My 16 year old dd has a small amount, 2GB, which I think is the lowest our phone provider does on a contract (Tesco mobile).
Her sleep hygiene is poor (she is autistic), we turn off the wifi on her phone and laptop at night but that's not much good if she is using data!
Does anyone have any ideas what we can do about this? Tesco mobile suggested pay as you go instead of a contract but I don't know exactly how this works.
