I was sold a pay as you go SIM card by AT&T which was sold as a $2 Unlimited Daily Talk & Text Plan, however charges/debits have been taken from my account from the first day, and 3 days later my balance depleted to half of the original amoutn I had loaded. When calling customer service I was informed that these were GPRS charges, coming from the fact that I was using a smartphone and although I had not signed up for a DATA plan, smartphones automatically make data calls, hence why I was charged, which was without my knowledge nor authorization, and most of all with no prior warning from At&t. THe customer service representative, told me that I should have been warned at the store, that these SIM cards are to be used with feature phones, not smartphones, as this problem happens a lot. At&t credited me only $2 as gesture, whereas my account was already debited $10 and debited rapidly. They then said I should contact the phone maker, and Samsung informed me that it was up to At&t to disable data/internet connections, not the phone manufacturer. At&t disabled the internet afterwards, but claimed that this might get undone without their control. THis is a false offer, which charges which took place without my awareness nor understanding, and I believe At&t is illegally charging customers.
