I am currently using a Samsung i7500. After 6 days of my monthly usage renewing I get a text message saying that I have used up my daily usage of internet. Now I understand that it should be fair and there is a limit however, after a week I couldn't have used up my usage already. I use APNdroid to disconnect it from the internet during the day. I only use it to update my apps and check email thats about it? What do you think is happening?
