O2

Im PAYG. Every time I get a call or message. I get a notification from O2 on my screen with balance & bar down the bottom with 'Dismiss' . Its very annoying & often wont clear immediately when I try. Can I disable it? How? Apologies couldn't find sim...

hi I've ordered a new sim only changing from pay & go to pay monthly - I have £30 credit on old sim can I get refunded for this money ? my new sim is unlimited free minutes and texts. Thanks
