We've had the LX 150 for about three years but have decided to let them expire. The reason for this is that we travel a lot in Wyoming, specifically on I-80 going to Utah, and have no reception or connection at all.
I-wireless uses Sprint as their carrier and Sprint has no cell sites in Wyoming and don't allow roaming. In case of an emergency we would be out of luck trying to call our roadside assistance company.
We have switched to Tracfone LG 420g and have had service all across Wyoming and everywhere we go.
