My Ellipsis 10 takes forever to connect to the Internet after sitting idle overnight!?

We have an Ellipsis 10 that is on LTE only, never connected to WiFi. Every time I let it sit idle for a few hours, it seems to take forever for it to be able to connect to the Internet! This morning I came in and had to keep trying to get Chrome to connect for 15 minutes. Once it gets connected its fine until I set it down for a few hours... What is the issue? Is it the Verizon network or the tablet? My phone is fine and the Ellipsis 8 tablet that we have is fine... Frustrating!
