems not to be that unlimited, though. Since I am usually somewhere with Wifi here in Thailand, I didn't notice in the beginning how bad it was. Then I went to Indonesia and had a one week plan - which worked fine, I think. But you have to make sure you have the settings right, otherwise you start roaming of your own internet, which might costs you an additional 75.- euros, like it did with me. Then I came back to Thailand and my 90.- day plan didn't work at all. Customer support is a parade of standard answers and AI-generated messages about how they know how frustrating it can be to have no connection....for me it was an absolute waste of money and i don't recommend it for Thailand. I would definitely suggest to get a cheaper 'few-days-plan' first to see how well it works and to check how 'limited' the 'unlimited' package is....
