How do I Find a Bluetooth Phone that is Compatible with Accent?
Even with advanced technology, there are a very limited number of phones available that are capable of sending text messages using a Bluetooth signal. Compatible phones available by Sony Ericsson: W580, W350, W760a, W518a, Equinox TM717, and Motorola Moto z9n. These phones were tested using A T & T and/or T-Mobile wireless support which is GSM network.
Due to rapidly changing technology and phone models, the phones listed may have been discontinued since this article was posted. Before purchasing a new phone, take your device with you to your service provider for a list of available phones and try them out to insure compatibility.
