 Samsung stated that they were working with Southwest Airlines to investigate the incident, but stated that they would be unable to confirm whether the device was a replacement model until it was recovered.On 7 October 2016, a third replacement phone in Minnesota had reportedly caught fire in a similar manner.In response to these incidents involving replacement phones, the United States' five major wireless carriers (AT&T Mobility and T-Mobile US on 9 October, along with Sprint Corporation, Verizon Wireless, and U.S. Cellular on 10 October) subsequently announced that they would suspend sales of the Galaxy Note 7 until further notice, pending an investigation.
