Keep getting the same error when I try the 4G setup assistant on your website. Enter SMS code, chose phone, get error. (tried different browsers and machines multiple times over the last two days).
I have an existing contract, received an updated SIM yesterday from O2 which is activated and I have a 4G capable phone. But now I want to get service upgraded to 4G.
Your website doesn't work and you don't answer the phone (Keeps cutting out after going through the menus) .Still waiting on a call back from texting 'CHAT'.
