My husband got an iphone in early September. He has a 200mb data plan. In his first month he used a little over 100mb of his data plan. He is about 10 days into his second month and he received a text today from AT&T that he has used 181mb of his 200mb plan. He said he hasn't done anything differently in the past 10 days vs the first month. Why has he used 181mb of data? What needs to be turned off on his iphone so it doesn't continue to use his data plan when he isn't using the phone?
Thanks!
