This sounds promising - and affordable...
Downside is I already use the OBD2 connector for engine scanning - but in looking at the adapters - am I correct that this is only drawing 12v power from the connector??
(pin 16 = 12v positive; pin 4 = chassis ground)
Seems I could just get this for less than $3 and wire up 12v to it...

(Could also get an OBD2 splitter for less the $10 - but the idea of being able to use away from vehicle is good too...)
Seeing this note in manual makes me think one other (at least) connection is needed:
"Note:
Once the vehicle’s engine has been off for half an hour, the
ZTE Mobley Mobile Hotspot will disconnect and enter Sleep mode."
Though appears there is also a setting for how long till it shuts down - but can't tell if 'unlimited' is a choice...
Am I missing something else??
