Further to my last post on Roam Mobility on the iPad I bought a Libert Hotspot to provide me 4G service on up to 5 wifi devices. I would prefer to have just my iPad and sim card, but I needed 4g service for a demo that I was giving at a meeting, and we could use this within our marketing group when traveling to the US.
The Liberty Hotspot is made by ZTE and is the same one as sold by t mobile at the same price. The Roam packages are more expensive than t mobile but given the convenience of buying in Canada, they are not too prohibitive.
The hotspot worked flawlessly for me. As soon as I was in the US, turned it on, entered the password into my iPhone wifi configuration and I was online. Coverage for 4G was great in Florida and this worked great for my demo using my laptop.
Roam mentioned that the iPad should get 4G coverage by the end of the year, so I am looking forward to that.
