Official Three bereavement page
Don't cancel the direct debit before you notify them. Broadband and mobile accounts are usually closed or transferred as part of the bereavement process, and cancelling early can cut off a service someone in the household still uses.
What usually happens next
- Contracts in their sole name are usually ended by Three once they have proof of death.
- Someone still living at the address can often take over the line or keep the phone number.
- Ask whether any device balance is outstanding and save photos or messages from the phone before it is closed.
