Cancel True/DTAC: Close Your Thai Line and Package Renewal the Official Way
Independent guide — no official affiliation with true.th.
Short answer
At True you can cancel an auto-renewing package via TrueID App > Package > Cancel or the *9000 USSD code; closing the number itself requires calling 1240 or visiting a True Shop with ID. Prepaid lines have no contract — numbers unused for 60 days drop.

Step-by-step fix
ADIM 01
Sign in to TrueID App
Open TrueID App and sign in with your True number. Switch to the 'แพ็กเกจ' (Package) section in the bottom menu.
ADIM 02
Cancel the active package
Open the active package details and tap 'ยกเลิก' (Cancel). Confirm on the next screen; auto-renewal stops immediately.
ADIM 03
Quick route via USSD
Dial *9000 and call; choose package management in the menu and confirm the cancellation step. The confirmation SMS is in Thai — look for 'ยกเลิกสำเร็จ' (cancelled successfully).
ADIM 04
Close the number completely
Call 1240 (True customer service) and say 'ต้องการยกเลิกเบอร์', or visit a True Shop with your passport/ID. On postpaid the remaining period bill is processed; take the request reference in writing.
ADIM 05
If you want to port the number
Start a port-in request with the new operator; when the Thai MNP completes the True line closes automatically — no separate cancellation needed.
02 — Frequently asked questions
Frequently asked questions
Does package cancellation refund anything?
No — the remaining period of a cancelled package is not refunded; only the renewal stops. If you bought the wrong package, call 1240 and dispute within 24 hours.
When does a prepaid line close by itself?
60 days after the last recharge the number drops; a minimal top-up inside that window keeps the line active.
Is True Vision/Fiber (home service) different?
Yes — home services have contracts. Book an appointment via 1240 and process it with ID; router return is mandatory.
