O2

Just upgraded SIM only from 20g to 30g for my two children. Went into My O2 to check and its still showing 20g on one of them. Anyone seem this before, please?

I entered the PAC code from my current provider when I ordered a new O2 SIM online. However, my old number is not ported across. Does O2 actually do anything with the PAC code supplied during the order process?

I wanted to buy 2 SIMs, one for each child, I managed to buy one via the online shop. I get a message to say the order cannot be completed when it gets to the credit check step. I am using the same details as per the purchase of the first SIM. Anyone...
