The way that site is charging you is not legal in Thailand, which is likely why they were flagged.
They are required to clearly state that they are not a government provider and must obtain your explicit consent to their terms, and not straight to payment. They also fail to display any company information, which is a major red flag.
Right now, their site is misleading and lacks the necessary transparency.
Charging for submission services is legal in Thailand if done properly.
In fact, this is clearly acknowledged on the official TDAC website.
We operate the informational website tdac.in.th ( not the one that is mentioned in the announcement ).
Currently, we do not provide any services, and clearly mention the TDAC is FREE.
However, if we choose to offer services in the future, they will be fully transparent, clearly disclosed, and fully compliant with Thai law.
EDIT: We’ve launched a convenient early application service through tdac.in.th. If you prefer to apply in advance, our team can handle the submission for you. This is especially helpful for families or travelers who want to get it done ahead of time without last-minute stress.
There’s no fee for submissions made within the official 72-hour window before your arrival. However, if you'd like us to submit earlier on your behalf, a small $8 service fee applies due to the manual processing required.
Also, just tick a checkbox to include eSIMs for each traveler. Everyone will have internet on arrival, and we’re working to offer the lowest eSIM prices in Thailand.
