From my experience VODEMS & TSTICKS lose connection frequently and require physical unplugging/replugging when they lockup or overheat...
I believe it is due to the USB port (issues!!)
I need to put a computer in a very remote location and run it on mobile internet connectivity 24/7
As I said, VODEMS overheat & disconnect and cease up in the ports...
I have tried tethering the computer to an iPHONE that is plugged in next to it.
I have turned on PERSONAL HOTSPOT, but it occassionally turns itself off.
I just need 24/7 robust, remote friendly connectivity for this computer to feed off.
If the phones/mobile device occassionally cuts out, I need it to reconnect without the need of a human present....
Hope someone can help
