can anyone tell me what uses a lot of data ? as have a son who managed to use his 500mb of data in 10 days!! first time in 3yrs this has happened but I don't want it to happen again. He is normally very careful but has told me he has been using Skype and been on youtube which is no different than before which is why I find it hard that he managed to use his data so quickly!!
I'm really sorry that a lot of data has been used on the phones. I want to get to the bottom of this for you. To see where the data has been used, log in to your online account here in the usage section.
Let me know how you get on with this. I'm here if you need me.
