3G Wireless-n Router - 3G USB Modem compatibility

by will482 / October 8, 2009 10:51 AM PDT

Does anyone know any sites with comparative or in-depth reviews of '3G Wireless-N Routers' that work with the wide variety of 3G USB Modems in the 90+ Countries that have standardised on HSDPA/UMTS ?.

Mobile Broadband is booming, yet there seems to be a lack of 3G Routers (where you plug your 3G USB Modem into the Router, not the laptop) that work interoperably with the wide selection of typically 'Carrier' rebadged, locked USB Modems around the world. It was simple in the days of fixed-telephone-line ISPs and wired DSL Routers. What has gone wrong ? To allow users free use of the 3G modem, if 3G Routers can't borrow the idea in DSL of saving 'Carrier' parameter values to nvram, shouldn't it be/made possible for users to backup/reprogram the 'Carrier' specific part of the firmware to support different 3G networks, particularly for people travelling
internationally where network usually different in every country.
Looking at 3G Router specs, it is not clear if the 'variables' affecting interoperability, are just the make of 3G modem, or also the HSDPA 'Carrier'. Anyone know where to get list of the variables ?

Is there any technical reason why 3G HSDPA USB Modems can't simply use the same firmware, so users need only swop the Carrier's SIM card to connect to the wanted network when moving Country, like with cellular phones ?
