OK Bob, have just updated the time to 2 hours as that was the only option available. There was no unlimited option - unless there is another place to look besides the Power Save
Recently had Mobley problems after 4-5 years no problems. Finally got onto ZTE tech support and he had me do a Reset. So now it works - for about a half hour and then is off. How do i fix this?ThanksDavidKerrville, TX
