Until it stopped
Until it stopped, the Wifi device worked as expected. However, after using 5-10% of the purchased bandwidth, the device showed that I was at the limit and stopped working. The device and the company insist that i used all 500mb. I monitor the usage on my laptop and I used approximately 35mb of data TOTAL. No where near the 500 claimed. Luckily I was able to use public wifi to complete my trip. So my conclusion is that unless you purchase unlimited bandwidth, this device is completely useless.
