We ordered the KeepGO for Internet-HotSpot Coverage in Mexico

We decided after much research, to purchase the KeepGo Hotspot, which offers the best (purported) coverage in Mexico. We will be going to Baja California and this is the current Coverage map for the KeepGo Hotspot. You can search for your own destination address here. Here is a list of KeepGo Hotspot providers by country, it's pretty extensive but coverage is best in major cities and less so in less populated areas. 

The KeepGo costs a little over $129 and you do not need to replace the SIM card. The data is rather expensive so it is best to use for web browsing, email, etc. Not good for downloads or streaming unless you want to eat up your data. Don't forget to turn off data draining applications like Dropbox and Carbonite. We will update the review when we get the device and test in in Baja and Guanajuato.
