Thank you for all your responses. They are very helpful! Please allow me a couple more questions:

I see that AIS has a "Working from Home" package with 50 GBytes for 500 Baht. However, the page doesn't say "order" or "buy", it says "Apply".
https://www.ais.th/workfromhome/en/i...n-workfromhome
Is that offer available to anyone, or are there specific requirements?

What is the bandwidth for that offer?

Are there any (other) data packages for more than 10 Mbit/s?

Thank you!
