Nephew's I phone sent a a total of 5 calls. All of the calls were made on 2/29/11 a few minutes apart and the charges came to $24.21. One of the calls was to this number and the other 4 calls were made to 239 221 6968. We do not make international calls or know in Sao Tome (and had never heard even heard of this island).ATT issued a courtesy credit and we also blocked the phone for international calls. Kudos to ATT.
