Establish what must remain
Plan number retention before ending the line. Keep a way to receive account verification and obtain copies of relevant documents before losing access to the account.
Ask for the final position
Confirm term end, any early termination amount, the device balance and equipment-return deadline. Ending airtime does not necessarily settle a phone repayment. A return also needs evidence of condition and delivery.
Finish using the official route
Keep confirmation of cancellation or transfer and inspect the final statement. Uninstalling an app, removing a SIM profile or cancelling a Direct Debit is not a substitute for the provider’s process. Raise any final-bill question through the official account channel.
