O2 are in a different situation. They could lose revenue from people who decide to use a different network instead, as the end user, we only lost a few megabytes of data loss, which, in the grand scheme of things, is a mild annoyance.
Personally I paid £5 for a second SIM which I popped into an older phone. Did I lose a fiver? Nope, I still have that SIM and it's allowances.
I've kept in contact with my friends and family, (unlimited texts) and everyone could contact me.
I haven't relieved an email from GG and I'll ignore it then bin it if one does arrive.
I'd hope the majority of those in the forum will do the same, especially right after payback came in.
