Why can't I open TDAC on my Samsung Mobile but it works on my PC?

THIM and TDAC notice
Need a clearer THIM and TDAC explanation? Read the THIM guide on thim.in.th.

Have spent 2 days trying to open TDAC on my Samsung Mobile (cookies enabled) no joy, opens fine on my PC and Laptop, any ideas/suggestions. TIA
Answer summary
A user is experiencing difficulties accessing the TDAC website on their Samsung mobile device, although it works fine on their PC. Many comments suggest using a laptop instead, as the TDAC system is noted to have stability issues on mobile devices. Solutions offered include downloading the THIM app for TDAC submissions or attempting access through a different browser (as one user resolved their issue with Firefox). Other responses emphasized relying on laptops for this task, as confirmations are sent via email, which can be accessed on smartphones.

As others have mentioned, if the official TDAC website is not working for you:

******************************


You can try installing the ๐—ง๐—›๐—œ๐—  ๐—ฎ๐—ฝ๐—ฝ, which provides an alternative way to submit your TDAC.

If you are unable to access the official website or install the THIM app for any reason, you can also submit your TDAC through our ๐—”๐—š๐—˜๐—ก๐—ง๐—ฆ ๐—ฝ๐—น๐—ฎ๐˜๐—ณ๐—ผ๐—ฟ๐—บ:

For those who wish to submit earlier, we also offer a manual early submission service for arrivals up to ๐Ÿญ ๐˜†๐—ฒ๐—ฎ๐—ฟ ๐—ถ๐—ป ๐—ฎ๐—ฑ๐˜ƒ๐—ฎ๐—ป๐—ฐ๐—ฒ, with an $๐Ÿด ๐—จ๐—ฆ๐—— ๐—ฒ๐—ฎ๐—ฟ๐—น๐˜† ๐˜€๐˜‚๐—ฏ๐—บ๐—ถ๐˜€๐˜€๐—ถ๐—ผ๐—ป ๐—ณ๐—ฒ๐—ฒ.

There is absolutely ๐—ป๐—ผ ๐—ฟ๐—ฒ๐—พ๐˜‚๐—ถ๐—ฟ๐—ฒ๐—บ๐—ฒ๐—ป๐˜ to use our platform if the official website or THIM app works for you. We simply provide another option for those experiencing difficulties.

Additionally, you can try using a different mobile browser or even a proxy to access the official website.

We regularly receive reports of connectivity issues from travelers in certain countries, particularly China, where access to the official TDAC website can sometimes be unreliable.

Use you laptop then.

If it opens fine on your laptop, why insist on doing it on your phone? They email you a confirmation with your QR code anyway. Surely you can open emails on your phone?

When I tried to use my phone to do in at the Nong Khai crossing the Thai IO told me that the system was unstable when using a phone, as others have said use your laptop and download the pdf to your phone.

Noel Hernberger Thanks .... same as my 90 day system ... sometimes it works sometimes doesnt, and a few times I have emailed them and they sent me a different link that also worked for a while then stopped and was given another link that worked for a while, now I just go to immigration ... the front door/portal always works I've found.

Ian May No need. The app works fine NOW. And the big advantage is you can fill out everything in advance except for the health declaration, save it, and the app notifies you when you enter into the 3-day window before your trip. You declare that youโ€™ve not visited a yellow fever country and the app files your TDAC. The response comes almost immediately. If called on to provide the QR code, itโ€™s in the app.

Bill Peterson I downloaded THIM last night and will register today .... lets hope its better than the website thats been a constant frustration over the years ..... worked great for me when they first brought it out then they did a software update and it never was stable again for me (even my address became just numbers and symbols) ... immigration tried to find the issue but after 4 visits to get it fixed they moved the help desk into the detention area compound and we could no longer access help desk.
