4g

[Josephinehs]

My 4g isn’t working on my new sim I’ve had it for months . It just doesn’t turn on and when I go on the o2 app it still says I have 15gb and I’ve been trying to sort it for months

You'll need to call customer service.
Numbers here Guide: Coronavirus Community Help and Support 
When it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say "Upgrade", "Lost/Stolen" or "Fraud" if you have to, to get put through to someone.
8.00am is the best time to call if you can.
