New Phone (Pay and go sim card swapped), used £2 of my credit before I switched it on?

I have to admit that this technology is a bit of a new thing for me so forgive me if this seems a bit stupid.

As the subject suggests, I have just got my SIM card swapped and O2 arranged for the account to be switched over but as soon as I switched my new phone on, I discovered I had already used £2 of my credit, how can this be and how do I stop this expense going forward.

My life does not revolve around my phone and I only got this one because the technology nowadays simply doesn't run on an I4-S so I am learning a lot now I am on the A34 5G. I send a few messages, take a few images, make a few calls - pretty basic really.

Thanks in advance.

Go into the phone settings and turn off mobile data.

You can connect to wifi for free data use but using mobile data will eat your credit.
