Short answer

In Viettel you can stop an auto-renewing data package instantly via the My Viettel app or the *098 USSD code; closing the number itself (hủy số) requires visiting a Viettel store with CCCD ID. Prepaid lines have no contract — the line drops 60 days after the balance runs out.

01 — Step-by-step fix

Step-by-step fix

  1. ADIM 01

    Sign in to My Viettel

    Open the My Viettel app and verify with the OTP sent to your number. Open the 'Dịch vụ' (Services) tab on the home screen.

  2. ADIM 02

    Cancel the package in the app

    Find the active package and tap 'Hủy' (Cancel), then confirm. Auto-renewal stops immediately — the package keeps running until the end of its period.

  3. ADIM 03

    Quick cancel via USSD

    Open the dialer and dial *098; choose the package cancellation (hủy gói) option in the menu. A confirmation SMS arrives; the command is free.

  4. ADIM 04

    Visit a store to close the number

    Go to a Viettel store (Showroom) with the owner's CCCD ID and request 'hủy số'. You receive a written request record — keep it.

  5. ADIM 05

    If you want to keep the number

    To avoid losing the number, make a minimal maintenance top-up, or start an MNP request with the new operator: SMS TC <number> to 188; when the port completes the Viettel line closes.

02 — Frequently asked questions

Frequently asked questions

Does cancelling a data package cost anything?

No — package cancellation via My Viettel and *098 is free. Remaining data stays usable until the end of the period.

When does the line drop automatically?

On a prepaid line, after 60 days without a recharge the number is closed irreversibly; a recharge during that window keeps the line alive.

Is the postpaid (trả sau) process different?

Yes — trả sau lines have a contract. Call 1234 customer service or visit a store with ID; the remaining period bill and deposit refund are processed.
