I have brought a SIM card from O2 to use on my hotspot device. And now I
don't need it anymore. But I don't know how to cancel it. Can I cancel
it via my O2 or do i have to visit the O2 shop?
I think, Im just gonna visit the shop, and ask them to do it for me.
Because I already try to call them on 202 but they respond with some
type of automatic message, which confuse me.
