I am leaving Mongolia Tuesday morning (Aug 21) and have a six day old G-mobile usb wirelss modem looking for a new owner. It came with 5GB of use for the first 30 days and I think I only used less than 1GB to date. Works perfectly here with a strong signal in camp and pretty fast. It only works in Mongolia.
I am staying at Nature's Door, Lake Khuvsgul. Alternatively, if there is no one nearby I will be in Beijing starting Aug 21 and can hand off to someone on route from there.
