Hi
I have a Galaxy S21 on O2 Monthly, which currently is not being used. This phone used to be the old company phone that was supplied to me and we have had upgrades to s23.
My question is, I have my personal O2 Pay Monthly SIM that I would like to use in the S21, when I set it up, it works for about 10 Mins and then refuses to make calls or text, all the other apps work perfectly and the mobile data is fine, but I am unable to make calls or texts. All the network settings are fine. The SIM I want to use is an O2 Monthly sim only and works fine in my personal iPhone 11. Any ideas why?

It's clearly not locked.
