Hey there ​@Pebbles28, sorry to hear that. Unfortunately, we cannot cancel data add-ons I’m afaid. 

In terms of being charged, we would text you the moment you’ve used 100% of your data allowances, and then as soon as that happens, you’d begin being charged for further data if you’re still using data past that point. To avoid this in the future, we’d recommend changing plan to a higher data plan as you’ve mentioned, or setting your bill cap to £0.00, so that if you do use all your allowances, you won’t be charged anything past your regular contract cost, as we’d block any further data from being used or any further charges.

Thanks,

Tyler

Hi Tyler, I was notified after I had already been charged. 
Can I change my plan without committing to a long term contract? 

Hi ​@Pebbles28 

I’d recommend checking your iD Mobile app for plan change options.
