Sorry, there was a problem. Please try again later.Hello, reception in your cell phone or the Garvin. I have never yet lost it in the Garvin, but yes in my cell phone I have lost service in seldom areas. Not know much that can be done about the issue. I have Verizon so I find in allot of cases I do have service when others with other providers do not. Hope that helps... Tim
