I think DTAC offers the option, maybe only on their Tourist SIMs, to pay 50 baht for 180 days, or 100 baht for 360 days. They do have another scheme, which costs 2 baht/30 days nut that may require ownership for at least 90 days.

The simplest thing to do would be to use a top-up machine, and add 10 baht (12 baht with the 2 baht fee) to get 30 days. You can repeat this for a max. expiry of 366 days.

Or simply top-up 50 baht in a 7/11 to get another 30 days.

Not sure what happens after the expiry. Expect you get some extensions, like incoming calls only for some grace period?

I searched on Dtac web site and seem come to the following

http://www.dtac.co.th/en/search/pack...0&pmn=NET&pmt=

So it is SIM card (50B) and 1.5GB of data for 30 days for another 199B.


Yes. There are other SIMs as well: Smartphone SIM (49 baht); Happy 4G SIM (69 baht) among others. You can buy any SIM, add value, subscribe to a data plan.


Does anybody know, what would happen after first 30 days? SIM is deactivated? Something else?

No clue. I expect you can continue to receive calls/texts.

If I top up with 250B and use 200B for internet, will be remaining 50B enough to keep the SIM operational?

Yes, but remember VAT (7%), so a 199 baht plan becomes a 214 baht plan.

The DTAC website does not show a shop at HKT. Maybe there is a convenience store or phone shop land-side?
