Potential new customer here so sorry if this is obvious or is covered/documented elsewhere, but I couldn’t find any info about what I’m after.
Is it possible to USB tether my iPhone to the Mango to then broadcast the signal? Looking to use this as a potential wifi solution for when I’m working away from home and there’s no wifi availible.
Hey & welcome to the forum! 
According to the product page this should be possible!
I don’t have a Mango myself, but I have an Opal, and there it definitely works.
Just keep in mind that the availability of this functionality can of course change due to updates on the smartphones. And of course, it could be that tethering isn’t allowed by your mobile carrier.
Thanks for the quick and useful response
