At the end of last billing cycle I received a text msg that I had only about 3G left. 13 min later I record another msg. that I had exceeded my limit of 24 G. At the time I was reading news on my laptop. All the charges were thru the jetpack I was using. Over 3G in 13 min. How can you protect yourself from these kind of charges? I spent about an hour with your rep. going back and forth with typed messages and he agreed that it didn't make sense to him either, Still got charged though.
