We travel full time in our motor home, so cellular internet is our only decent option. I was surprised when a rep from the 3G store called me a few weeks after my purchase to check on how my Mini was working. After I told him my speeds seemed slow, he walked me thru some troubleshooting. After changing the cellular channel, my speeds improved greatly. Great customer service!
We keep our mini on 24/7 and have never had it drop the connection. BTW, I also purchased a 5 in 1 roof mounted antenna that brings in cell signals from much greater distances. It is worth the cost for our RV lifestyle.
