My Jetpack bar various from 3 to full. LTE and 4G shows however, data moves slower than dial-up. It is literally useless because I can not browse or stream anything since I have arrived in Twentynine Palms in the San Bernardino County. I have a verizon MiFi 7730L. My iPhone also experience the same issue but not as bad as my JetPack. I called customer service and only got the text book help from technical support.
