In the past months our data usage is around 300 GB on average, which is far from the 1 TB limit. But this month it said our data usage exceed 90% of data cap. No new devices added and we do not watch TV stream. It is so wierd that 2 people can use up over 900 GB in 20 days and most of the time we are not at home! I have no idea how to deal with it. Is there anyone can kindly help us with it? Thanks.
