I need help understanding what I need. I have an Android phone with 3-4G. I want to be able to get online when I am in a persons home or out in an area that does not have internet available. Do I need a hotspot or do I need Broadband to Go. I also get messages sometime that there is no network available when I am in my own home, what should I look for to correct this. Thanks for any help I can get.
