My Phones No Longer Work In Crescent Valley Nevada They Used To Work Perfect Her

My phone quit picking up a signal about a week ago spent 3 hours on the phone with teck support and they finally declared it dead, and about 3 days ago my husband was trying to make a call and lost signal, so I called a fried who has a straight talk phone and hers quite too. We have tried almost every thing from dialing the *22890 to taking out the battery. We can get some service about 10 miles outside of our little town but it used to work perfectly here at home and now we dont get anything. We live about 60 miles from anywhere and most of the people here just work here and live somewhere else, we depend on our phones everyday to keep in touch with our families, please please help us with this any information would be greatly appreciated as soon as possible.     Thank you,    [email protected]
