I will arrive in BKK on November 22nd. Normally I buy a 30 day SIM card from AIS at the airport. This; Because I never stayed longer than 30 days in a row. I then reactivated the card when I return after a month or a few weeks in another country. This time I come with a 6 month visa. So I can (and will) stay 4 months. (interupted halfway by 5 days Kuala lumpur.

Who gives me the best advice for a SIM card with a lot of data for about 4 months or longer?

Here's an "and anything else" query please:

What unlimited data sim card deals do you know of, anything from 2 months to a year? Thanks!
