Choose the outcome
If retaining a number, use the transfer sequence before independently terminating the old line. If no number is being retained, ask the provider for the correct closure process and effective date.
Protect other services
Review family lines, wearable subscriptions, home connectivity and add-ons. Removing one line can affect discounts elsewhere. Ask which products remain active and which person is responsible for them.
Device balances
Check the outstanding payment obligation and the treatment of future promotional credits. A service cancellation does not erase a separate handset agreement. Ask for a written breakdown where the figures are unclear.
Keep confirmation
Save the closure date, reference and final billing instructions. Check for later statements or a credit balance. If the final amount differs from the explanation, refer to the recorded details with official support.
