Article: It's hard not to feel cheated and over-charged when you receive unexpected roaming charges while traveling abroad--whether they come from making phone calls or checking e-mails. Jeff Gardner received an $ 11,000 bill from Verizon after spending four days in Jamaica. Before the trip, Mr. Gardner, who runs a fly-fishing business in Grayling, Michigan, said he called Verizon to find out what it would cost to use his cellphone for calls and his wireless card to check e-mails while in Jamaica. He said he was told that calls would be about $ 2 a minute and that there would be no extra charges for data as he was on an unlimited plan. _ . "I don't mind paying a fair amount for fair service, but $11,000 for four days is ridiculous," said Mr. Gardner, who used his phone carefully and economically on the trip. He also tried to check and send e-mails using his wireless card, but quickly gave up after the e-mails didn't go through. Still, his Verizon bill said more than 500,000 kilobytes of data was delivered while he was in Jamaica, an amount Mr. Gardner said is 100 times what he normally uses in a month. As travelers increasingly use smart phones abroad in the same way they do at home--to check e-mails, update Facebook and Twitter and pull up online maps--many are facing costly roaming fees, which providers charge when customers use their phones outside their service area. In fact, roaming charges have gotten so out of hand that the Federal Communications Commission has proposed a plan that would require wireless companies to send their customers a voice or text message when they are approaching their plan's limit, when they have reached that limit and when they are starting to result in roaming fees.
Answer: To find out information about roaming charges.

Article: I hate nosy neighbors and it's very unlucky that I had one for myself. They moved in a couple of months back and although I never felt that they were a strange family, I've always hated the way they get "too close" to me, my house, my garden, and even my garbage cans. One day, my neighbors were mowing their lawn . My garbage cans were near their lawn. For some strange reason, I found the wife looking through my garbage cans. I felt angry but since they were from a different culture, I thought that maybe it was "normal" from their ideas. That afternoon, the couple knocked on my front door. When I opened, they gave me a plastic bag. Inside were my old daily bills, credit cards and bank statements, and an old birthday card that my old uncle sent. They said that they were returning them to me because these documents contained very private information that may be used by others. I've heard it before. I asked them how those documents can be used by others and they started telling me their very own experience, which forced them to leave their home and move next door to us. The wife told me that she never destroyed the bills. They also had a "nosy neighbor" who looked through their garbage cans which they actually thought was pretty strange. Little did they know that this "nosy neighbor" was collecting their personal information from their rubbish. Then all their money was taken out from the bank by their neighbor. It was a very painful experience for all of them and they wanted to leave them all behind so they left. I was very thankful. They were not nosy neighbors. They simply didn't want us to experience the same thing that they did.
