Sorry, had overlooked the date so obviously I'm getting to excited for this. I'll wait out and the message does say we shouldn't have to do anything 😅
"CONTRACT CHANGE from 48: By 31st October, your plan will include access to the 5G network where available, at no additional cost. You may get access sooner as we start the rollout from next week. Your price and allowances are not changing. You don't need to do anything, we'll automatically activate 5G on your account."
