A:Answer These questions are tough because of the variations in towers, phones, MIFI units. Anyway this MIFI works for me where others have failed as it is better hardware than the older ones. I easily run 5 devices at once. I chose to use MIFI even though I guess the phone can do some mifi also. If you can buy and try in 14 days, thats the best. So my new MIFI works as I have always wanted on the Canadian Border so I can run the ipad and laptop. Hope this helps.
