Hi Jerome,
Just reading this with interest. I have a few of these deployed and just researching an intermittant connection on one of them, I can see on all, under carrier aggregation in 'Status/Network/Mobile' that it says single.
The LTE settings are on auto appart from switching off GSM and 3G.
Do you know if this indicates that it's 'set' to single mast or just picking up a single mast??
Cheers, Dave
