Get through to O2 without the hold queue

O2's phone line puts an automated security check in front of every call, so you need the security answer on the account before you get anywhere. Once through, billing, upgrades and leaving are all handled here, with the usual wait.

What HoldMyCall does on a O2 call

1
Dials and waits
It rings 0344 809 0202, works through the menu and sits in the queue, however long it takes. You get on with your day.
2
Has the conversation
It introduces itself as an AI assistant calling on your behalf, gives the details you provided when asked, and pushes politely for the outcome you wanted.
3
Reports back
A summary, whether it got what you asked for, any reference numbers, and the full transcript and recording. If they insist on speaking to you, your phone rings and one keypress joins the live call.

Things people ask it to sort with O2

Query the bill

“My bill is higher than usual this month. Find out what the extra charges are and whether any can be removed.”

Confirm the contract end date

“Find out when my contract ends, what the early termination fee would be today, and whether there are any loyalty offers. Don't commit to anything.”

Report a lost phone

“My phone has been lost. Get the SIM blocked, find out about a replacement SIM, and confirm nothing has been charged since yesterday evening.”

Have these ready

Whether you ring or the assistant does, O2 will want some of these before they will talk about your account.

The O2 mobile number on the account
Security answer set on the account
Account holder's name and date of birth

Save them once in Settings and every call starts with them filled in. The assistant only gives a detail when it is asked for it, and it is hard-coded to refuse payments and contract changes.
