Roaming charges on personal hotspot while traveling in London?

lpkesq

I will be traveling to London and Dublin soon.  I had planned on turning off roaming on my iphone4, downloading Skype, and making and receiving phone calls only when in a publicly accessible WiFi location.  However, I just acquired a MiFi 4510L mobile hotspot.  I therefore have two questions:

(1)  Will the mobile hotspot work in London and Dublin; and (2)  If I use the hotspot in London and Dublin, so that i can make and receive calls from anywhere, does the hotspot device itself incur roaming charges? Thanks

I do not believe the MiFi's work outside the U.S. as they require the VZW network. However, if they do, the cost of data would be prohibitive.
