Uploaded the instruction booklet all in thai hope someone could tell me what they mean especially the *101# codes

I just try to wade through the scattered infos on the DTAC websites.

Here is a site that explains some *104 package applications in English:

https://www.dtac.co.th/en/prepaid/products/happy-unlimited-internet-package.html

As usual at DTAC you append another "*9" to get response in English.

If you really want translations the thread would be better in the Thai language subforum.

Some hints on *101 and *104:

*151# is to check whether SIM is registered with a user name (ID card, passport).

Should be quite obsolete nowadays.

Just use the app instead.

Just use the app instead.

I am not a DTAC user.

What app is that?

To the OP:

just do a Google site search and you will find most if not all of the codes.

Example string:

*103*215*9 site:dtac.co.th

(*9 append to get English language result)

Good luck in fighting through the jungle of tariffs

The dtac app.

To guys that told me to use the app. Thanks it's very easy to use and they have many promotions very good prices for tourists.

And there is an AIS app also.

Will install and check.

Is there anything similar for truemove h? Their website promotion page is clear as mud, mobile unfriendly and still promoting prepaid packages that expired last December.
