Pay as you go cell phones

We're in a valley (dead zone) so get no reception. I don't want to pay for cell service I can't use (already did that), so I'm looking at go phones, for when I head to Topeka, or anywhere else for that matter. Are there any with decent coverage? My son's Virgin Mobile doesn't work past Russell, so that is off the list. I'm wanting coverage for the occasional trip to Hays and Wichita, basically following the interstates.

What you need is possibly a repeater or a booster?

trac phone

tracfone is a good phone and they use everybody elses towers and the kids had 'em,I used one when I took baby to California for his heart surgery and I'd have to say that may be your best bet.and they are cheap

Trac phone is your best deal.
