Hi, I am a new user of an Android Tablet and last week got a ZeniThink ZT-180 running 2.1 OS. I am desperately trying with no success to get it online via 3G whilst on-the-road. I would like to get it to connect to my iPhones 'Personal Hotspot' (which my Android smartphone connects to with no problem) but my ZT-180 never sees the WiFi hotspot! :-( My tablet does work ok with my home Sky Broadband WiFi. Ok, so no joy with my iPhones hotspot, so I've since tried two different 3G Broadband Dongle/USB Sticks.... plug it into USB, the tablet bleeps and starts to communicate with the dongle but then reports a card failure! Urgh! Please can someone help me? Thanks in advance.
