Box with 3g/4G support

Hello guys which box would you recommend that has 3g/4g capabilities since i don't have a dsl connection at home. I have been looking at the openbox x5 which has 3g modem capabilities. I am looking to use this box for sat 110 and 119. would like if it had epg support as well. any more recommendations?

Openbox X5 is the best. It supports Huawei modems directly. Or just buy a cheap router like TP LINK-MR3020. It'll help to keep connection alive and improve picture quality.

You bring up an important point about keeping connections active. I particularly want a solutions that even if it disconnects will reconnect automatically.
does the tp link router has automatic reconnect?
