BT has launched the free SmartTalk app to help customers save money on their smartphone calls. The app has been designed to link an iPhone with a customer's home phone calling plan. It works best over Wi-Fi, but will also work over any mobile data connection. It allows BT customers to make phone calls whether in the UK or abroad, and the calls are then billed as if they were made from their BT home phone, including calls to 0800, 0845 and 0870 numbers. Customers will not be charged for making calls that are included as part of their home calling plan. When calling outside of their plan, standard BT landline rates will apply, instead of mobile rates.
