although on their website, nokia support isnt mentioned anywhere, it does detect the nokia phone as 3G USB modem, here is the "officially" modem support from their website.

and here is my TL-MR3420 configuration that shows Nokia E52-1 as 3G USB Modem.

if somebody mind to ask, why I use my expensive phone as 3G modem on wireless router ???, why not ??, I have unlimited data plan on the phone, and the router is charging the phone too on its USB port. :-D
