My better half and I have survived without a wireless phone for 60+ years, but for an upcoming drive across country, we've decided maybe we should consider it (it's hard to find a pay phone these days). Since we will use it so little I'm sure a prepaid plan is the best way to go. The companies that seem to offer the best coverage in the areas we will be traveling in (Virginia to New Mexico along I-40 and Northern NM) are T-Mobile and Tracfone. Does anyone have experience with any of these? Are there some others I should consider? Thanks in advance.
