The only devices that besides both European frequencies support at least one American one are one specific version of the Huawei E583C and the Vodafone R201 (an OEM device also built by Huawei), which support UMTS900 and UMTS2100 for Europe and UMTS1900 (the latter being used in urban regions by AT&T and T-Mobile in the US).

A bit offtopic, but there's at least one MiFi type device that covers all five UMTS frequencies (850/900/1700/1900/2100MHz) and that's the Huawei E587u-5. It was available from both Telus in Canada for CDN$150 and T-Mobile in the US for $200. The T-Mobile version was rebranded as a T-Mobile Sonic 4G).

Some dealers still sell it: Buy Unlocked T-Mobile Sonic 4G Mobile HotSpot 4G Router | Huawei UMG587 | E587u-5 | 4GSource.net Wholesale Shop
