I have a Nexus 7 wifi-only. I also have a 3 3g dongle which works just fine on my laptop etc. Before getting this Nexus, I had a Momo Ployer IPS which was configured to use the dongle - there was a list of supported dongles of which mine, a Huawei dongle, was one. However, the Momo was not as good as I wanted so I sold it and got the Nexus instead. I attached the dongle (via and adaptor), but I had no joy. My question is: is there any way I could unlock 3g capabilty on my wifi-only Nexus so that it will recognise the dongle, or does the 3g-capable Nexus have additional hardware to make a 3g connection possible. I am runnining Androide 4.2.1. Any suggstions and advice most welcome.
